The geometric average of -10%, 20%, and 40% is approximately -20.2%.

To find the geometric average of a set of numbers, you need to multiply them together and then take the nth root, where n is the number of values.

In this case, we have three values: -10%, 20%, and 40%.

Step 1: Convert the percentages to decimal form by dividing by 100.

-10% becomes -0.10

20% becomes 0.20

40% becomes 0.40

Step 2: Multiply the decimal values together.

-0.10 * 0.20 * 0.40 = -0.008

Step 3: Take the cube root (since we have three values) of the result.

∛(-0.008) ≈ -0.202

Step 4: Convert the result back to a percentage by multiplying by 100.

-0.202 * 100 ≈ -20.2%

Therefore, the geometric average of -10%, 20%, and 40% is approximately -20.2%.

The set S = {-1, 1, 1} forms a basis of ℝ³, and the orthonormal basis T = {1, 0, 0} is obtained through the Gram-Schmidt orthonormalization process.

To show that the set S = {X₁, X₂, X₃} = {-1, 1, 1} forms a basis of ℝ³ and find an orthonormal basis T = {Y₁, Y₂, Y₃} using the Gram-Schmidt orthonormalization process, we'll follow the steps of the process.

Step 1:

Verify linear independence of S:

We need to check if the vectors in S are linearly independent. If they are linearly independent, then S will form a basis of ℝ³.

Set up a linear combination equation:

a₁X₁ + a₂X₂ + a₃X₃ = 0

Substituting the values of X₁, X₂, and X₃:

-a₁ + a₂ + a₃ = 0

We can observe that for a₁ = 1, a₂ = 1, and a₃ = 1, the equation is satisfied. Therefore, the only solution to the linear combination equation is the trivial solution a₁ = a₂ = a₃ = 0. Hence, the vectors in S are linearly independent.

Step 2:

Normalize the vectors:

To find an orthonormal basis using Gram-Schmidt, we need to normalize the vectors in S.

Y₁ = X₁ / ||X₁||

= X₁ / √(X₁ · X₁)

= X₁ / √((-1)²)

= -X₁

Y₂ = X₂ - projₙ(Y₁)

= X₂ - ((X₂ · Y₁) / (Y₁ · Y₁)) Y₁

Calculating the projection:

X₂ · Y₁ = (1) · (-1) = -1

Y₁ · Y₁ = (-1) · (-1) = 1

Y₂ = X₂ - (-1 / 1) (-X₁)

= X₂ + X₁

= 1 + (-1)

= 0

Y₃ = X₃ - projₙ(Y₁) - projₙ(Y₂)

= X₃ - ((X₃ · Y₁) / (Y₁ · Y₁)) Y₁ - ((X₃ · Y₂) / (Y₂ · Y₂)) Y₂

Calculating the projections:

X₃ · Y₁ = (1) · (-1) = -1

X₃ · Y₂ = (1) · (0) = 0

Y₃ = X₃ - (-1 / 1) (-X₁) - (0 / 0) Y₂

= X₃ + X₁

= 1 + (-1)

= 0

Now, we have the orthonormal basis T = {Y₁, Y₂, Y₃} = {-X₁, 0, 0} = {1, 0, 0}.

b) if the investment plan pays you 12% per year for the first 20 years and 6% per year for the next 20 years:

a. To calculate the amount you need to invest today to become a millionaire in 40 years, we can use the formula for the future value of a lump sum:

[tex]FV = PV * (1 + r)^n[/tex]

Where:

FV = Future value (desired amount, $1,000,000)

PV = Present value (amount to be invested today)

r = Annual interest rate (11.4% or 0.114)

n = Number of years (40)

Rearranging the formula to solve for PV:

[tex]PV = FV / (1 + r)^n[/tex]

Substituting the given values:

[tex]PV = $1,000,000 / (1 + 0.114)^4^0[/tex]

[tex]PV = $51,982.88[/tex]

Therefore, you would need to invest approximately $51,982.88 today.

b. Using the same formula, but with an annual interest rate of 5.7% or 0.057:

[tex]PV = \$1,000,000 / (1 + 0.057)^4^0[/tex]

[tex]PV =\$179,216.54[/tex]

Therefore, if you can earn an annual return of 5.7%, you would need to invest approximately $179,216.54 today.

a. To calculate the amount you will have at the end of 40 years with an investment plan that pays 6% per year for the first 20 years and 12% per year for the last 20 years, we can use the formula for the future value of a lump sum:

[tex]FV = PV * (1 + r)^n[/tex]

For the first 20 years:

[tex]PV = $20,000[/tex]

r = 6% or 0.06

n = 20

[tex]FV1 = $20,000 * (1 + 0.06)^2^0[/tex]

For the last 20 years:

PV2 = FV1 (the amount accumulated after the first 20 years)

[tex]r = 12\% or 0.12[/tex]

n = 20

[tex]FV = FV1 * (1 + 0.12)^2^0[/tex]

Calculating FV1:

[tex]FV1 = \$20,000 * (1 + 0.06)^2^0[/tex]

[tex]FV1 =\$66,434.59[/tex]

Calculating FV:

[tex]FV = \$66,434.59 * (1 + 0.12)^2^0[/tex]

[tex]FV = \$1,062,612.42[/tex]

Therefore, at the end of 40 years, you would have approximately [tex]\$1,062,612.42.[/tex]

The angle measures 154.6 degrees, while its supplementary angle measures 25.4 degrees.

Let's assume the measure of the angle is x degrees. The supplementary angle to this angle would be 180 - x degrees, as supplementary angles add up to 180 degrees.

According to the given information, the angle measures 129.2° more than its supplementary angle. Mathematically, this can be expressed as:

x = (180 - x) + 129.2

Simplifying the equation, we can combine like terms:

2x = 180 + 129.2

2x = 309.2

Dividing both sides of the equation by 2, we get:

x = 154.6

Therefore, the angle measures 154.6 degrees, and its supplementary angle measures (180 - 154.6) = 25.4 degrees.

To verify our answer, we can check if the sum of the angle and its supplementary angle equals 180 degrees:

154.6 + 25.4 = 180

Indeed, the sum is 180 degrees, which confirms that our solution is correct. Thus, the measure of the angle is 154.6 degrees, and the measure of its supplementary angle is 25.4 degrees.

L((7,8)) = (-9,23).  To find the value of L((7,8)), we can use the linearity property of the linear operator L.

Since L is a linear operator, we can express any vector in R² as a linear combination of the basis vectors (1,0) and (0,1).

We have L((1,2)) = (-2,3) and L((1,-1)) = (5,2). Therefore, we can express (7,8) as (7,8) = 7(1,2) + 1(1,-1).

Using the linearity property, we can distribute the linear operator L over the linear combination:

L((7,8)) = L(7(1,2) + 1(1,-1))

= 7L((1,2)) + L((1,-1))

= 7(-2,3) + (5,2)

To find the standard error of the estimate, we need to calculate the residuals and their sum of squares.

The residuals (ei) can be obtained by subtracting the predicted values (ŷi) from the actual values (yi).  The predicted values can be calculated using a regression model.

Using the given data:

xi: 2 6 9 13 20

yi: 7 16 10 24 21

We can use linear regression to find the predicted values (ŷi). The regression equation is of the form ŷ = a + bx, where a is the intercept and b is the slope.

Calculating the regression equation, we get:

a = 10.48

b = 0.8667

Using these values, we can calculate the predicted values (ŷi) for each xi:

ŷ1 = 12.21

ŷ2 = 15.75

ŷ3 = 18.41

ŷ4 = 21.94

ŷ5 = 26.68

Now, we can calculate the residuals (ei) by subtracting the predicted values from the actual values:

e1 = 7 - 12.21 = -5.21

e2 = 16 - 15.75 = 0.25

e3 = 10 - 18.41 = -8.41

e4 = 24 - 21.94 = 2.06

e5 = 21 - 26.68 = -5.68

Next, we square each residual and calculate the sum of squares of the residuals (SSR):

SSR = e1^2 + e2^2 + e3^2 + e4^2 + e5^2 = 83.269

To find the standard error of the estimate (SE), we divide the SSR by the degrees of freedom (df), which is the number of data points minus the number of parameters in the regression model:

df = n - k - 1

Here, n = 5 (number of data points) and k = 2 (number of parameters: intercept and slope).

df = 5 - 2 - 1 = 2

SE = sqrt(SSR/df) = sqrt(83.269/2) ≈ 7.244

(a) The value of the standard error of the estimate is approximately 7.244.

(b) To test for a significant relationship using the t test, we compare the t statistic to the critical t value at the given significance level (α = 0.05).

The null and alternative hypotheses are:

H0: β1 = 0 (There is no significant relationship between x and y)

Ha: β1 ≠ 0 (There is a significant relationship between x and y)

To find the value of the test statistic, we need additional information such as the sample size, degrees of freedom, and the estimated standard error of the slope coefficient. Without this information, we cannot determine the exact value of the test statistic.

The choice of plan depends on various factors such as budget, usage requirements, and personal preferences.

Shawn and Elena have chosen different plans for their subscription services. Shawn's plan includes a one-time sign-up fee of $95, followed by a monthly charge of $20.

This means that Shawn will pay $95 upfront to activate the plan, and then he will be billed $20 each month for the service. This type of pricing model is commonly seen in subscription-based services, where customers have to pay an initial fee to access the service and then a recurring monthly fee to maintain their subscription.

On the other hand, Elena has opted for a different plan that charges a flat rate of $35 per month. This means that Elena will be charged $35 every month for the service, without any additional one-time fees or charges.

Shawn's plan, with a higher initial fee but a lower monthly charge, may be more suitable for those who are willing to invest upfront and anticipate long-term usage.

Elena's plan, with a lower monthly charge but no initial fee, might be preferred by those who prefer a lower upfront cost and flexibility in canceling the service without any additional financial implications.

The value for which only about 5% of healthy children have a smaller left atrial diameter is approximately 22.6 mm.

The left atrial diameter of healthy children is assumed to be approximately normally distributed with a mean of 28.4 mm and a standard deviation of 3.5 mm. We need to find the left atrial diameter for which only 5% of the healthy children have a smaller atrial diameter.

We will use the Z-score formula to find the Z-score value. The Z-score formula is:

Z = (x - μ) / σ

where x is the observation, μ is the population mean, and σ is the population standard deviation. Substituting the given values, we get:

Z = (x - 28.4) / 3.5

To find the left atrial diameter for which only 5% of the healthy children have a smaller diameter, we need to find the Z-score such that the area under the standard normal distribution curve to the left of the Z-score is 0.05. This can be done using a standard normal distribution table or a calculator that has a normal distribution function.

Using a standard normal distribution table, we find that the Z-score for an area of 0.05 to the left is -1.645 (approximately).

Substituting Z = -1.645 into the Z-score formula above and solving for x, we get:

-1.645 = (x - 28.4) / 3.5

Multiplying both sides by 3.5, we get:

-5.7675 = x - 28.4

Adding 28.4 to both sides, we get:

First problem:

Determine the compound amount if BHD 12,000 is invested at 1% compounded monthly for 790 days.

To calculate the compound amount, we can use the formula:

A = P(1 + r/n)^(nt)

Where:

A = Compound amount

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times interest is compounded per year

t = Time period in years

In this case, the principal amount (P) is BHD 12,000, the annual interest rate (r) is 1% (or 0.01 as a decimal), the interest is compounded monthly, so n = 12, and the time period (t) is 790 days, which is approximately 2.164 years (790/365.25).

Plugging these values into the formula, we have:

A = 12000(1 + 0.01/12)^(12*2.164)

Calculating the compound amount gives us:

A ≈ 12,251.84

Therefore, the compound amount after 790 days would be approximately BHD 12,251.84.

Second problem:

Find the discount value on BHD 31,200 at the end of 350 days if it is invested at 3% compounded quarterly.

Where:

D = Discount value

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times interest is compounded per year

t = Time period in years

In this case, the principal amount (P) is BHD 31,200, the annual interest rate (r) is 3% (or 0.03 as a decimal), the interest is compounded quarterly, so n = 4, and the time period (t) is 350 days, which is approximately 0.9589 years (350/365.25).

Plugging these values into the formula, we have:

D = 31200(1 - 0.03/4)^(4*0.9589)

By solving the system of equations and checking the solutions, we can determine if S is linearly independent and if it spans P₂.

a) To determine if the function f(t) = t² - t - 1 is in the span of S = {f₁, f₂, f₃}, we need to check if we can find scalars a, b, and c such that f(t) = af₁(t) + bf₂(t) + cf₃(t).

Let's set up the equation:

f(t) = a(f₁(t)) + b(f₂(t)) + c(f₃(t))

f(t) = a(t² - 2t - 3) + b(t² - 4t - 2) + c(t² + 2t - 5)

f(t) = (a + b + c)t² + (-2a - 4b + 2c)t + (-3a - 2b - 5c)

For f(t) to be in the span of S, the coefficients of t², t, and the constant term in the above equation should match the coefficients of t², t, and the constant term in f(t).

Comparing the coefficients, we get the following system of equations:

a + b + c = 1

-2a - 4b + 2c = -1

-3a - 2b - 5c = -1

By solving this system of equations, we can find the values of a, b, and c. If a solution exists, then f(t) is in the span of S.

b) To determine if S = {f₁, f₂, f₃} is a set of linearly independent functions, we need to check if the only solution to the equation a₁f₁(t) + a₂f₂(t) + a₃f₃(t) = 0 is when a₁ = a₂ = a₃ = 0.

Let's set up the equation:

a₁f₁(t) + a₂f₂(t) + a₃f₃(t) = 0

a₁(t² - 2t - 3) + a₂(t² - 4t - 2) + a₃(t² + 2t - 5) = 0

The GCD of 2613 and 2171 is 61.The GCD of 2613 and 2171 is 1. It can be expressed as a linear combination of the two numbers as GCD(2613, 2171) = 2613 + (-2) * 2171.

To find the GCD (Greatest Common Divisor) of 2613 and 2171, we can use the Euclidean algorithm. We divide the larger number by the smaller number and take the remainder. Then we replace the larger number with the smaller number and the smaller number with the remainder. We repeat this process until the remainder becomes zero. The last non-zero remainder will be the GCD.

1. Divide 2613 by 2171: 2613 ÷ 2171 = 1 with a remainder of 442.

2. Divide 2171 by 442: 2171 ÷ 442 = 4 with a remainder of 145.

The simplified form of the trigonometric expression cosθ/sinθcotθ is 1/sinθ.

We start by simplifying the expression using the reciprocal and quotient identities. The cotangent of θ is defined as cosθ/sinθ. Thus, we can rewrite the expression as cosθ/(sinθ × cosθ/sinθ).

Next, we simplify the expression by canceling out the common factors. The sinθ in the numerator cancels out with one of the sinθ terms in the denominator, and the cosθ in the denominator cancels out with the remaining cosθ in the numerator.

As a result, we are left with 1/sinθ. This is because sinθ/sinθ simplifies to 1.

b). The possible values of x are x = -1 and x = 4

First term: x−5

Second term: x−1

Third term: 2x+1

Common ratio = (Second term) / (First term)

= (x−1) / (x−5)

Third term = (Second term) × (Common ratio)

The equation in a standard form that has the solutions y = 1/7 and y = 7.

To find an equation with the given solutions y = 1/7 and y = 7, we can use the fact that the solutions of a quadratic equation are given by the formula:

y = ax^2 + bx + c

We know that the solutions are y = 1/7 and y = 7, so we can set up two equations based on these solutions:

1/7 = a(1/7)^2 + b(1/7) + c -- Equation 1

7 = a(7)^2 + b(7) + c -- Equation 2

Simplifying Equation 1:

1/7 = a/49 + b/7 + c

Multiplying through by 49 to eliminate the fractions:

7 = a + 7b + 49c

Simplifying Equation 2:

7 = 49a + 7b + c

Now, we have a system of linear equations:

7 = a + 7b + 49c -- Equation 3

7 = 49a + 7b + c -- Equation 4

To eliminate variables, we can subtract Equation 3 from Equation 4:

0 = 48a - 48c

Dividing by 48:

0 = a - c

We can substitute this value back into Equation 3:

7 = (a - c) + 7b + 49c

Simplifying:

7 = a + 7b + 48c

The correct answer is OTV/4. To find the value of ω for which Ares = √2A, we need to equate the two expressions for amplitude: √2A = A sin(ωt + p). Therefore, the value of ω is OTV/4.

To find the value of ω for which Ares = √2A, we need to equate the two expressions for amplitude:

√2A = A sin(ωt + p)

Simplifying the equation, we get:

√2 = sin(ωt + p)

To find the value of ω, we need to determine the angle at which the sine function equals √2. This occurs at ωt + p = π/4.

Therefore, the value of ω is OTV/4.

When two waves are described by the equations y1 = A sin(kx - ωt) and y2 = A sin(kx - ωt + p), the amplitude of each wave is represented by the value A. In this problem, we are given that the amplitude Ares is equal to √2A.

To determine the value of ω that satisfies this condition, we equate the two expressions for amplitude:

Ares = √2A

Simplifying the equation, we have:

√2 = sin(kx - ωt + p)

Since the sine function ranges from -1 to 1, we need to find the angle at which sin(kx - ωt + p) equals √2. This angle is π/4.

Therefore, we set the expression inside the sine function equal to π/4:

kx - ωt + p = π/4

Now, we need to solve for ω. Rearranging the equation, we have:

-ωt = -kx + p + π/4

Dividing both sides by -t, we get:

ω = (kx - p - π/4) / t

Since the values of k, x, p, and t are not given in the problem, we cannot calculate the exact numerical value of ω. However, we can simplify the expression:

ω = (kx - p - π/4) / t

The given answer choices are OTV/4, O 31/2, OT/3, and 211/3. None of these choices explicitly match the simplified expression for ω. It's possible that the answer choices were transcribed incorrectly or that there is a typo in the original question.

In any case, the correct answer should be the value of ω that satisfies the equation derived earlier:

ω = (kx - p - π/4) / t

Further information about the values of k, x, p, and t would be required to calculate the exact numerical value of ω.

When Tracey pours all the water from the smaller 5-inch cube container into the larger 7-inch cube container, the water will be approximately 7 inches deep in the larger container.

To find out how deep the water will be in the larger container, we need to consider the volume of water transferred from the smaller container. Since both containers are cube-shaped, the volume of each container is equal to the length of one side cubed.

The volume of the smaller container is 5 inches * 5 inches * 5 inches = 125 cubic inches.

When Tracey pours all the water from the smaller container into the larger container, the water completely fills the larger container. The volume of the larger container is 7 inches * 7 inches * 7 inches = 343 cubic inches.

Since the water fills the larger container completely, the depth of the water in the larger container will be equal to the height of the larger container. Since all sides of the larger container have the same length, the height of the larger container is 7 inches.

Therefore, the water will be approximately 7 inches deep in the larger container.

To find the height of the tree, we can use trigonometry and create a triangle using the given angles and distances

1. In the first sighting:

tan (68°) = h / x, where x is the distance between the landscaper and the tree.

2. In the second sighting:

tan (43°) = h / (x + 70), where x + 70 represents the new distance between the landscaper and the tree.

1. h = x * tan (68°)

2. h = (x + 70) * tan (43°)

Since both expressions equal the height of the tree, we can set them equal to each other:

x * tan (68°) = (x + 70) * tan (43°)

Now we can solve this equation to find the value of x:

x ≈ 79.8 ft

With x ≈ 79.8 ft, we can substitute it into one of the equations to find the height of the tree:

h = x * tan (68°) ≈ 79.8 * tan (68°) ≈ 186.6 ft

Therefore, the height of the tree is approximately 186.6 feet to the nearest tenth of a foot.

For the non-homogeneous problem y" - 6y + 10y = 360 sin(2x), we first find the complementary solution by solving the homogeneous problem y" - 6y + 10y = 0.

The roots of the auxiliary equation are 3+1 and 3-i,

leading to a fundamental set of solutions e^(3x)cos(x) and e^(3x)sin(x). Using these solutions, we obtain the complementary solution C1e^(3x)cos(x) + C2e^(3x)sin(x).

Next, we seek a particular solution using the method of undetermined coefficients.

By applying the method, we find the particular solution yp = 24cos(2x) + 12sin(2x).

The general solution is then given by y = C1e^(3x)cos(x) + C2e^(3x)sin(x) + 24cos(2x) + 12sin(2x).

To solve an initial value problem (IVP) with y(0) = 25 and y'(0) = 26, we substitute these values into the general solution to find the unique solution

The given non-homogeneous problem is a second-order linear differential equation with variable coefficients. To find the general solution, we first solve the corresponding homogeneous problem by setting the right-hand side to zero.

The auxiliary equation is obtained by replacing the derivatives with the characteristic equation: r^2 - 6r + 10 = 0. Solving this quadratic equation gives us the roots 3+1 and 3-i.

From these roots, we find a fundamental set of solutions using the formulas e^(ax)cos(bx) and e^(ax)sin(bx).

Thus, the complementary solution is C1e^(3x)cos(x) + C2e^(3x)sin(x), where C1 and C2 are arbitrary constants.

To determine a particular solution, we use the method of undetermined coefficients.

We assume a solution of the form yp = Acos(2x) + Bsin(2x) and find the values of A and B by substituting this into the non-homogeneous equation and comparing coefficients.

Let A = [2 4 0 -3 -5 0 3 3 -2] Find an invertible matrix P and a diagonal matrix D such that D = P^-1 AP.In order to find the diagonal matrix D and the invertible matrix P such that D = P^-1 AP, we need to follow the following steps:

STEP 1: The first step is to find the eigenvalues of matrix A. We can find the eigenvalues of the matrix by solving the determinant of the matrix (A - λI) = 0. Here I is the identity matrix of order 3.

[tex](A - λI) = \begin{bmatrix} 2-λ & 4 & 0 \\ -3 & -5-λ & 0 \\ 3 & 3 & -2-λ \end{bmatrix}[/tex]

Let the determinant of the matrix (A - λI) be equal to zero, then:

[tex](2 - λ) [(-5 - λ)(-2 - λ) - 3.3] - 4 [(-3)(-2 - λ) - 3.3] + 0 [-3.3 - 3(-5 - λ)] = 0 (2 - λ)[λ^2 + 7λ + 6] - 4[6 + 3λ] = 0 2λ^3 - 9λ^2 - 4λ + 24 = 0[/tex] The cubic equation above has the roots [tex]λ1 = 4, λ2 = -2 and λ3 = 3[/tex].

STEP 2: The second step is to find the eigenvectors associated with each eigenvalue of matrix A. To find the eigenvector associated with each eigenvalue, we can substitute the eigenvalue into the equation

[tex](A - λI)x = 0 and solve for x. We have:(A - λ1I)x1 = 0 => \begin{bmatrix} 2-4 & 4 & 0 \\ -3 & -5-4 & 0 \\ 3 & 3 & -2-4 \end{bmatrix} x1 = 0 => \begin{bmatrix} -2 & 4 & 0 \\ -3 & -9 & 0 \\ 3 & 3 & -6 \end{bmatrix} x1 = 0 => x1 = \begin{bmatrix} 2 \\ 1 \\ 1 \end{bmatrix}[/tex]

Let x1 be the eigenvector associated with the eigenvalue λ1 = 4.

STEP 3: The third step is to form the diagonal matrix D. To form the diagonal matrix D, we place the eigenvalues λ1, λ2 and λ3 along the main diagonal of the matrix and fill in the other entries with zeroes. [tex]D = \begin{bmatrix} 4 & 0 & 0 \\ 0 & -2 & 0 \\ 0 & 0 & 3 \end{bmatrix}[/tex]

STEP 4: The fourth and final step is to compute [tex]P^-1 AP = D[/tex].

We can compute [tex]P^-1[/tex] using the formula

[tex]P^-1 = adj(P)/det(P)[/tex] , where adj(P) is the adjugate of matrix P and det(P) is the determinant of matrix P.

[tex]adj(P) = \begin{bmatrix} 1 & 0 & 2 \\ -1 & 1 & 2 \\ -2 & 0 & 2 \end{bmatrix} and det(P) = 4[/tex]

Simplifying, we get:

[tex]P^-1 AP = D = \begin{bmatrix} 4 & 0 & 0 \\ 0 & -2 & 0 \\ 0 & 0 & 3 \end{bmatrix}[/tex]

The invertible matrix P and diagonal matrix D such that [tex]D = P^-1[/tex]AP is given by:

P = [tex]\begin{bmatrix} 2 & -2 & 0 \\ 1 & 1 & 0 \\ 1 & 0 & 1 \end{bmatrix} and D = \begin{bmatrix} 4 & 0 & 0 \\ 0 & -2 & 0 \\ 0 & 0 & 3 \end{bmatrix}.[/tex]

The hyperbola is centered at the midpoint between the two airports and its branches extend towards each airport. The branch representing the flight path is the one where the signal from your airport arrives first (100 μs earlier).

In this scenario, we have two airports located 48 km apart. The pilot's instrument panel receives radio signals from both airports simultaneously, but there is a time delay between the signals due to the distance and speed of transmission.

Let's assume that the pilot's instrument panel is at the center of the hyperbola. The distance between the two airports is 48 km, so the midpoint between them is at a distance of 24 km from each airport.

Since the signal from your airport always arrives 100 μs earlier than the signal from the other airport, it means that the hyperbola is oriented such that the branch representing the flight path is closer to your airport.

To draw the hyperbola, we mark the midpoint between the two airports and draw two branches extending towards each airport. The branch that is closer to your airport represents the flight path, as it indicates that the signal from your airport reaches the pilot's instrument panel earlier.

The other branch of the hyperbola represents the signals arriving from the other airport, which have a delay of 100 μs compared to the signals from your airport.

When a triangle is dilated at a scale factor of k, the ratio of the sines of corresponding angles in the original and dilated triangles is equal to 1/k. In this specific case, since the scale factor is 2, the proportion sin(zD) / sin(A) equals 1/2.

To determine the proportion that proves sin(zD) = sin(A) in the dilated triangles BAC and BDE, we need to consider the properties of dilations and the corresponding angles in similar triangles.

When a triangle is dilated by a scale factor of k, the corresponding angles in the original and dilated triangles remain congruent. However, the side lengths are multiplied by the scale factor. In this case, triangle BAC is dilated from triangle BDE at a scale factor of 2, meaning that all side lengths of BAC are twice as long as the corresponding side lengths of BDE.

Let's consider angle D in triangle BDE and angle A in triangle BAC. Since the triangles are similar, angle D is congruent to angle A.

Now, let's examine the sine function. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.

In triangle BDE, the side opposite angle D is DE, and in triangle BAC, the side opposite angle A is AC. Since triangle BAC is a dilation of triangle BDE with a scale factor of 2, the length of AC is twice the length of DE.

Based on this information, we can set up the proportion:

sin(zD) / sin(A) = DE / AC

However, since AC = 2DE (due to the dilation), we can substitute this value into the proportion:

sin(zD) / sin(A) = DE / (2DE)

= 1/2

Therefore, the proportion that proves sin(zD) = sin(A) is:

sin(zD) / sin(A) = 1/2
