A baseballs height in feet t seconds after it is hit is given by f(t) = -16t^2 + 132t + 4
Find f(3) and explain its meaning in the context of this problem.
When did the ball reach its maximum height?
What is the maximum height of the ball?

Answers

Answer 1


f(3) = -16(3)^2 + 132(3) + 4 = 376
The height of the baseball 3 seconds after it was hit is 376 feet.

The ball reaches its maximum height at the vertex of the parabola. The x-coordinate of the vertex is given by -b/2a, where a = -16 and b = 132. Therefore, the x-coordinate of the vertex is x = -b/2a = -132/(2(-16)) = 4.125 seconds.

To find the maximum height, we can substitute this value of x into the equation for f(t):

f(4.125) = -16(4.125)^2 + 132(4.125) + 4 = 275.5

Therefore, the ball reaches its maximum height after 4.125 seconds, and the maximum height of the ball is 275.5 feet.

A cylinder has a volume of 400 feet. If the height of the cylinder is 25 feet, what is the radius of the cylinder? Use 3.14 for π and a round to the nearest hundredth. radius ≈ type your answer… ft

Answers

Answer:

the radius of the cylinder is approximately 2.26 feet.

Step-by-step explanation:

To find the radius of the cylinder, we can use the formula for the volume of a cylinder:

Volume = π * radius^2 * height

Given that the volume is 400 feet, the height is 25 feet, and using π ≈ 3.14, we can rearrange the formula to solve for the radius:

400 = 3.14 * radius^2 * 25

Divide both sides of the equation by (3.14 * 25):

400 / (3.14 * 25) = radius^2

Simplifying:

400 / 78.5 ≈ radius^2

5.09 ≈ radius^2

To find the radius, we take the square root of both sides:

√5.09 ≈ √(radius^2)

2.26 ≈ radius

Rounding to the nearest hundredth, the radius of the cylinder is approximately 2.26 feet.

Answer:

Step-by-step explanation:

Volume Formula for a cylinder is  V=πr²h

Substitute the following:    400 = 3.14(r²)(25)

r=[tex]\sqrt{\frac{V}{\pi h} }[/tex]

r=[tex]\sqrt{\frac{400}{\pi 25} }[/tex]

r≈2.25676ft

Let

BB represent the number of bags of avocados that Alonso buys.

Answers

Alonso spent all of his money, this confirms that he can buy 3 bags of avocados.

Alonso has $21.00 to spend on eggs and avocados. He buys eggs that cost $2.50, which leaves him with $18.50. Since the store only sells avocados in bags of 3, he will need to find the cost per bag in order to calculate how many bags he can buy.

First, divide the cost of 3 avocados by 3 to find the cost per avocado. $5.00 ÷ 3 = $1.67 per avocado.

Next, divide the money Alonso has left by the cost per avocado to find how many avocados he can buy.

$18.50 ÷ $1.67 per avocado = 11.08 avocados.

Since avocados only come in bags of 3, Alonso needs to round down to the nearest whole bag. He can buy 11 avocados, which is 3.67 bags.

Thus, he will buy 3 bags of avocados.Let's test our answer to make sure that Alonso has spent all his money:

$2.50 for eggs3 bags of avocados for $5.00 per bag, which is 9 bags of avocados altogether. 9 bags × $5.00 per bag = $45.00 spent on avocados.

Total spent:

$2.50 + $45.00 = $47.50

Total money had:

$21.00

Remaining money:

what is (0.3)0 in binominal distribution

Answers

Answer:

When p, the probability of success, is zero in a binomial distribution, the probability of getting exactly k successes in n trials is also zero for all values of k except when k is zero (i.e., when there are no successes).

So, in the case of (0.3)^0, the result would be 1, because any number raised to the power of 0 is equal to 1. Therefore, the probability of getting zero successes in a binomial distribution when the probability of success is 0.3 is 1.

Deepak wrote out the steps to his solution of the equation StartFraction 5 Over 2 minus 3 x minus 5 plus 4 x equals negative StartFraction 7 Over 4 EndFraction – 3x – 5 + 4x = –.

Answers

The solution to the given equation is x = -1/4.To solve the equation, let's break down the steps as outlined by Deepak:

Combine like terms: Starting with the left side of the equation, combine the x terms and the constant terms separately. On the left side, we have -3x and 4x, which can be combined to give x. Similarly, we have -5 and 5, which cancel each other out, leaving us with zero.

Simplify both sides: Now, the equation becomes x = -7/4 - 3x.

Move all the x terms to one side: To isolate the x term on one side, we can add 3x to both sides of the equation. This gives us 4x + 3x = -7/4.

Combine like terms: On the left side, we have 4x and 3x, which can be added to give 7x. The equation now becomes 7x = -7/4.

Solve for x: To solve for x, we divide both sides of the equation by 7. This yields x = -1/4.

Therefore, the solution to the given equation is x = -1/4.

For part 2, I know the answer but I'm not sure how to get to it

Answers

Answer:

Step-by-step explanation:

To evaluate the expression {p - q, p - q}, which represents the inner product of the polynomial (p - q) with itself, you can follow these steps:

Given p(x) = 5x^2 - x - 3 and q(x) = 2x^2 + 4x - 3.

Subtract q(x) from p(x) to get (p - q):

(p - q)(x) = (5x^2 - x - 3) - (2x^2 + 4x - 3)

= 5x^2 - x - 3 - 2x^2 - 4x + 3

= (5x^2 - 2x^2) + (-x - 4x) + (-3 + 3)

= 3x^2 - 5x

Now, calculate the inner product of (p - q) with itself using the given inner product formula:

{p - q, p - q} = 5(a1)(a2) + 4(b1)(b2) + 3(c1)(c2)

= 5(3)(3) + 4(-5)(-5) + 3(0)(0)

= 45 + 100 + 0

= 145

Therefore, the value of {p - q, p - q} is 145.

Please calculate the volume of a solid oblique pyramid with a triangular base, given that the base has a length of 8 inches and a height of 6 inches, and the height of the pyramid is 10 inches. Round your answer to the nearest cubic inch.

Answers

Answer: 74

Step-by-step explanation:

The volume of the pyramid can be found using the formula:

Volume = (1/3) x Base Area x Height

To find the base area, we need to find the area of the triangular base. The area of a triangle can be found using the formula:

Area = (1/2) x Base x Height

Substituting the given values, we have:

Area = (1/2) x 8 x 6 = 24 square inches

To find the height of the pyramid, we can use the Pythagorean theorem. The slant height and one-half of the base form a right triangle, so we have:

Height^2 = (Slant Height)^2 - (1/2 x Base)^2

Height^2 = 10^2 - 4^2

Height^2 = 84

Height = √84 ≈ 9.165 inches

Now we can substitute the values into the formula for the volume:

Volume = (1/3) x Base Area x Height

Volume = (1/3) x 24 x 9.165

Volume ≈ 73.96 cubic inches

Therefore, the volume of the pyramid is approximately 73.96 cubic inches.Step-by-step explanation:

A man goes 10m North and turns left and covers 6m. He again turns left and walks 5m. Which direction is he in from starting point?

Answers

The man is in the south direction from the starting point.

Let's visualize the movements of the man step by step:

The man starts by going 10 meters north.

He then turns left (which means he is now facing west) and covers 6 meters in that direction.

Next, he turns left again (which means he is now facing south) and walks 5 meters.

To determine the final direction of the man from the starting point, we can consider the net effect of his movements.

Starting from the north, he moved 10 meters in that direction. Then, he turned left twice, which corresponds to a 180-degree turn, effectively changing his direction by 180 degrees.

Since he initially faced north and then made a 180-degree turn, he is now facing south. Therefore, the direction he is in from the starting point is "south."

Determine the equation of the hyperbola with foci... 100pts

Answers

Answer:

[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]

Step-by-step explanation:

To write the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8), we first need to determine the orientation of the hyperbola.

As the y-values of the foci are the same, the foci are located horizontally from the center of the hyperbola, and therefore the hyperbola is horizontal (opening left and right).

The standard equation for a horizontal hyperbola is:

[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]

where:

center = (h, k)vertices = (h±a, k)foci = (h±c, k) where c² = a² + b²

The center of a hyperbola is the midpoint of the vertices.

Given that the vertices are (-1, -8) and (-11, -8), we can use the midpoint formula to find the coordinates of the center:

[tex](h,k)=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)[/tex]

[tex](h, k)=\left(\dfrac{-1-11}{2},\dfrac{-8-8}{2}\right)[/tex]

[tex](h, k)=\left(-6,-8\right)[/tex]

The value of "a" is the distance between the center of the hyperbola and each vertex.  To find the value of a, calculate the distance between the x-coordinates:

[tex]a=-1-(-6)=5[/tex]

[tex]a=-6-(-11)=5[/tex]

The value of "c" is the distance between the center of the hyperbola and each focus.  Given that the foci are (7, -8) and (-19, -8), and the center is (-6, -8), to find the value of c, calculate the distance between the x-coordinates:

[tex]c = 7-(-6)=13[/tex]

[tex]c = -6-(-19)=13[/tex]

Now we have determined the values of a and c, we can use c² = a² + b² to find the value of b:

[tex]c^2 = a^2 + b^2[/tex]

[tex]13^2 = 5^2 + b^2[/tex]

[tex]169 = 25 + b^2[/tex]

[tex]b^2=144[/tex]

[tex]b=12[/tex]

Finally, substitute the found values of a, b, h and k into the standard equation of a hyperbola:

[tex]\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1[/tex]

[tex]\dfrac{(x-(-6))^2}{5^2}-\dfrac{(y-(-8))^2}{12^2}=1[/tex]

[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]

Therefore, the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8) is:

[tex]\boxed{\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1}[/tex]

Which complex number is equivalent to this expression? 1/3(6+3¡)-2/3(6-12¡)

Answers

So, the complex number equivalent to the given expression is 0 + 9i, which can also be written as 9i.

To simplify the expression 1/3(6 + 3i) - 2/3(6 - 12i), we can perform the necessary calculations.

First, let's simplify each term separately:

1/3(6 + 3i) = 2 + i (divide each term by 3)

2/3(6 - 12i) = 4 - 8i (divide each term by 3)

Now, let's substitute these simplified terms back into the original expression:

2 + i - (4 - 8i)

When subtracting complex numbers, we distribute the negative sign:

2 + i - 4 + 8i

Combine like terms:

(-2 + 2) + (i + 8i) = 0 + 9i

The expression 1/3(6 + 3i) - 2/3(6 - 12i) simplifies to 9i.

We can make the necessary computations to simplify the statement 1/3(6 + 3i) - 2/3(6 - 12i).

Let's first simplify each phrase individually:

Divide each term by 3 to get 1/3(6 + 3i) = 2 + i.

Divide each term by 3 to get 2/3(6 - 12i) = 4 - 8i.

Let's now add these abbreviated terms back into the original phrase:

2 + i - (4 - 8i)

Distributing the negative sign while subtracting complex numbers is as follows:

2 + i - 4 + 8i

combining similar terms

(-2 + 2) + (i + 8i) = 0 + 9i

A simplified version of the phrase 1/3(6 + 3i) - 2/3(6 - 12i) is 9i.

The sum of the measures of the angles is 180. The sum of the measures of the second and third angles is two times the measure of the first angle. The third angle is 20 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.

Answers

Let's solve the given problem step by step using the information provided.

Let's assign variables to the measures of the angles:
Measure of the first angle: X
Measure of the second angle: Y
Measure of the third angle: Z
According to the problem, the sum of the measures of the angles is 180. Therefore, we can write the equation:
X + Y + Z = 180
The problem also states that the sum of the measures of the second and third angles is two times the measure of the first angle. We can express this as an equation:
Y + Z = 2X
Additionally, it is given that the third angle is 20 more than the second angle. This can be expressed as an equation:
Z = Y + 20
Now, we have a system of three equations:

Equation 1: X + Y + Z = 180
Equation 2: Y + Z = 2X
Equation 3: Z = Y + 20

To solve this system, we can substitute Equation 3 into Equation 2 to eliminate Z:
Y + (Y + 20) = 2X
2Y + 20 = 2X
2Y = 2X - 20
Y = X - 10

Now, we have an expression for Y in terms of X. We can substitute this expression into Equation 1 to eliminate Y:
X + (X - 10) + Z = 180
2X - 10 + Z = 180
Z = 190 - 2X

So, we have expressions for Y and Z in terms of X:
Y = X - 10
Z = 190 - 2X

Now, we can substitute these expressions into the original equation for the sum of the measures of the angles to solve for X:
X + (X - 10) + (190 - 2X) = 180
X + X - 10 + 190 - 2X = 180
2X - 2X + X = 180 - 190 + 10
X = 0

Substituting X = 0 back into the expressions for Y and Z, we get:
Y = 0 - 10 = -10
Z = 190 - 2(0) = 190

Therefore, the measures of the angles are:
First angle (X): 0 degrees
Second angle (Y): -10 degrees
Third angle (Z): 190 degrees

Note: It is unusual to have negative angles in a geometric context. Please double-check the problem statement to ensure there are no errors or inconsistencies in the given information.

QUESTION 3: Given: f(x)=1/x-1 -2 3.1 Write down the equation(s) of the asymptote(s) of f. 3.2 Determine the x-intercept of f. ​

Answers

Given the function `f(x)=1/x-1 -2` the task is to write the equation of the asymptote(s) of f and determine the x-intercept of f. Asymptotes are lines that the curve of a function approaches but never touches. There are two types of asymptotes: vertical and horizontal.

Vertical Asymptote Vertical asymptotes occur when a function approaches infinity or negative infinity at a specific value of x. This can occur in a rational function where there is a division by zero.

A vertical asymptote is found when the denominator of the rational function becomes zero. Since division by zero is undefined, it means that the rational function approaches infinity or negative infinity.

The equation of the vertical asymptote is x = a where a is the value that makes the denominator zero.

Horizontal AsymptoteA horizontal asymptote occurs when a function approaches a constant value (y) as x approaches infinity or negative infinity. A horizontal asymptote occurs when the degree of the numerator and denominator is the same.

The horizontal asymptote is found by comparing the degrees of the numerator and denominator and dividing the leading coefficient of the numerator by the leading coefficient of the denominator.3.1 Equation of the asymptotes of the equation of the vertical asymptote is x=1.

The degree of the numerator is less than the degree of the denominator. Therefore, the horizontal asymptote is y=0The equation of the horizontal asymptote is y=0.3.2 X-intercept of fTo find the x-intercept of f, set y=0.f(x) = 0= 1/(x-1) -2Add 2 to both sides2 = 1/(x-1)Take the reciprocal of both sides of the equation.1/2 = (x-1)x-1 = 2x = 3Hence, the x-intercept of the function is (3,0)

Round the final answer to the nearest hundredth.

Answers

Answer:

the effective tax rate for a taxable income of $175,000 is approximately 21.02%.

Step-by-step explanation:

Let's break down the income into the corresponding tax brackets:

The first $10,275 is taxed at a rate of 10%.

Tax on this portion: $10,275 * 0.10 = $1,027.50

The income between $10,276 and $41,175 is taxed at a rate of 12%.

Tax on this portion: ($41,175 - $10,276) * 0.12 = $3,710.88

The income between $41,176 and $89,075 is taxed at a rate of 22%.

Tax on this portion: ($89,075 - $41,176) * 0.22 = $10,656.98

The income between $89,076 and $170,050 is taxed at a rate of 24%.

Tax on this portion: ($170,050 - $89,076) * 0.24 = $19,862.88

The income between $170,051 and $175,000 is taxed at a rate of 32%.

Tax on this portion: ($175,000 - $170,051) * 0.32 = $1,577.44

Now, sum up all the taxes paid:

$1,027.50 + $3,710.88 + $10,656.98 + $19,862.88 + $1,577.44 = $36,836.68

The effective tax rate is calculated by dividing the total tax paid by the taxable income:

Effective tax rate = Total tax paid / Taxable income

Effective tax rate = $36,836.68 / $175,000 = 0.21024 (rounded to the nearest hundredth)

how to find surfes area

Answers

Remember to use the appropriate units for measurements when calculating surface area.

To find the surface area of an object, you need to calculate the total area of all its exposed surfaces. The method for finding the surface area will vary depending on the shape of the object. Here are some common shapes and their respective formulas:

1. Cube: The surface area of a cube can be found by multiplying the length of one side by itself and then multiplying by 6 since a cube has six equal faces. The formula is: SA = 6s^2, where s is the length of a side.

2. Rectangular Prism: A rectangular prism has six faces, each of which is a rectangle. To find the surface area, calculate the area of each face and add them up. The formula is: SA = 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism.

3. Cylinder: The surface area of a cylinder includes the area of two circular bases and the area of the curved side. The formula is: SA = 2πr^2 + 2πrh, where r is the radius and h is the height.

4. Sphere: The surface area of a sphere can be found using the formula: SA = 4πr^2, where r is the radius.

In 2019 the assets are about $1135.4 billion.

How to estimate the cost of the assets in 2011?

Based on the information provided, we can logically deduce that the assets for a financial firm can be approximately represented by the following exponential function:

[tex]A(x)=324e^{0.066x}[/tex]

where:

A(x) is in billions of dollars.x = 7 corresponds to the year 2007.

For the year 2011, the cost (in billions of dollars) is given by;

x = (2011 - 2007) + 7

x = 4 + 7

x = 11 years.

Next, we would substitute 11 for x in the exponential function:

[tex]A(11)=324e^{0.066 \times 11}[/tex]

A(11) = $669.6 billions.

Part b.

For the year 2016, the cost (in billions of dollars) is given by;

x = (2016 - 2007) + 7

x = 9 + 7

x = 16 years.

Next, we would substitute 16 for x in the exponential function:

[tex]A(16)=324e^{0.066 \times 16}[/tex]

A(16) = $931.5 billions.

Part c.

For the year 2019, the cost (in billions of dollars) is given by;

x = (2019 - 2007) + 7

x = 12 + 7

x = 19 years.

Next, we would substitute 19 for x in the exponential function:

[tex]A(19)=324e^{0.066 \times 19}[/tex]

–5 < 2x – 1 < 3 solve?? help aap

Answers

Answer:

Step-by-step explanation:

To solve the inequality -5 < 2x - 1 < 3, we will break it down into two separate inequalities and solve each one individually.

First, let's solve the left inequality:

-5 < 2x - 1

Add 1 to both sides:

-5 + 1 < 2x - 1 + 1

-4 < 2x

Divide both sides by 2 (remembering to reverse the inequality when dividing by a negative number):

-4/2 < 2x/2

-2 < x

Now, let's solve the right inequality:

2x - 1 < 3

Add 1 to both sides:

2x - 1 + 1 < 3 + 1

2x < 4

Divide both sides by 2:

2x/2 < 4/2

x < 2

So, the solutions to the inequalities are:

-2 < x < 2

This means that x is greater than -2 and less than 2.

[tex] \frac{1}{( - 7)^{4} } [/tex]

Answer:

[tex](-7)^-^4=\frac{1}{(-7)^4}[/tex]

Step-by-step explanation:

The user aswati already wrote the correct answer, but I wanted to help explain why their answer is correct so that you'll understand.

According to the negative exponent rule, when a base (let's call it m) is raised to a negative exponent (let's call it n), we rewrite it as a fraction where the numerator is 1 and the denominator is the base raised to the same exponent turned positive.

Thus, the negative exponent rule is given as:

[tex]b^-^n=\frac{1}{b^n}[/tex]

Thus, [tex](-7)^-^4[/tex] becomes [tex]\frac{1}{(-7)^4}[/tex]

f(4)
f(x)=2x+1
f(4)=2(4)+1

this one is easy to get, but i'm not too sure how to put it on the first one...

Answers

Answer:

Step-by-step explanation:

To format and solve the equation "f(x) - 4" with the given function "f(x) = 2x + 1," we substitute the function into the equation and solve for x. Here's how it can be done:

f(x) - 4 = 2x + 1 - 4

Simplifying further:

f(x) - 4 = 2x - 3

To answer the question "f(4)" using the function f(x) = 2x + 1, we substitute x = 4 into the function:

f(4) = 2(4) + 1

Simplifying further:

f(4) = 8 + 1

f(4) = 9

Therefore, the value of f(4) is 9 when using the function f(x) = 2x + 1.

Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.
Step 1: m = StartFraction 13 minus 25 Over negative 4 minus (negative 7) EndFraction = StartFraction negative 12 Over 3 EndFraction = negative 4. Step 2: y = negative 4 x + b. 25 = negative 4 (negative 7) + b. 25 = 28 + b. 25 minus 28 = 28 + b minus 28. b = negative 3. Step 3: y = negative 3 x minus 4


What was Brooke’s error?
She found the incorrect slope in step 1.
She mixed up the x- and y-coordinates when she plugged in the point in step 2.
She found the incorrect y-intercept in step 2.
She mixed up the slope and y-intercept when she wrote the equation in step 3

Answers

Answer:

she mixed up the slope and y- intercept in step 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

she correctly calculated the slope as m = - 4 and the y- intercept b = - 3

thus equation she should have is

y = - 4x - 3

Brooke's error was that she found the incorrect slope in step 1.  

The slope formula is:  m = (y₂ - y₁) / (x₂ - x₁)  

Using the given points:  m = (13 - 25) / (-4 - (-7))  m = -12 / 3  m = -4  

So, the slope is -4, not -12/3 as Brooke calculated in step 1.  

The correct equation for the line passing through the points (-7, 25) and (-4, 13) is: y = -4x - 3 (as found in step 3)

Answer: -5/4

Step-by-step explanation:

To find the slope between two points, you can use the formula:

Slope = (y2 - y1)/(x2 - x1)

Using the points (0, -1) and (-4, 4), we can substitute the coordinates into the formula:

slope = (4 - (-1))/(-4 - 0)

slope = (4 + 1)/(-4)

slope = 5/-4

Therefore, the slope between the two points is -5/4.
