To solve this problem, we can set up a system of equations based on the given information.

Let's assume the amount of money Ralph Chase will receive through the short-term note is represented by "x" and the amount through the long-term note is represented by "y".

According to the problem, the total amount Ralph plans to sell the property for is $145,000. Therefore, we have the equation:

[tex]\displaystyle x+y=145000[/tex] ...(1)

Now let's consider the interest paid annually. The interest paid on the short-term note at 10% is calculated as [tex]\displaystyle 0.10x[/tex], and the interest paid on the long-term note at 8% is [tex]\displaystyle 0.08y[/tex]. The total annual interest paid is given as $13,100. Therefore, we have the equation:

[tex]\displaystyle 0.10x+0.08y=13100[/tex] ...(2)

We now have a system of two equations (1) and (2). We can solve this system to find the values of "x" and "y".

Multiplying equation (2) by 100 to eliminate decimals, we get:

[tex]\displaystyle 10x+8y=1310000[/tex] ...(3)

Now we can solve equations (1) and (3) simultaneously using any method such as substitution or elimination.

Multiplying equation (1) by 10, we get:

[tex]\displaystyle 10x+10y=1450000[/tex] ...(4)

Subtracting equation (3) from equation (4), we can eliminate "x" and solve for "y":

[tex]\displaystyle 2y=140000[/tex]

Dividing both sides by 2, we find:

[tex]\displaystyle y=70000[/tex]

Now substituting the value of "y" back into equation (1), we can solve for "x":

[tex]\displaystyle x+70000=145000[/tex]

Subtracting 70000 from both sides, we have:

[tex]\displaystyle x=75000[/tex]

Therefore, the amount of money Ralph Chase will receive through the short-term note is 75,000 and through the long-term note is $70,000.

Answer: c. known

Step-by-step explanation:

In random sampling, the probability of selecting an item from the population is known. This probability can be calculated based on the sampling method and the characteristics of the population being sampled. Random sampling ensures that each item in the population has an equal chance of being selected, making the probability of selection known and calculable.

Answer:

Step-by-step explanation:

When the equation is in the slope intercept form of y = mx + b, you know that the m is the slope and the b is the y-intercept (0, b)

By looking at the equation  y=2x + 2, you can determine that the y-intercept will be at the point (0, 2)  and the slope is 2.

To graph, start with the point of (0, 2) then go up 2 units and to the right 1 unit.  So the next point will be at (1, 4)

You can also, substitute and number in for the x and calculate the y value.   For example, if x is 3, then  y=2(3)+2; y = 8 so the point (3, 8) is on the line.

Answer:

Step-by-step explanation:

The correct domain for the function y = √x is 0 ≤ x < ∞. The square root function is defined for non-negative real numbers, so x must be greater than or equal to 0 (0 ≤ x) to have a real value for the square root. The domain does not include negative values since the square root of a negative number is not a real number. The notation 0 ≤ x < ∞ represents all values of x that are greater than or equal to 0 and less than positive infinity.

The estimated population of the state in the year 2022 is 19,280,700 people.

The given equation represents the population of a certain state as a function of time, where p is the population in thousands of people and t is the number of years since 2010.

The equation is given as p = 80.7t + 18,312.3.

To estimate the population of the state, we substitute the value of t into the equation. For example, if we want to estimate the population in the year 2022 (12 years since 2010), we substitute t = 12 into the equation:

p = 80.7(12) + 18,312.3

= 968.4 + 18,312.3

= 19,280.7.

The estimated population of the state in the year 2022 is 19,280,700 people.

We can estimate the population for any given year by substituting the corresponding value of t into the equation.

It's important to note that the population is given in thousands of people, so we multiply the final result by 1,000 to obtain the population in actual numbers.

Part A: The interest earned if the interest is compounded quarterly is $2,768.40.

Part B: The interest earned if the interest is compounded continuously is $2,695.92.

Part C: The difference in the amount of interest earned is approximately $72.48.

Part A: To calculate the interest earned when the interest is compounded quarterly, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

Where:

A = the final account balance

P = the principal amount (initial investment)

r = the annual interest rate (4.75% or 0.0475 as a decimal)

n = the number of times the interest is compounded per year (4 times for quarterly)

t = the number of years (42 months divided by 12 to convert to years)

Plugging in the values:

A = $15,000(1 + 0.0475/4)^(4 * (42/12))

A = $15,000(1.011875)^(14)

A ≈ $15,000(1.18456005)

A ≈ $17,768.40

The interest earned is the difference between the final account balance and the principal amount:

Interest earned = $17,768.40 - $15,000

Interest earned ≈ $2,768.40

Part B: When the interest is compounded continuously, we can use the formula:

[tex]A = Pe^(^r^t^)[/tex]

Where:

A = the final account balance

P = the principal amount (initial investment)

e = the mathematical constant approximately equal to 2.71828

r = the annual interest rate (4.75% or 0.0475 as a decimal)

t = the number of years (42 months divided by 12 to convert to years)

Plugging in the values:

A = $15,000 * e^(0.0475 * 42/12)

A ≈ $15,000 * e^(0.165625)

A ≈ $15,000 * 1.179727849

A ≈ $17,695.92

The interest earned is the difference between the final account balance and the principal amount:

Interest earned = $17,695.92 - $15,000

Interest earned ≈ $2,695.92

Part C: Comparing the interest earned for each account, we find that the interest earned when the interest is compounded quarterly is approximately $2,768.40, while the interest earned when the interest is compounded continuously is approximately $2,695.92.

The period of the trigonometric function is -2π/3.

To determine the period of the trigonometric function based on the given information, we need to consider the pattern of the graph and identify the interval over which it repeats.

Given that the maximum point is at (-π, 7.7) and the minimum point is at (-1/3π, -6.7), we can observe that the graph completes one full oscillation between these two points.

The distance between the maximum and minimum points corresponds to half of the period. Therefore, the full period of the function can be found by doubling this distance.

The distance between (-π, 7.7) and (-1/3π, -6.7) can be calculated as follows:

Δx = -1/3π - (-π) = π/3π - π = -π/3

Since the full period is twice this distance, we multiply by 2:

2 * (-π/3) = -2π/3

Answer:

x = 2

Step-by-step explanation:

We are given the following equation:

[tex]\sqrt{x+7} -1=x[/tex], which we want to solve for x.

To do this, we should isolate the square root on one side, then square both sides. We can then solve the equation as normal, but then we have to check the domain in the end for any extraneous solutions.

Start by adding 1 to both sides.

[tex]\sqrt{x+7} -1=x[/tex]

            +1      +1

________________________

[tex]\sqrt{x+7} = x+1[/tex]

Now, square both sides.

[tex](\sqrt{x+7} )^2= (x+1)^2[/tex]

We get:

x + 7 = x² + 2x + 1

Subtract x + 7 from both sides.

x + 7 = x² + 2x + 1

-(x+7)   -(x+7)

________________________

0 = x² + x - 6

This can be factored to become:

0 = (x+3)(x-2)

Solve:

x+3 = 0

x = -3

x-2 = 0

x = 2

We get x = -3 and x = 2. However, we must check the domain.

Substitute -3 as x and 2 as x into the original equation.

We get:

[tex]\sqrt{-3+7} -1 = -3[/tex]

[tex]\sqrt{4} -1 = -3[/tex]

2 - 1 = -3

-1 = -3

This is an untrue statement, so x = -3 is an extraneous solution.

We also get:

[tex]\sqrt{2+7} -1 = 2[/tex]

[tex]\sqrt{9}-1=2[/tex]

3 - 1 = 2

2 = 2

This is a true statement, so x = 2 is a real solution.

Our only answer is x = 2.

The range for the graph provided is from -10 to 10, inclusive.

To determine the range of the graph, we look at the vertical values or the y-values. The lowest y-value on the graph is -10, which corresponds to the point (-6, -10). The highest y-value on the graph is 10, which corresponds to the point (6, 10).

Therefore, the range of the graph is from -10 to 10, which means that all the y-values on the graph fall within this range. This indicates that the graph spans a vertical distance of 20 units, starting from -10 and ending at 10.

It's important to note that the range includes the minimum and maximum values attained by the graph. In this case, the graph reaches its lowest point at -10 and its highest point at 10.

Also, for x =0 we have:

y = 15*sin(0/2) = 0

y = 0

So the fourth graph can be discarded.

Also, when x increases also does the function (near x = 0), so the third graph is discarded.

Finally, sin(pi) = 0, in this case when x = 2pi we will get:
