Use the Table below to find the Average Rate of Change from x = -2 to x = 1. Show your work for full credit.

sergey [27]

Answer:

We conclude that:

The average rate = -1

Step-by-step explanation:

We need to find the Average Rate of Change from x = -2 to x = 1.

From the table it is clear that:

at x₁ = -2, f(x₁) = 3

at x₂ = 1, f(x₂) = 0

The formula to determine the average rate of change from x = -2 to x = 1.

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

= [0 - 3] / [1-(-2)]

= -3 / 3

= -1

Therefore, we conclude that:

The average rate = -1

Michael obtains a 30/8 balloon mortgage to finance $425,500 at 6.55%. How much principal and interest will he have already paid

STALIN [3.7K]

Answer:

$259 532

Step-by-step explanation:

Step 1. Calculate the monthly payments on a 30-year loan.

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate

of r % is

$P = A(\frac{r}{1-(1+r)^{-n}})$

Data:

We must express the interest rate on a monthly basis.

i = 6.55 %/yr = 0.545 83 %/mo = 0.005 4583

A = $425 500

n = 360 mo

Calculation:

$P = 425 500(\frac{0.005 4853}{1-(1+0.005 4583)^{-360}})$

$P = \frac{2332.22}{{1- {1.005 4583}}^{-360}}$

$P = \frac{2332.52}{1 – 0.140907}$

$P = \frac{2332.52}{0.859 093}$

P = $2703.46

B. Total Payment (T) after 8 years

T = nP

T = 96 × 2703.46

T = $259 532

Michael will have paid $259 532 at the end of eight years.

A bowling alley charges its customers an hourly rate to bowl plus shoe rental. The hourly rates are per lane. A linear model of

emmainna [20.7K]

Answer:

The rate of change for the linear model = 15.25

Step-by-step explanation:

Given:

A linear model where $x$ represents number of hours bowled on one lane and $y$ represents the total cost of bowling.

$(2,34)$

This point shows that the cost of bowling for 2 hours = $34

$(3,49.25)$

This point shows that the cost of bowling for 3 hours = $49.25

To find the rate of change in the given model we need to find the slope of the line $m$ using the given points.

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{49.25-34}{3-2}$

$m=\frac{15.25}{1}$

$m=15.25$

∴ the rate of change for the linear model = 15.25

This shows that the bowling alley charges its customers an hourly rate of $15.25.
