Answer:

-$860

-58.64%

Step-by-step explanation:

Given the cash price as $2200, the down payment as $500 and monthly installments of $320 for 8 months, the interest charged is calculated as;

$Interest=Hire \ Purchase \ Price -Cash \ Price\\\\=(500+320\times8)-2200\\\\=3060-2200\\\\=860$

Hence, the interest charged is $860

#Flat rate of interest is similar to simple interest rate.

Knowing n=8 months and interest as $860, the rate is calculated as:

$I=P\times i \times n \ \ \ \ \n=8/12 \ ,P=2200\\\\860=2200i\times \frac{8}{12}\\\\i=0.5864$

Hence, the flat rate of interest over the 8 months is 58.64%

A rocket is launched into the air. The height h(t), in yards, of the rocket is a function of time, t, in seconds, as shown in th

Vesna [10]

Answer:

Step-by-step explanation:

Average rate of change is the same thing as the slope. Because this is parabolic, we cannot find the exact rate of change as we could if this were a linear function. But we can use the same idea. When t = 3, h(t) = 33, so the coordinate point is (3, 33). When t = 6, h(t) = 0, so the coordinate is (6, 0). Plug those values into the slope formula:

$m=\frac{0-33}{6-3}$ and

$m=\frac{-33}{3}$ which is -11

From 3 to 6 seconds, the rocket is falling 11 yards per second.

The formula I = PRT is used to calculate the amount of simple Teresa earned. Solve this formula for T

Dmitrij [34]

To solve this formula for T, divide both sides of the original equation by PR:

I PRT

------ = --------- => T = I / (PR)

PR PR

Please note: Because the formula I = PRT involves neither addition nor subtraction, the final formula for T cannot involve either addition nor subtraction. That leaves:

T = I P/R

T= IPR

The second formula here is incorrect; we cannot solve I = PRT for T simply by rearranging the order of the variables. This leaves T = I P/R as a possible answer, but this answer does not agree with my T = I / (PR). Please double check to ensure that you have copied down the four possible answers correctly.
