from 2002 to 2012, the number of a particular make of cars sold at a dealership yearly declined to 500. The number is expected t

Alinara [238K]

To determine the number of cars that will be sold by the year 2020, we will use the equation,

N = (N1)(1 - r)^(t)

where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,

N = (500)(1 - 0.028)^(8)
N = 398.38

The closest integer to the calculated value is 398. Thus, the answer is 398 cars.

Area= Help me please!! Thanks :)

Answer:

80π

Step-by-step explanation:

Circle O with radius IO:

large radius = IO = 12 = R

Circle O with diameter JK

IJ = JK = KL = 2 × IO = 24

IJ = JK = KL = 24/3 = 8

small radius = 8/2 = 4 = r

The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.

That is the same as

1 semicircle of radius 12 plus 1 semicircle of radius 4

A = πR²/2 + πr²/2

A = π(12² + 4²)/2

A = 160π/2

A = 80π

jenny borrowed $500 for 5 years at 4% interest compounded annually. what is the total amount she will have paid when she pays of

alexdok [17]

Use the formula for compound interest,

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

Where P is the starting amount (500$), r is the rate of interest (0.04), n is the number of times the interest is compounded per unit (1 per year), and t is the amount of time it is compounded (5 years).

Now, plug it into the formula:

$A=500(1+ \frac{0.04}{1})^{5}$

Do the math, and your answer is she must pay 608.32$ when she pays her debts.
