Answer:

r = 75 mi; A = 17 671 mi²

Step-by-step explanation:

(a) Graph

The equation for a circle is

x² + y² = r²

Your equation is

x² + y² = 5625 = 75²

The graph is a circle with a radius of 75 mi.

(b) Broadcast area

A = πr² = π × 75² = π × 5625 ≈ 17 671 mi²

I did not catch well, but i think you already got your answers. Let me explain. For the first part you got your notation right: for 0.0045 the correct scientific notation is 4.5 x 10^-3. Now the second part, the answer would be the first one, the notation that you are giving is the one who corresponds to <span>4.5 x 10^-2, the first option you have. Hope it helps</span>

Money is invested into an account earning 4.25% interest compounded annually. If the accumulated value after 18 years will be $2
Lunna [17]
We are given with the following:
Effective annual interest, i = 0.0425
Future worth, F = $25000
Number of years, n = 18

We use the formula to solve for the present worth of the money:
P = F / (1 + i)^n
P = 25000 / (1 + 0.0425)^18
P = 11818.73
