Answer:

$7,987.64

Step-by-step explanation:

We know,

A = Pe^(rt)

Here,

A = 11000

interest r = .08

Time t = 4

Now,

11000 = Pe^(.08 * 4)

Or, 11000 = Pe^.32

Or, 11000 / e^.32 = P

Or, 7987.6394 = P

Or, P= 7,987.64

Jerome will have to ask for $7,987.64 to his parents.

What happens to the value?

Fiesta28 [93]

Answer:

D.) c is multiplied by 4

Step-by-step explanation:

$c = \dfrac{8a^3}{b}$

If a is doubled, it becomes 2a. If b is doubled, it becomes 2b. Now we replace a with 2a and b with 2b and simplify.

$c = \dfrac{8(2a)^3}{2b}$

$c = \dfrac{8 \times 8a^3}{2b}$

$c = \dfrac{4 \times 8a^3}{b}$

$c = 4 \times \dfrac{8a^3}{b}$

Answer: D.) c is multiplied by 4
