Answer 1

do you know what the formula is?

Answer 2

sort of

Answer 3

could you put it on here

Answer 4

A=Pe^rt

Answer 5

probably

Answer 6

4000=2500e^r5 then solve

Answer 7

for part C use the value you found for r in part A in this equation x=2500e^r10 then solve for x

Answer 8

parts B and D use different formulas that I don't know off the top of my head
