Answer:
99 038.52 USD
Step-by-step explanation:
In order to solve this question we have to use the compound interest formula
A = P*(1+i)ˆn
A: final amount including principal
P: principal amount
i: interest per year
n: total number of years
A = 40000 (1+0.12)ˆ8
A = 99 038.52 USD
16.875=ab^3 (divided by what follows)
7.5=ab^1 gives you:
2.25=b^2
b=1.5 now we can solve for a...
7.5=a(1.5^1), a=5 so the function is:
y=5(1.5^x)
