The equation for this is:

F = P(1+i)ⁿ
where
F is the present accounts balance
P is the initial deposit
i is the interest rate
n is the number of months

The interest rate is nominal which is 2.9% per year compounded monthly. Since there are 12 months in a year, that is equal to an effective interest rate of 0.24167% per month compounded monthly (i = 0.0024167). In 9 years, there are a total of 108 months, so n=108.

Answer:

c. -17

Step-by-step explanation:

We have the function f(x) = -2t^2 + 1 and we need to solve for x if f(-3).

Substitute the x in the function with the x in the equation :

f(-3) = -2(-3)^2 + 1

Solve for the answer :

f(-3) = -2(9) + 1

f(-3) = -18 + 1

f(-3) = -17

Therefore, c. -17 is the answer.
