point(s) possible Someone invests $3090 in an account at 8% interest compounded annually. Let f (t) be the value (in dollars) of the account at t years after she has invested the $3090. a. Find an equation of f. f(t) = b. What is the base b of your model f(t) = ab? What does it mean in this situation? O A. The account balance does not change. OB. The account balance increases by $3090. OC. The account balance increases by 8% per year. O D. The account balance decreases by 8% per year. c. What is the coefficient a of your model f(t) = ab? What does it mean in this situation? OA. The account balance increases by 8% per year. OB. The final amount in the account after t years was $3090. OC. The initial amount in the account was $3090. O D. The account balance decreases by 8% per year. d. What will be the account's value in 13 years? (Type an integer or decimal rounded to the nearest cent as needed.) C Time Remaining: 00:22:43 Ne
