Suppose that $500 is invested at the end of every year for 5 years. The polynomial function that models the value of the investment is P(x) = 500x5 +500x² +500x³ +500x² + 500x, where x represents the effective interest rate plus 100%. One year after the last payment, the investment is worth $3200. Find the effective interest rate one year after the last payment, to the nearest tenth. (Note: You will need to subtract 1 from the value of x to find the effective interest rate.)

You purchased a bond with a face value of $5,000 five years ago for $4,750. The bond pays a coupon rate of 4%, paid every 2 months (6 times a year). If you want an annual yield of 6% from the bond, how much should you sell the bond for now?  Question 6 Part B: Identify the correct Function Notation for this scenario.

Compute the present value if future value (FV) = $6127, interest rate (r) = 8.2%, and number of years (t) = 13.

Would love the help.
