I'd appreciate the formulas

10. Finding the interest rate and the number of years The future value and present value equations also help in finding the interest rate and the number of years that correspond to present and future value calculations. If a security of $4,000 will be worth $7,049 five years in the future, assuming that no additional deposits or withdrawals are made, what is the implied interest rate the investor will earn on the security? 9.00% O 9.60% 12.00% 14.40% for this investment to grow to a If an investment of $45,000 is earning an interest rate of 13.00% compounded annually, it will take value of $73,371.31-assuming that no additional deposits or withdrawals are made during this time? Which of the following statements is true, assuming that no additional deposits or withdrawals are made? It takes 14.2 years for $500 to double if invested at an annual rate of 5%. It takes 10.5 years for $500 to double if invested at an annual rate of 5%. 11. Semiannual and other compounding periods Semiannual compounding implies that interest is compounded times per year. You have deposited $3,750 into an account that will earn an interest rate of 8% compounded semiannually. How much will you have in this account at the end of eight years? $8,428.42 $7,023.68 $8,077.23 $4,565.39
