1. Determine the interest rate / needed for an investment to quadruple in value in 2 years if interest is compounded continuously. Exact interest rate (without using a calculator), r = (Exact answerot in decimal form) Interest rate, as a percent, rounded to 2 decimal places = 2. How long will it take for $3,000 to grow to $9,000 if the investment earns an interest rate of 12% per year compounded quarterly (i.e., 4 times a year). Exact length of time (without using a calculator), t = (Exact answerot in years decimal form) Length of time, rounded to 2 decimal places =[ years 3. How long does it take for an investment earning interest at a rate of 3% compounded monthly (i.e., 12 times a year) to quadruple in value? Exact length of time (without using a calculator), + = years (Exact answerot in decimal form) Length of time, rounded to 2 decimal places = years 4. How long will it take for $4,000 to grow to $8,000 if the investment earns an interest rate of 5% per year compounded continuously. Exact length of time (without using a calculator), t = (Exact answerot in years decimal form) Length of time, rounded to 2 decimal places = years 5. How long does it take for an investment earning interest at a rate of 8% compounded continuously to double in value? Exact length of time (without using a calculator), t = Exact answerot in years decimal form) Length of time, rounded to 2 decimal places =[ years 6. Find the effective interest rate corresponding to a nominal interest rate of 16% compounded quarterly. (Exact answerot in Effective interest rate (without using a calculator), reff = decimal form) Effective interest rate, as a percent, rounded to 2 decimal places = 7. (a) Compute the effective interest rate corresponding to a nominal interest rate of 12% compounded semiannually. Effective interest rate, as a percent, rounded to 4 decimal places =[ % (b) Compute the effective interest rate corresponding to a nominal interest rate of 11.76% compounded daily. Effective interest rate, as a percent, rounded to 4 decimal places =[ (c) Select the investment that offers the better return. 12% compounded semiannually 11.76% compounded daily
