can you answer the following:

1.A zero-coupon bond is a security that pays no interest, and is therefore bought at a substantial discount from its face value. If stated interest rates are 5% annually (with monthly compounding) how much would you pay today for a zero coupon bond with a face value of $1,900 that matures in 8 years?

2. A financial institution offers a "double-your-money" savings account in which you will have $2 in 5 years for every dollar you invest today. What stated annual interest rate (assuming quarterly compounding) does this account offer? Please specify your answer in decimal terms and round your answer to the nearest thousandth (e.g., enter 12.3 percent as 0.123).

3. You have $50,000 in savings for retirement in an investment earning a stated annual rate of 4% compounded quarterly. You aspire to have $1,000,000 in savings when you retire. Assuming you add no more to your savings, how many years will it take to reach your goal?

Please round your answer to the nearest hundredth.

4.

You deposit $1,700 in a bank account that pays 7% stated annual interest compounded continuously. What is the value of your investment at the end of 9 years? Please round your answer to the nearest cent.

Please round your answer to the nearest cent.
