**Problem Statement:**

Find the annual percentage yield for an investment at the following rates. (Round your answers to two decimal places.)

**(a)** 6.3% compounded monthly  
[Input Box] %

**(b)** 9% compounded continuously  
[Input Box] %

**Explanations:**

In part (a), you are required to find the annual yield for a 6.3% interest rate that is compounded monthly. To calculate this, use the formula for annual percentage yield (APY) with monthly compounding:

\[ 
APY = \left(1 + \frac{r}{n}\right)^n - 1 
\]

where \( r \) is the annual nominal interest rate (0.063 for 6.3%) and \( n \) is the number of compounding periods per year (12 for monthly).

In part (b), you need to calculate the annual yield for a 9% interest rate compounded continuously. Use the formula for continuous compounding:

\[ 
APY = e^r - 1 
\]

where \( e \) is the base of the natural logarithm (approximately 2.71828) and \( r \) is the annual nominal interest rate (0.09 for 9%).

Both answers should be rounded to two decimal places and entered in the provided input boxes.
