Answer: 
Step-by-step explanation:
For this exercise you must use the followinG Trigonometric Identity:
In this case, given the right triangle PQR, you can identify that:
Then, the next step is to substitute those values into :
And the final step is to solve for "QR" in order to find its value.
So you get that this is:
If we have a common ratio every set amount of time (and not a common difference or addition), this is an exponential relationship. An exponential equation would have a form like Money = (1000)(2)^(# of months), where every additional month would cause the money amount to double.
