2. $A= \frac{r^2\pi\alpha}{360^o}$
3. $l= \frac{r\pi\alpha}{180^o}$
4. $A=ab,P=2(a+b)$
5. $C=2r\pi$
6. $A=r^2\pi$
7. $P=na,S_n=(n-2)180^o,\alpha= \frac{S_n}{n}$

A person places $4080 in an investment account earning an annual rate of 5.7%, compounded continuously. Using the formula

tangare [24]

We have been given that a person places $6340 in an investment account earning an annual rate of 8.4%, compounded continuously. We are asked to find amount of money in the account after 2 years.

We will use continuous compounding formula to solve our given problem as:

, where

A = Final amount after t years,

P = Principal initially invested,

e = base of a natural logarithm,

r = Rate of interest in decimal form.

Upon substituting our given values in above formula, we will get:

Upon rounding to nearest cent, we will get:

Therefore, an amount of $7499.82 will be in account after 2 years.
