A person places $82100 in an investment account earning an annual rate of 4.3%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 2 years. WILL GIVE IF CORRECT!!

I was taught compound interest this way hopefully it helps.

100 + interest rate / 100 = multiplier

100 + 4.3 = 104.3. 104.3/100 = 1.043

Amount X multiplier to the power of time

82100 X 1.043^2 = 89312.4029

as it is a monetary unit round to 2dp

$89312.40

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer is 33
