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

the missing leg length is 2√70.

Step-by-step explanation:

This is a right triangle in which the hypotenuse is 19 ft and one of the legs is 9 ft.  Using the Pythagorean Theorem, we find the length of the other leg:

x^2 = (19 ft)^2 - (9 ft)^2 = 361 - 81 = 280, or 4*70

Then the missing leg length is √4√70, or 2√70.
