Tricia invested $8500 at 3% interest compounded annually. how much interest will she earn in 3 years a.$255.00 b.$788.18 c.$9288.18 d.$10,174.50

Choice C) $9288.18

She has P = 8500 dollars to deposit for t = 3 years and it's compounded n = 1 times per year. So this means the final amount A is...

A = P*(1+r/n)^(n*t)

A = 8500*(1+0.03/1)^(1*3)

A = 8500*(1.03)^3

A = 8500*(1.092727)

A = 9288.1795

A = 9288.18

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
