A$22,000 deposit at an apr of 5.1% with a quarterly compounding for 25 years. after 25 years will be

After 25 years the amount will be $78099.34.

Step-by-step explanation:

The compound interest formula is ;

Where p = 22000

r = 5.1% or 0.051

n = 4

t = 25

So, putting the values in formula we get;

A = $78099.34

Therefore, after 25 years the amount will be $78099.34.

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,
