Tina wants to save money for school tina invests $1,200 in an that pays an interest rate of 6.25%
how many years will it take for the account to reach $11,900? round to the nearest hundredth.

37.84 years

Step-by-step explanation:

We apply the compound interest formula;

A = P(1+r)^n

In this case we have;

A = 11,900

P = 1,200

r = 6.25% p.a

We substitute these values into the above equation and solve for n, the number of years required.

11900 = 1200(1.0625)^n

9.91667 = 1.0625^n

n = 37.84 years

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,
