George’s parents are saving for his college fund. They put $5,000 into an interest bearing account with a compound interest rate of 5.5%. George’s parents want to determine what the balance of his college fund account will be after 15 years. Using the formula A = P (1 + r) Superscript t, which is the correct substitution for the formula?

see below

Step-by-step explanation:

A = P (1 + r) ^t

A is the amount in the account

P is the principle or the amount invested

r is the interest rate

t is the time

A = 5000 (1 + .055)^15

     5000(2.23247)

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,

correct answer:

b.(19,-2)
