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)^t , which is the correct substitution for the formula? a=5000(1+0.055)^15 a=5000(1+0.055)15 a=5000(1+0.055)^5.5 a=(5000+0.055)+1^15

Step-by-step explanation:

Given : George’s parents put $5,000 into an interest bearing account with a compound interest rate of 5.5%.

i.e. Principal amount :

Rate of interest : r=5.5%=0.055

George’s parents want to determine what the balance of his college fund account will be after 15 years. i.e. t= 15

Substitute all the values of p , r at t in the given formula , we get

Hence, the correct substitution for the formula =

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
