Answer:

$22.12
$24.51

Step-by-step explanation:

For some growth factor f each year, the growth factor over 20 years is given as ...

f^20 = 1 +0.51 = 1.51

Then the growth factor in 10 years is ...

f^10 = (f^20)^(1/2) = √1.51 ≈ 1.22882

a) In the 10 years between 1998 and 2008, the price of a basic haircut would rise to ...

$18 × 1.22882 ≈ $22.12 . . . price in 2008

b) In the 10 years between 2003 and 2013, the price of a basic haircut would rise to ...

$19.95 × 1.22882 ≈ $24.51 . . . price in 2013

a cross-section is taken parallel to the bases of a general cylinder and has an area of 18. If the height of the cylinder is H, what is the volume of the cylinder? Explain your reasoning.

Answers

∵ the cross-section is parallel to the bases of the cylinder, then it is congruent to the bases thus, the area of the base of the cylinder is 18.
The volume of a general cylinder is the product of the area of the cylinder’s base times the height of the cylinder,
So the volume of the general cylinder is = 18 H

You are borrowing $4,285 to purchase a computer using a 36 month installment plan. Determine the annual percentage rate (APR) and the monthly payment given that the interest charge is $513.26. Round your answer to the nearest whole percent and to the nearest cent.

Answers

The price of the computer is 4 285 dollars which you borrowed for an installment plan.
Let's solve for the APR and the monthly payment.
The interest charge is 513.26 dollars for 36 months
=> 36 months = 3 years
=> 513.26 / 3 years = 171.1 dollars per year is the interest.

=> 4 285 + 513.26 = 4 798.26 dollars
=> 4 798.26 dollars /3 years = 1599.42 dollars per year
=>599.42 dollars / 12 months 133.29 dollars per month
