Convert r = 8cos θ to rectangular form.

D

to convert from polar to rectangular form use

• cosΘ =

• r² = x² + y²

r = 8 × ( multiply both sides by r )

r² = 8x, hence

x² + y² = 8x ← in rectangular form

D. x² + y² = 8x

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
