Answer:
y = 9/b
Step-by-step explanation:
by = 9 solved for b yields y = 9/b.
Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r =
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 ×
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
You do 5.5x4=22, so you can drive 22 miles for every gallon of gas.
