Find the equation. (which I did) -- x^2 = 8y

If the dish is 8 feet wide, how deep is it?

**Damon**, Tuesday, December 20, 2011 at 8:28pmso x = +/- 4 if 8 wide

what is y ?

16 = 8 y

y = 2

**lindsey**, Tuesday, December 20, 2011 at 8:30pmWow. Do I just substitute x with 8, and then solve to get y=5?

**Lindsey**, Tuesday, December 20, 2011 at 8:30pmOops nevermind, sorry.

**Damon**, Tuesday, December 20, 2011 at 8:32pmNo, x is half the width.
