Homework Help: Math

Posted by Gabby on Thursday, April 12, 2012 at 3:02am.

In a factory, a parabolic mirror to be used in a searchlight was placed on the floor. It measured 40 centimeters tall and 90 centimeters wide. Find the equation of the parabola.

I tried working this problem out and I got y=-8/405x^2+40, but I'm not sure if it is right. Could someone please help me?
