Question 1037089: A giant parabolic dish has a diameter of 400 meters and a depth of 80 meters. find an equation in the form that describes a cross section of this dish.
if the receiver is located at the focus, how far should it be from the vertex? Answer by josgarithmetic(39620) (Show Source):
You can put this solution on YOUR website! Cross section is a parabola shape. Imagine the vertex at the Origin, and this vertex as a minimum.
Radius is half of the diameter, being radius of 200. "Depth" becomes there distance of 80 meters. This is a cartesian point, (200,80). Standard Form can start as , the two 0 values because the vertex is (0,0), the Origin as picked here. This more simply is .
Use the point on the rim of the cross section to find coefficient, a.

Finished equation for the cross section is .
