Question 1114351: A satellite dish is shaped like a paraboloid of revolution. This means that it can be formed by rotating a parabola around its axis of symmetry. The receiver is to be located at the focus. If the dish is 36 feet across at its opening and 3 feet deep at its center, where should the receiver be placed?

Vertex as the origin, concave upward.
Two points other than (0,0) are (-18,3) and (18,3), unit being feet.
-
OR equivalently
Let p be distance above the vertex to put the receiver (placement of the focus).
