Question:

Graph the parabola. Give the domain, range, vertex, and axis of symmetry.

A radio telescope has a diameter of 100 ft and a maximum depth of 15 ft.

(a) Write an equation of a parabola that models the cross section of the dish if the vertex is placed at the origin and the parabola opens up.

(b) The receiver must be placed at the focus of the parabola. How far from the vertex, to the nearest tenth of a foot, should the receiver be located?
