Scientists studying dolphin echolocation simulate the projection of a bottlenose dolphin's clicking sounds using computer
models. The models originate the sounds at the focus of a parabolic reflector. The parabola in the graph shows the cross
section of the reflector with focal length of 1.3 inches and aperture width of 8 inches. Write an equation to represent the cross
section of the reflector. What is the depth of the reflector? Round your answer to the nearest hundredth.

The equation __ represents the cross section.

The depth is about __ inches.
