Hyperbola--Matching curve to nuclear cooling towers.

Nuclear cooling towers are constructed in the shape of a hyperboloid. For this activity, you are given two points, C and D, that are the foci of the hyperbola, and a point E on the hyperbola. Try to match the hyperbola to the curve of the nuclear cooling tower shape.
