Find the focal length of this parabolic mirror, that is, the distance from the vertex to the focus.arrow_forwardAPPLICATIONS Parabolic Reflector A lamp with a parabolic reflector is shown in the figure. The bulb is placed at the focus, and the focal diameter is 12 cm. aFind an equation of the parabola. bFind the diameter d(C,D) of the opening, 20 cm from the vertex.arrow_forwardSatellite Dish A reflector for a satellite dish is parabolic in cross section, with the receiver at the focus F. The reflector is 1 ft deep and 20 ft wide from rim to rim (see the figure). How far is the receiver from the vertex of the parabolic reflector?arrow_forward
