- Reflecting Telescope The Hale telescope at the Mount Palomar Observatory has a 200-in. mirror, as shown in the figure. The mirror is constructed in a parabolic shape that collects light from the stars and focuses it at the prime focus, that is, the focus of the parabola. The mirror is 3.79 in. deep at its center. Find the focal length of this parabolic mirror, that is, the distance from the vertex to the focus.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_forwardDesign of a satellite antenna The cross section of the satellite antenna shown is a parabola with the pickup at its focus. Find the distance d from the pickup to the centre of the dish.arrow_forward

In the illustration, how far from the vertex of the parabolic reflector should the light source be placed? All the measurements are in the feetarrow_forwardSuspension Bridge In a suspension bridge the shape of the suspension cables is parabolic. The bridge shown in the figure has towers that are 600 m apart, and the lowest point of the suspension cables is 150 m below the top of the towers. Find the equation of the parabolic part of the cables, placing the origin of the coordinate system at the vertex. [Note: This equation is used to find the length of cable needed in the construction of the bridge.]arrow_forward

For each trip between the islands, there is enough fuel for a 20-mile trip. (a) Explain why the region in which the boat can travel is bounded by an ellipse. (b) Let (0,0) represent the center of the ellipse. Find the coordinates of the center of each island. (c) The boat travels from Island 1, past Island 2 to one vertex of the ellipse, and then to Island 2 (see figure). How many miles does the boat travel? Use your answer to find the coordinates of the vertex. (d) Use the results of parts (b) and (c) to write an equation of the ellipse that bounds the region in which the boat can travel.arrow_forwardTour Boat A tour boat travels between two islands that are 12 miles apart (see figure).
