A satellite dish measures 64 feet across its opening and 16 feet deep at its center. The receiver should be placed at the focus of the parabolic dish. Where is the focus? The focus will be at (0, 32) so the receiver should be placed 64 feet from the vertex. The focus will be at (0, 32) so the receiver should be placed 16 feet from the vertex (C) The focus will be at (0, 16) so the receiver should be placed 32 feet from the vertex
