The cross section of television antenna dish is a parabola and the receiver is located at the focus, 5 feet above the vertex. This problem first came to me in high school, and a couple times since, and I even assigned it for extra credit in one of my calculus classes after I became a teacher. So I know the solution. At its closest point, the main cable which forms the parabola is 5 m above the road. The rooms total length is 35 feet 10 inches The conic section that is being used has to be a parabola, circle, ellipse, or hyperbola. The graph has a vertex at 12,0 c. The graph has a focus at 13,0 d the center of the graph is at 0,1. The graph is a parabola with its vertex at -2,3 b. The graph is a hyperbola that passes The graph is an ellipse centered at 0,0 b.

The graph is a hyperbola that passes through 0,0 and 2,1 c. Ask a question for free Get a free answer to a quick problem.
