The reflector of a satellite dish is in the shape of a parabola with a diameter of 4 feet and a depth of 2 feet. to get the maximum reception we need to place the antenna at the focus. write the equation of the parabola of the cross section of the dish, placing the vertex of the parabola at the origin. convert the equation into standard form, if necessary. what is the defining feature of the equation that tells us it is a parabola? describe the graph of the parabola. find the vertex, directrix, and focus. use the endpoints of the latus rectum to find the focal width. how far above the vertex should the receiving antenna be placed?
