23. A 20-in. satellite dish for a television has parabolic cross sections. A coordinate system is chosen so that the vertex of a cross section through the center of the dish is located at (0, 0). The equation of the parabola is modeled by x² = 25.2y, where x and y are measured in inches. -10 10 a. Where should the receiver be placed to maximize signal strength? That is, where is the focus? (See Example 1) b. Determine the equation of the directrix.
