1. The problem statement, all variables and given/known data A parabolic communications antenna has a focus 6 feet above its vertex. Write an equation for the parabola and find the width of the antenna 9 feet from the vertex. Locate the origin strategically. 2. Relevant equations y= x^2 (parent equation for parabola) 3. The attempt at a solution focus = 4p. standard form of parabola , (x-h)^2 = 4p(y-k)^2 4 * 6 = 24 so (x-h)^2 = 24(y-k)^2. It doesn't give you the origin how are you supposed to write the formula?
