Question 114977
let the bottom of the bowl be the origin (0,0)


a cross-section through the center of the bowl gives a parabola with the vertex at the origin, passing through (5,3) and (-5,3)


h and k are zero ___ x^2=4py ___ 5^2=4p(3) ___ 25=12p ___ 25/12=p


the focus (where the receiver should be placed) is 25/12 ft (or 25 inches) above the origin
