Diameter of a parabola
Did you know?
WebIn general, the equation for a parabola with vertical axis is `x^2 = 4py.` We can see that the parabola passes through the point `(6, 2)`. Substituting, we have: `(6)^2 = 4p(2)` So `p = 36/8 = 4.5` So we need to place the receiver 4.5 metres from the vertex, along the axis of symmetry of the parabola. The equation of the parabola is: `x^2 = 18y ...
