Choose all of the equations that represent a parabola with the focus (0,4) and the vertex (0, -6). A. x2 = 20 (y + 1)
B. x2 = 40 (y + 6)
O c. 20y = x2 - 20
D. 40y = (x + 6)2
E. 40y = x2 - 240

The standard form of the equation of a circumference is given by the following expression:

 (x-h)2 + (y-k)2 + r2
