PLEASE HELP MAX POINTSThe shape of this particular section of the rollercoaster is a half of a circle. Center the circle at the origin and assume the highest point on this leg of the roller coaster is 30 feet above the ground. Write the equation that models the height of the roller coaster.Start by writing the equation of the circle. (Recall that the general form of a circle with the center at the origin is x2 + y2 = r2.

The first few steps in solving the quadratic equation 5x2 + 27x = 14 − 13x by completing the square are shown. 5x2 + 27x = 14 − 13x 5x2 + 40x = 14 5(x2 + 8x) = 14 Which is the best step to do next to solve the equation by completing the square: 5(x2 + 8x + 16) = 305(x2 + 8x + 16) = 945(x2 + 8x + 4) = 185(x2 + 8x + 4) = 34
