A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y = -0.04x2+ 6.8x + 9.8, where x is the horizontal distance, in meters, from the starting point or the roof and y is the height, in meters, of the rocket above the How far horizontally from its starting point will the rocket land? ground. 0 171.43 m 342.86 m 1.43 m 171.91 m

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
