WINGSUIT A wingsuit flyer jumps off a tall cliff. He falls freely for a few seconds before deploying the wingsuit and slowing his descent. His height during the freefall can be modeled by the function y=-4.9x² +420, where y is the height above the ground in meters and x is the time in seconds. After deploying the wingsuit, the flyer's height is given by the function y=-3x+200. a. To the nearest whole number, how long after jumping does the flyer deploy the wingsuit? b. To the nearest whole number, what was the flyer's height when he deployed the wingsuit? WINGSUIT A wingsuit flyer jumps off a tall cliff.
