- A man throws a ball into the air with a velocity of 96 ft/sec. Use the formula h=16t2+v0t to determine when the height of the ball will be 48 feet. Round to the nearest tenth of a second.arrow_forwardDerive the quadratic formula by using the change in variable x=y12(ba) to transform the quadratic equation x2+bax+ca=0 into one involving the difference of two squares and solve the resulting equation.arrow_forward
