Find all the real zeros of f(x) = x - 5x + 5x + 3, given f(3) = 0. Enter the zeros from lowest to highest, separated by commas and no spaces. Enter exact value, not decimal approximations. For square root use "sqrt" (e.g. sqrt(3)) 3 = A = 896 A rocket is fired upward from some initial distance above the ground. Its height h, (in feet) above the ground t seconds after it is fired is given by: h(t) = -16t + 192t + 720 What is the rocket's maximum height? A How long does it take for the rocket to reach its maximum height? A/ feet. A seconds. After it is fired, the rocket reaches the ground at t = seconds.
