Position function: h(t) = - 4.9t² + 8.8t + 3 Ann will reach the water when h(t) = 0, so - 4.9t² + 8.8t + 3 = 0 Using the Quadratic Equation where a = - 4.9, b = 8.8 and c = 3, t { - 0.293, 2.089 } Time can't run backwards, so t = 2.089 sec. ¯¯¯¯¯¯¯¯¯¯¯¯

3 - (8 + 4x) = 2x - 23 3 - 8 - 4x = 2x - 23 - 4x - 2x = - 23 - 3 + 8 - 6x = - 18 x = - 18 / - 6 x = 3 ¯¯¯¯¯
