Answer:

a. Taking the height of the water's surface as 0, we have

-16t^2 + 6t + 12 = 0 divide through by -2

8t^2 - 3t - 6 = 0 this will not factor.....using the quadratic formula, we get that t = about 1.07 seconds

b. The max height above the pool is given by c - [ b^2 ] / [4a] = 12 - [36]/ [ 4(-16)] =

12 + 36/64 =

12 + 9/16 ft = 12.5625 ft
