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
