The figure given alongside shows the path of a diver. When she takes a jump from the diving board . Clearly it is parabola .
Annie was standing on a diving board, `48` feet above the water level . She took a dive into the pool. Her height (in feet ) above the water level at any time 't' in seconds is given by the polynomial h (t) such that
`h(t)=-16t^(2)+8t+k`
The zeroes of the polynomial `r(t)=-12t^(2)+(k-3)t+48` are negative of each other. Then k is :
