9. The path of a diver diving off a 10- foot platform can be represented by
the function h(x) = -0.5(x2 - 4x - 21).
where h is the diver's height above
water and x is the horizontal distance
from the platform (in feet).
Find the zeros of the function.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

The suare root of 9x plus 7 plus the square rot of 2x equall to 7
