The equation for a projectile's height versus time is h(t)=-16t^2+v0t+h0. A ball is thrown vertically upward with an initial velocity of 5 ft/sec from a height of 2 ft. Which function models its motion. A. y= -16t^2-5t-2
B. y=- 16t^2+2t+5
C. y= -16t^2+5t+2
D. y= 16t^2-2t-5

Can someone me i’m confused. will give brainliest and a whole bunch of points

Find the roots of the equation below. x^2 - 6 + 9 = 0

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.
