Mason throws a ball straight up into the air with an initial velocity of 12m/s2 12 m / s 2 . If the point at which Mason released the ball from his hand was 1.25 meters above the ground is modeled by the equation h(t) = −4.9t2+12t+1.25 h ( t ) = - 4 . 9 t 2 + 12 t + 1 . 25 , how long will the ball be in the air for rounded to the nearest tenth?

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.
