Aball is kicked into the air and follows the path described by
h(t)= – 4.9t^2 + 6t + 0.6, where t is the time in seconds and h is the
height in meters above the ground. find the maximum height of the
ball. what value would you have to change in the equation if the
maximum height of the ball is more than 2.4 meters?

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.
