For a physics experiment, students toss a basketball in the air from the top of a school building. they write the expression y=-16x^2+48x+56 to represent the hight, in feet, of the basketball after x seconds. based on the expression, what is the hight, in feet, of the school building?

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

Find the cosine function that is represented in the graph.
