1) The Demon Drop at Cedar Point in Ohio takes riders to the top of a tower and drops them. A function that approximates this ride is h= - 16t^2 + 64t + 60, where h is the height in feet and t is the time in seconds. a) How many seconds does it take to reach the maximum height ? b) What is the maximum height? c) Graph/sketch the function! :

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
