An object is thrown upward at a speed of 98 feet per second by a machine from a height of 5 feet off theground. The height h of the object after t seconds can be found using the equation h=16t2 + 98t + 5
1)When will the height be 40 feet?

2)When will the object reach the ground?

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
