The path of the bird being launched in the game "Angry Birds" can be modeled by the equation h(t) == 16ť tvot+so Using the function above, you are to choose a velocity (v.) in the range of 25 ft/sec to 100 ft/sec and a starting height (s,) in the range of 2 feet to 6 feet.​

Through: (-3,-3) parallel to y= 7/3x+3

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
