Which angle produced the firework that travelled the highest? Which angle produced a firework that travelled the farthest horizontal distance? What are the maximum height for each angle? What are the horizontal distances? Maximum Height: Horizontal Distance: 43˚ _____________________ ______________________ 65˚ _____________________ ______________________ 35˚ ____________________ ______________________ How Many solutions are there (if any)? a.) y = x2 – 2 b.) y = x2 + 2 c.) y = 2x2 _______________________ ___________________________ _________________________ A bottlenose dolphin jumps out of the water. The path the dolphin travels can be modeled by h = -0.2d2 + 2d, where h represents the height of the dolphin and d represents horizontal distance. a. What is the maximum height the dolphin reaches? b. How far did the dolphin jump?
