1. Suppose you have to use exactly 200 m of fencing to make either one square enclosure or two seperate square enclosures of any sizes you wish. What plan gives you the least area? The greatest area?

2. If a ball is thrown upward from a building 30m tall and the ball has a vertical velocity of 25m/s, then its approximate height above the groundtseconds later is fiven byh(t)=30=25t-5t^2

a.) after how many seconds does the ball hit the ground?

b.) what is the domain of h?

c.) How high does the ball go

Thank you !!!!!!
