Hello,

- if you decide to make one square, the length of a side will be 200/4=50. Thus the area is 50²=2500m².

- if you decide to make two squares. Let x the length of fencing used for the first square. The second square will be 200-x.

x/4 and (200-x)/4 will be the lengths of the sides of each square.

Thus their added area will be :

Note that and find the maximum of

Solve for t in , since when the ball hits the ground, its height is 0.2. 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?

Well, you can do itb.) what is the domain of h?

Find the maximumc.) How high does the ball go
