(rs)(4)=(2rootX)(rootX)
(rs)(4)=2x
(rs)(4)=8
(r/s)(3)=(2rootX)/(rootX)
(r/s)(3)=2
I’ll answer, but wait, do I send a picture of my work? or not? It says I have to make a table of values, so
You have the maximum height happens at 5 seconds.
Replace t with 5 and solve for h(t):
h(5) = -0.2(5)^2 + 2(5)
h(5) = -0.2(25) + 10
h(5) = -5+10
h(5) = 5
The maximum height is 5 feet.

Answer: Choice D) 56 degrees</h3>
How I got that answer:
Angle DCE is given to be 62 degrees. By the inscribed angle theorem, It doubles to 124 degrees, which is the measure of central angle DAE.
Note how angles DAF and DAE are a linear pair. This means they are adjacent supplementary angles. So they add to 180
(angle DAF)+(angle DAE) = 180
(angle DAF) + (124) = 180
angle DAF = 180-124
angle DAF = 56
Answer:
B it seems like it's the most suitable answer
