I think it is x becase you said (there were x fans)
H(t) = -16t^2 +704t = -16(t^2 -44t)
Putting in vertex form: -16(t^2 -44t +484) + 704
h(t) = -16(t-22)^2 + 704
It takes 22 seconds to reach the maximum height, which is the vertex of the parabola at (22,704)
A)
D+Y=50
D=Y+10
b)
Y+10+Y=50
2Y+10=50
2Y=40
Y=20
Therefore there are 20 in yearbook and 30 in drama.
To check our work:
D=Y+10
30=20+10
30=30 [CHECKS TRUE]
Answer:
h = 7
