The answer is C. 5
This is the answer because
125 / 2 = 62.5
125 / 3 = 41.6_
125 / 5 = 25
125 / 7 = 17.86
As you can see 5 is the only number it can be divisible by.
Hope that helps!!
P(perfect square) is even
H = -16t² + 64t + 80 (:16)
H = -t² + 4t + 5
/\ = b²-4ac
/\ = 4²-4.(-1).5
/\ = 16+20
/\ = 36
Yv = -/\ / 4a
Yv = -36/4.(-1)
Yv = -36/-4
Yv = 9
A. 16^{5}
C. 4^{5}
i don't know b. tho
