Given v=31 and s=0
<span>H(t) = -16t2 + vt + s
</span>
H(t) = -16t^2 + 31t
dH/dt = -32t + 31
<span>At the maximum height, dH/dt = 0
-32t + 31 =0
t = 31/32 = .96875
substitute back to H(t)
</span>
H( .96875) = 15.0 ft
ans is C

We can see that the 12 in the equation is basically the "m" in the "general slope-intercept form."
Therefore, your answer is the slope of the equation is 12.
180-145 will give you your answer cause when its a triangle they all = 180
so you add 80 + 65 = 145
so 180-145
