yes well kinda im pretty sure
Step-by-step explanation:
Answer:
hmmmmm
Step-by-step explanation:
yh about that, id just give up
Check the pictures below.
if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.
if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is
h(s) = -4.9(s - 2)(s + 1).
I think its 12.
I could be wrong. Let me know.
