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).
Would it be 4(1)^2+2(2(1)+2)^2=100
Answer:X=-15
Step-by-step explanation:
-4x/5=12
5x-4x/5=5x12
-4x=5x12
-4x=60
-4x/-4=60/-4
x=-15
Answer:
The door was opened by whom?
Answer:
I think its choice C
Step-by-step explanation:
Because it makes more sense to me
5 * 1.5 to get 7.5, which is total pounds
7.5 - 2.8 to get how many almonds
= 4.7
Choice C makes the most sense to get that answer
i'm only in 5th grade so tell me if i'm wrong ill be ok with that
