Answer:
Step-by-step explanation:
14x + 7y is the correct answer
Answer:
b^20/a^12
Step-by-step explanation:
b to the power of 20 over a to the power of 12
3-5w+12+2w-3
(3+12-3)=12
(-5w+2w)=-3w
-3w+12
We have that
<span>y = -x</span>²<span>+8x
we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0
the solution is
x=0
x=8
the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft
the answer is
8 ft
