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
see the attached figure
Answer:
225
Step-by-step explanation:
i used a calculater and did 90 divided by .40
The formula of a midpoint:

The formula of a distance between two points:

We have the points P(3, 5) and Q(7, 5). Substitute:

<h3>M(5, 5)</h3>

<h3>Answer:</h3><h3>Midpoint = (5, 5)</h3><h3>Distance = 4</h3>
Answer:

Step-by-step explanation:
