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:
11.6 miles
Step-by-step explanation:
Given that:
Distance from J2 to J3 = 8.7 miles
Distance between J1 and J2 = 1/3 of J2 toJ3
Hence, distance between J1 and J2 becomes :
1/3 * 8.7 miles = 2.9 miles
Distance from J1 to J3 equals :
(J1 to J2) + (J2 to J3)
2.9 miles + 8.7 miles
= 11.6 miles
- <u>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</u>
- <u>Convert the problem to an equation using the percentage formula: P% * X = Y.</u>
- <u>P is 10%, X is 150, so the equation is 10% * 150 = Y.</u>
- <u>Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.</u>
- <u>Multiply by 100 and add a percentage </u><u>sign</u>
- <u>0.876 = 0.876 * 100 = 87.6%</u>

To find the distance between the points given in the figure of the problem above, you must apply the formula for calculate the distace between two points, which is shown below:
d=√[(x2-x1)^2+(y2-y1)^2]
When you substitute the values, you obtain:
d=√[(x2-x1)^2+(y2-y1)^2]
d=√[(-1-2)^2+(-5-5)^2]
d=10.4
The answer is:10.4
Answer:
they form a 90 degree angle
Step-by-step explanation:
perpendicular (⊥) always implies 90 degree angles
parallel (║) always implies they never intersect
