Your question is incomplete, here is the complete question;
A football is kicked into the air and follows the path defined by h=-2x^2+16x, where x is the time in seconds and h is the height in meters. What is the maximum height reached by the football?
Answer:
maximum height=h=32 meters
Step-by-step explanation:
The given equation is the equation of the parabola or quadratic equation.
The maximum height of the ball will occur at the axis of symmetry.
For the axis of symmetry let h=0,
so,

comparing this equation to standard quadratic/parabola's equation, we get
a= -2, b=16 and c=0
Formula for axis of symmetry is x=-b/2a
x=-16/2*(-2)
x=-16/-4
x=4 it means axis of symmetry is vertical line through the point x=+4, so the maximum height will occur at x=+4
put x=4 to get maximum height as;


Maximum height
Answer:
The quotient is x² + 6x +3
Remainder = -1
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Polynomial equation
f(x) = x³+5x²−9x−7
By using synthetic division
<em> x = 2 </em> 1 5 -9 -7
<u> 0 1 12 6</u>
<u> 1 6 3 </u><em><u> -1 </u></em><u> </u>
The quotient is x² + 6x +3
Remainder = -1

Check step-by-step.
Step-by-step explanation:
Okay, so. She gets 5 dollars and she does 15 chores. You would multiply it.
5 * 15 = $75
Then you would subtract 112 and 75.
112 - 75 = 37.
She will get $75. Then, she will need to gather $37
