Jamie kicked a soccer ball that traveled along a path described by the parabola y = -x^2 +8x, where y equals the height of the s
2 answers:
Equation of any Parabola is of the form y=
If a is negative the parabola opens down.
The given equation of soccer ball that traveled along a path was y=
Comparing the two equations we have a=-1,b=8
As a is negative the parabola opens down and will have the maximum point at vertex .
The x of vertex is given by x=
Substituting a and b values we have:
x=
The y of vertex is y=
The highest point the soccer ball hit the ground is 16 ft.

Answer:
(A) At the intersection of the first line with the third line, the bottom left angle is 115 degrees. At the intersection of the second line with the third line, the uppercase left angle is 65 degrees.
Step-by-step explanation:
Alternate interior angles are supplementary when parallel lines are crossed by a transversal. The first description seems to be describing alternate interior angles. (See attachment)
_____
<em>Comment on orientation</em>
If the transversal is oriented horizontally, then the descriptions of the angles will be of different angles than assumed here.
