Answer:
A vertex on polygon ABCD and its corresponding vertex on polygon AGHBGHCGHDGH are always equidistant from the line of reflection. Each of the four line segments (, for example) is perpendicular to and cut in half by the line of reflection, . This means that is a perpendicular bisector of those line segments.

Approximately, how long does it take until the soccer ball hits the ground again?
0.6 sec
0.8 sec
1.6 secs
2.8 secs
Answer:
Maximum height=9.8 ft and Time taken by soccer ball will be 0.8 secs
Step-by-step explanation:
Since, the ball kicked will take the motion of projectile, therefore using the equation: h(t)= , where h(t) is the height of the soccer ball, a is the acceleration whose value is -16 ft/sec^2 and v= 35 feet and d is the starting height which is equal to zero.
Therefore, h(t)= (1)
Differentiating this equation with respect to t,
=
=
=
Substituting the value of t in equation (1),
=
=
≈9.8ft
Hence, option C is correct.
Now, In order to determine the time taken until the soccer ball hits the ground, we take the equation:
Since, when the ball hits the ground, the height will become equal to zero, therefore we have, h(t)=0
Now,
Then, one solution is t=0 and the other is:
≈
Hence, option B is correct.
Answer:
9.8 ft for the maximum height
1.6 sec for the time it’ll take for the ball to hit the ground again
I just took a test and it shows me what I got wrong alongside the correct answers. And this was a question it asked.
