Answer: The ball hits the ground at 5 s
Step-by-step explanation:
The question seems incomplete and there is not enough data. However, we can work with the following function to understand this problem:
(1)
Where 
models the height of the ball in meters and 
the time.
Now, let's find the time when the ball Sara kicked hits the ground (this is when 
):
(2)
Rearranging the equation:
(3)
Dividing both sides of the equation by 
:
(4)
This quadratic equation can be written in the form 
, and can be solved with the following formula:
(5)
Where:
Substituting the known values:
(6)
Solving we have the following result:
This means the ball hit the ground 5 seconds after it was kicked by Sara.
<span>1. You are given an angle.
2. Draw a ray with one endpoint. This endpoint will be the vertex of the new angle.
3. Place the compass on the vertex of the given angle and swing an arc that intersects both rays of the given angle.
4. Place the compass on the vertex of the new angle and swing an arc similar to the first one you created.
5. Open the compass to the width of the intersection points of the rays and arc of the given angle.
6. Place the compass on the intersection point of the ray and arc of the new angle and swing another arc that intersects the first.
7. Draw a ray through the new vertex and the intersection point of the two rays.
8. This second ray creates an angle that is congruent to the given one.</span>
