Answer:

Step-by-step explanation:
We have been given that a polynomial function
models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.
In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:

The zeroes of this polynomial occur when either
or
.
The equation
have no real solutions. Therefore, the only time when the roller coaster is at the ground is at 
Answer:
Please include the image of your triangle for a better answer. Without all the information it is not possible to explain or identify the correct solution.
Step-by-step explanation:
You can relate the relationship of the legs of a triangle using the Pythagorean theorem,
where c is the hypotenuse.
