is the functions that determines the height of the ball in Feet, after x seconds being thrown.
so for example to calculate how many feet above the ground in the ball 5 seconds after being thrown, we calculate f(5)
feet
to solve our problem we need to find x such that f(x)=0
so we solve :
using the quadratic formula, le a=1, b=-7, c=-8
so
, which cannot be the solution to our problem.

Answer:
B
Step-by-step explanation:
Substitute the values in for x and y and you will see B is correct.
This transformation is called a rotation:-D
The answer is 110 degrees because a right angle is 90 and thats obtuse so its more than 90 and 110 is the only one more than 90
