Answer:
110.9 feet
Step-by-step explanation:
The function that models the flight of the ball is
where f(x) is the vertical distance in feet and x is the horizontal distance the ball travels
If the ball hits the ground, then f(x)=0
![\implies - 0.02 {x}^{2} + 2.2x + 2 = 0](https://tex.z-dn.net/?f=%20%5Cimplies%20%20-%200.02%20%7Bx%7D%5E%7B2%7D%20%20%2B%202.2x%20%2B%202%20%3D%200)
The solution is given by the quadratic formula:
![x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%20b%20%5Cpm%20%5Csqrt%7B%20%7Bb%7D%5E%7B2%7D%20%20-%204ac%7D%20%7D%7B2a%7D%20)
We substitute a=-0.02, b=2.2, and c=2 to get:
![x = \frac{ - 2.2 \pm \sqrt{ {2.2}^{2} - 4 \times - 0.02 \times 2} }{2 \times - 0.02}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%202.2%20%5Cpm%20%5Csqrt%7B%20%7B2.2%7D%5E%7B2%7D%20%20-%204%20%5Ctimes%20%20-%200.02%20%5Ctimes%202%7D%20%7D%7B2%20%5Ctimes%20%20-%200.02%7D%20)
This implies that:
![x = 110.90 \: or \: x = - 0.90](https://tex.z-dn.net/?f=x%20%3D%20110.90%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%200.90)
Since we are dealing with time,
![x = 110.90](https://tex.z-dn.net/?f=x%20%3D%20110.90)
To one decimal place, we have 110.9 feet
Pretty sure it’s C sorry if wrong
