Answer:
25
Step-by-step explanation:
[tex]x = \frac{ - 400 + - \sqrt{ {400}^{2} - 4 \times ( - 16) \times 6 } }{2 \times ( - 16)} [/tex]
[tex]x = - 400 + - \sqrt{160000 + 384} [/tex]
second is devided by -32
[tex]x = \frac{ - 400 + - 400}{ - 32} [/tex]
x1= 0
x2=25
So solution is 25 feet
Im not sure if that is correct
