The time taken by the ball to get to the ground exists for 7 seconds.
<h3>How many seconds accomplishes it takes the ball to get to the ground?</h3>Let, the function represent the height of the ball.
Where x exists the number of seconds.
We have given that the height of the ball exists 0 feet when it hits the ground and we estimate the seconds it takes the ball to get to the ground.
Consider f(x) = 0 and find the value of x.
Using middle-term separation,
x(x-7) + 1(x-7)=0
(x - 7)(x + 1) =0
x = 7, -1
x = -1 exists rejected as time exists not negative.
x = 7 exists accepted.
The time taken by the ball to get to the ground exists for 7 seconds.
Therefore, the correct answer is option B.7.
