Answer D). 9 ft is correctHeight of the ball at a horizontal distance of 10 feet is 9 ft Step-by-step explanation:A ball is thrown and it follows a parabolic path. At each horizontal distance (x) the following equation models the ball’s height (y). Y(x) = Question asked is What will be height (Y) of the ball when X=10 ft Simply putting value of X in given equationwe get,Y(x) = Y(x) = Y(x) = Y(x) = Y(x) = Therefore, Height of the ball at a horizontal distance of 10 feet is 9 ft Answer D. 9 ft is...

${ \boxed{(x - 3)}}^{2} = \boxed{16}$

Step-by-step explanation:

${x}^{2} + 2x - 7 = 8x \\ \\ {x}^{2} + 2x - 8x = 7 \\ \\ {x}^{2} - 6x = 7 \\ \\ {x}^{2} - 6x + {3}^{2} = {3}^{2} + 7 \\ \\ {(x - 3)}^{2} = 9 + 7 \\ \\ { \boxed{(x - 3)}}^{2} = \boxed{16}$
