Harper kicked a beach ball to her sister in the pool. The height of the ball in feet, h(x), can be represented by h(x)= -0.5x^+4x, where x is the horizontal distance the traveled in feet. If the height of the ball is now 3.5 feet, write and solve an equation to determine which represents x, the horizontal distance the ball has traveled. A. x= 1 foot B. x= 7 feet? C. Both A and B D. Neither A OR B.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

∠cbe and ∠deb are same-side interior angles.

i took the test

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
