The formula for the area of a trapezoid is A=\frac{1}{2}h(b_1+b_2),A= 21 h(b 1 +b 2 ), where hh is the height and b_1b 1 and b_2b 2 are the two bases. Rewrite the formula to solve for hh in terms of A, A, b_1b 1 and b_2.b 2

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m
