LaToya throws a ball from the top of a bridge. Her throw is modeled by the equation y = -0.6x^2 + 3x + 8, and the bridge is modeled by the equation y= -0.2x +5. About feet (round to two decimal places as needed)

Lindsay is creating a bridge out of dried pasta and glue. in her plans, she sketches the graph to determine the lengths of the noodles, in centimeters, needed for the arch to increase the length of the bridge in 1 centimeter increments.which function did lindsay use to create her design? f(x) = (x – 5)2 + 8 f(x) = –(x + 5)2 + 8 f(x) = 0.5(x + 5)2 + 8 f(x) = –0.5(x – 5)2 + 8
