The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.03x2 + 1.53x, where x is the horizontal distance in yards and y is the corresponding height in yards.
Q1: What is the football’s maximum height? Round to the nearest tenth.
Q2: How far is the football kicked?

Best ResponseYou've already chosen the best response.0If you have a quadratic function in the form \(y=ax^2+bx+c\) the maximum is at \(x=\frac{b}{2a}\). Can you tell what your a and b are?

Best ResponseYou've already chosen the best response.0i believe a= .03 and b=1.53 . but for some reason every time i answer the question it marks it wrong

Best ResponseYou've already chosen the best response.0yes those are right, but b/(2a) isn't the height. You have to plug what you got for that into the original formula and the yvalue you get is the max height

Best ResponseYou've already chosen the best response.0so you should get \(x=\frac{1.53}{2(0.03)}=25.5\). Then plug in 25.5 for x in the original

Best ResponseYou've already chosen the best response.0For the second question, set y = 0 and solve for x. This one factors \(–0.03x^2 + 1.53x=0\)
