Ineed proper and an easy to understand explanation. a football is kicked at 40 yards away from a goal post that is 10 feet high. its path is modeled by y = -0.03x^2 + 1.6x, where x is the horizontal distance in yards traveled by the football and y is the corresponding height above the ground in feet. does the football go over the goal post? how far above or below the goal post is the football? use two or more complete sentences to explain your answers. (hint: the unit conversion is built into the given function.)

So since we know that the post is 40 yards away, plug in 40 into the x variable of the equation to solve. If y is greater than 10 when x = 40, then it made it over. If y is less than 10 when x = 40, then it does not make it over.

Firstly, solve the exponent:

Next, solve the multiplications:

Lastly, solve the addition and your answer will be:

Since the football was 16 ft high, as opposed to the goal post's 10 ft, when it was at the goal post, it had successfully gone over the post. And since 16 ft is 6 ft higher than 10 ft, the football was 6 ft higher than the goal post when it went over.

answer:   y=2x-3
