So you have a question or Assignment?

anonymous · Answer

i dont understand how to do the project 
i just want help explaining how to do it that is it

anonymous · Answer

what kind of a project?

anonymous · Answer

a football player kicked a 40-yard punt. The path of the ball was modeled by y = -0.0375x^2 + 1.5x, where x and y are measured in yards. What was the maximum height of the ball? The player kicked the football toward midfield from the 18 yard line. Over which yard line was the ball when it was its maximum height?

anonymous · Answer

and you have to draw a picture of the problem then use vertex formula to write the equation in graphing form then graph it then find the x-intercept and the y-intercepts of the graph

anonymous · Answer

max height is at the vertex

anonymous · Answer

yes but how do i get that?

anonymous · Answer

here is a picture http://www.wolframalpha.com/input/?i=-0.0375x^2+%2B+1.5x%2C+domain+0..40

anonymous · Answer

ok thanks @satellite73

anonymous · Answer

first coordinate of the vertex is $-\frac{b}{2a}$ which in your case it $-\frac{1.5}{2\times .0375}=20$

anonymous · Answer

if you replace $x$ by $20$ you get $y=15$ so the max height is 15 feet up

anonymous · Answer

ok thanks
