Algebra 2 Help
« on: February 17, 2016, 06:30:45 pm »
I'm stuck on a problem ... any help would be appreciated.

---

A stunt motorcyclist makes a jump from one ramp 20 feet off the ground to another ramp 20 feet off the ground. The jump between the ramps can be modeled by y = -1/640x^2 + 1/4x + 20 where x is the horizontal distance (in feet) and y is the height above the ground (in feet).

*insert diagram*

a. What is the motorcycle's height r when it lands on the ramp? (I've got this one -- it's stated above to be 20 ft.)
b. What is the distance d between the ramps?
c. What is the horizontal distance h the motorcycle has traveled when it reaches its maximum height?
d. What is the motorcycle's maximum height k above the ground?

I also need to get this done really soon ... like, in two hours.

EDIT: I think I got it ... finally ...

its way easier if you have a graphing program, though it seems like you already got it
