Xavier is riding on a Ferris wheel at the local fair. His height can be modeled by the equation H(t) = 20cosine of the quantity 1 over 15 times t + 30, where H represents the height of the person above the ground in feet at t seconds. Part 1: How far above the ground is Xavier before the ride begins? Part 2: How long does the Ferris wheel take to make one complete revolution? Part 3: Assuming Xavier begins the ride at the top, how far from the ground is the edge of the Ferris wheel, when Xavier's height above the ground reaches a minimum?

-.- I just needed help figuring it out I have been stuck on it for hours and I thought openstudy would help but obviously not @IrishBoy123

Okay for part 1 i think you just have to substitute in 0 for t. H(0)= 20cos(pi/15(o))+30 which is 50. But I'm not sure if that's right.

why not just draw the equation? i can guess sorta what you are trying to do, but that really defeats the point. loads of people here want to help and learn.
