Question 1152589: The function h(t)=25-10cos(pi/3x) gives the height above the ground, in feet, of a passenger on a ferris wheel x minutes after the ride begins. During one revolution of the ferris wheel, for how many minutes is the passenger at least 25 feet above the ground?
Thank you for any help!

You can put this solution on YOUR website! The function h(t)=25-10cos(pi/3x) gives the height above the ground, in feet, of a passenger on a ferris wheel x minutes after the ride begins. During one revolution of the ferris wheel, for how many minutes is the passenger at least 25 feet above the ground?
-------------
You should clarify:
cos((pi/3)x) ?
Or cos(pi/(3x)) ?
================
Also, it's h(x)
h(x)=25-10cos(x*pi/3)
=============================
25 is the mid-line of the sinusoid, so it's 1/2 of the cycle.
Once cycle is 2pi*(3/pi) = 6 minutes
1/2 that is 3 minutes.
