Asked by kat
At the amusement park, you decide to ride the Ferris wheel, which has a maximum height of 80 meters and a diameter of 40 meters. It takes the wheel seven minutes to make one revolution. Write the sinusoidal function, f(t), that models the height of your chair at any time, t.
I got f(t)=20sin(2pi/7)t+40. Is this correct?
I got f(t)=20sin(2pi/7)t+40. Is this correct?

Your 2pi/7 t is correct.
To get the max height of 80 with a radius of 20, you need
20sin(2pi/7t)+60
It could also be a cosine function, or either sine or cosine with a phase shift. Your pure sine function indicates that at t=0, the chair is level with the axle of the wheel.
