Jada is riding on a Ferris wheel. Her vertical position, in feet, is modeled by the function \(h(m) = 100\sin\left(\text-\frac{\pi}{2} + \frac{2\pi m}{10}\right) + 110\), where \(m\) is the number of minutes since she got on the ride.
The vertical position, in feet, of a point, \(P\), on a windmill is represented by \(y = 5\sin\left(\frac{2\pi t}{3}\right)+20\), where \(t\) is the number of seconds after the windmill started turning at a constant speed. Select all the true statements.
The windmill blades are 5 feet long.
The windmill blades make 5 revolutions per second.
The midline for the graph of the equation is 20.
The windmill makes one revolution every 3 seconds.
The windmill makes 3 revolutions per second.

A carousel has a radius of 20 feet. The carousel makes 8 complete revolutions.
A \(\frac{\pi}{2}\)-radian rotation takes a point, \(D\), on the unit circle to a point, \(E\). Which other radian rotation also takes point \(D\) to point \(E\)?
\(\frac{3\pi}{2}\)

A windmill blade spins in a counterclockwise direction, making one full revolution every 5 seconds.
Which statements are true? Select all that apply.
After 15 seconds, the point \(W\) will be in its starting position.
After \(\frac{1}{5}\) of a second, the point \(W\) will be in its starting position.
In 1 second, the point \(W\) travels through an angle of \(\frac{\pi}{5}\).
The position of \(W\) repeats every 5 seconds.
The position of \(W\) repeats every 10 seconds.
Here is the graph of a trigonometric function.
Which equation has this graph?
\(y = \text-2\sin(2x)\)
\(y = 2\sin\left( 2\pi \left(x+\frac{1}{4}\right)\right)\)
\(y = 2\sin\left( 2\pi \left(x-\frac{1}{4}\right)\right)\)
\(y = 2\sin\left( 2\pi \left(x-\frac{\pi}{4}\right)\right)\)
