A windmill blade spins in a counterclockwise direction, making one full revolution every 5 seconds.

Which statements are true? Select all that apply.

In 1 second, the point W  travels through an angle of \frac{1}{5}.

After \frac{1}{5} of a second, the point W  will be in its starting position.

After 15 seconds, the point W  will be in its starting position.

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=2sin(2\pi(x+\frac{1}{4}))

y=2sin(2\pi(x-\frac{1}{4}))

y=2sin(2\pi(x+\frac{\pi}{4}))

y=-2sin(2x)
