Question

A radio transmitter sends a radio wave from the top of a 50-foot tower. The wave is represented by the graph shown at the right. What is the equation of this radio wave?

• A. y = 1.5 sin x
• B. y = sin 1.5x
• C. y = cos 1.5x
• D. y = 1.5 cos x

Answer 1

The correct option is A y = 1.5 sin x

This graph is of sin x where its amplitude is 1.5.
