Brielle and Elaine always travel to Sunset Beach together for their summer vacation. Every year they return to the same section of beach and spend their time around the pier. Elaine notices that the water rises and falls on the posts of the pier. She thinks the height of the water can be modeled using a sinusoidal function. Brielle is snorkeling and notices that the pier posts are slimy up to the lowest level of the tide, which is feet for this particular post. Since Brielle and Elaine are always curious about the world around them on vacation, they have nothing better to do and find out there was a low point on the post at 8:00 a.M. And a high point inches higher at 2:00 p.M.

The answer is 6.25

Explained: since 2.5 has an exponent of 2, you multiply 2.5 by itself, and get 6.25

2.5 x 2.5 = 6.25

Hope This Helps
