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.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

the answer is 13/48
