Suppose 8-in waves pass every 3 s. write an equation that models the height of a water molecule as it moves from crest to crest.

y = 4 cos

Step-by-step explanation:

Since the period is , and a period is , that makes the following equation:

=

, allowing us to display the final answer as y = 4 cos .

Yeah, almost forgot, amplitude is going to be 4 since amplitude is from the middle to each end.

Actually, I don't know anymore. It's been a long time since I did sin and cosine wave things -_-

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
