What function best represents a sine function with an amplitude of 4, a period of pi over 6, and a midline at y = −2?

Let us suppose the sine function is in the form

We have been given that the amplitude is 4. It means we have

Now, period is given by

Thus, we have

Now, we have been given that the mid line is. Hence, we have

Therefore, the sine function is given by

25% is the answer

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
