Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 4.35 ft at midnight, rises to a high of 8.3 ft, falls to a low of 0.4 ft, and then rises to 4.35 ft by the next midnight.

What is the equation for the sine function f(x), where x represents time in hours since the beginning of the 24-hour period, that models the situation?

Enter your answer in the box.

My answer: 3.95sin(pix/12)+4.35

This has been answered before:

Amplitude Max 8.3 ft min 0.4 means amplitude = 7.9/2 = 3.95 check

Shited up to midline 4.35 check

Period = 24 2pi/24 = 1/12 pi check

sine wave

Looks good to me
