Iver 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

enot [183]

Answer:

$f(x)=3.95sin(\frac{\pi}{12}x)+4.35$

Step-by-step explanation:

Recall:

Sinusoidal Function -> $f(x)=a*sin(bx+c)+d$
Amplitude -> $a$

Period -> $\frac{2\pi}{|b|}$
Phase Shift -> $-\frac{c}{b}$

Vertical Shift/Midline -> $d$

Given:

Amplitude -> $a=8.3-4.35=3.95$
Period -> $\frac{2\pi}{|b|}=\frac{2\pi}{|24|}=\frac{2\pi}{24}=\frac{\pi}{12}$
Phase Shift -> $-\frac{c}{b}=-\frac{0}{24}=0$
Vertical Shift/Midline -> $d=\frac{8.3+0.4}{2}=\frac{8.7}{2}=4.35$

Conclusion:

The equation that models the situation is $f(x)=3.95sin(\frac{\pi}{12}x)+4.35$

Hope this helped! I've attached a graph of the function so you can understand it better!
