Throughout the day, the depth of water at the end of a dock varies with the tides. The function h(t)=5cos(0.5t-2)+7 represents t

dybincka [34]

Remember that for a graphic of a trigonometric functions of the form $f(x)=Acos(Bx+C)+D$
$A$ is the amplitude of the function
$f(x)=D$ is the midline of the trigonometric function

We know form our problem that $A=5$ , so the amplitude of our function is 5. We also know that the $D=7$ . So the midline of our function is the line $h(t)=7$ .

Using those two features we can conclude that the graph <span>that shows the height of the water at the dock at any time after midnight is: </span>
