Question

subject: sine graphs and cosine graphsThe table and graph below record the data for the depth of the tide.  Use the information to identify the midline of the graph.options:a. y = 1.6b. y = 0c. y = 5.4d. y = 3.6

Answer 1

the midline of the graph is the horizontal line that divides the graph in half.

to find it we can take the maximum value and the minimum and substract them together to find the total distance and divide it by 2 to find the halfpoint

the maximum value is 5.2 and the minimum is 2.02

`(5.2-2.02)/(2)=1.59`

the halfpoint will be at a 1.59 unit from the maximum value and the minimum value

`\begin{gathered} 5.2-1.59=3.61 \\ 2.02+1.59=3.61 \end{gathered}`

the midline of the graph will be at y=3.6
