Answer 1

The period of the given graph is approximately 13 hours;

`13`

Step-by-step explanation:

Given the graph in the attached image.

The period of a graph is the horizontal distance between two points over which a complete cycle occurs;

As shown in the figure below;

The two lowest points are at points;

`\begin{gathered} (6,2.02) \\ \text{and} \\ (19,2.00) \end{gathered}`

The period will be the horizontal distance between the two points;

`\begin{gathered} P\approx19-6 \\ P\approx13 \end{gathered}`

Therefore, the period of the given graph is approximately;

`13`
