Beginning from a depth of 35 feet below the surface, a whale swims upward and jumps to a height of nearly 17 feet above the surface. Nodel with Math Use an inequality to model the possible change in the number of feet, \( r \), of the whale's elevation.

To model the possible change in the whale's elevation, let's define \( r \) as the whale's elevation relative to the surface of the water: - **Initial Position:** The whale starts **35 feet below** the surface, so its initial elevation is \( -35 \) feet. - **Final Position:** The whale can jump **up to nearly 17 feet above** the surface, so its maximum elevation is \( +17 \) feet. Using an inequality to represent the range of possible elevations \( r \): \[ -35 \leq r \leq 17 \] **Explanation:** - The inequality \( -35 \leq r \) ensures that the whale does not go below 35 feet below the surface. - The inequality \( r \leq 17 \) ensures that the whale does not exceed 17 feet above the surface. **Graphical Representation:** ``` Elevation (r) | * | | | | |---------------------|--------------------- -35 0 17 ``` The asterisk (*) represents the range of possible elevations the whale can achieve, from 35 feet below to 17 feet above the surface. **Final Inequality:** \[ -35 \leq r \leq 17 \]
