The correct answer would be choice d.the material reached it's minimum temperature after 15 hours. looking at the graph, the lowest point happens after 15 hours and the temperature is at about -200 degrees.

Answer

0  represents the surface of the swimming pool.

Step by step explanation

−8, which represents the depth of water in the swimming pool

+12, which represents the height of the slide at the pool

Here 0  represents the surface of the swimming pool.

Thank you. :)
