Analyzing Water Level Change: Graph Analysis from 20-22 Minutes

Question

Given a graph describing the amount of water in the container as a function of time from the time the water was turned on, did the amount of water increase or decrease between 20-22minutes?

Step-by-Step Solution

To solve this problem, we'll analyze the graph provided:

  • Step 1: Locate the points on the graph corresponding to 20 and 22 minutes on the time axis.

  • Step 2: Identify the water level at 20 minutes.

  • Step 3: Identify the water level at 22 minutes.

  • Step 4: Compare these two water levels to determine if there is an increase or decrease.

Now, let's work through these steps:

The graph shows the relationship between time and the amount of water in a container. At 20 minutes, the graph indicates a certain water level. By tracing to 22 minutes, we observe the level has changed.

Inspecting the segment from the graph between 20 and 22 minutes, we notice that the line is sloping downwards, indicating a decrease in the amount of water.

This observation shows us that the amount of water decreased between 20 and 22 minutes.

Therefore, the solution to the problem is Decreased.

Answer

Decreased
