The total capacity of the pool = 18000 gallon
The total volume of the pool when calculated to 2/5 = (2/5) * 18000
= 35000/5 gallons
= 7200 gallons.
Now it is given in the problem that that
Rate at which the pool is filled with water = 20 gallons per minutes
Then
20 gallons of water is filled in = 1 minute
So
7200 gallons of water will be filled in = 7200/20 minute
= 720/2 minute
= 360 minute
So 360 minute is required to fill the pool with 2/5 of the total volume of water.
2a2b3 and -4a2b3 are like terms true
When the graph is constant, you have to look for when it draws a straight line.
Look at the x axis, since it asks for the x value.
Your answer is correct! When x = 0, to x = 3, the function is constant.
