Answer:
(a)100 liters
(b)400 liters
(c)300 liters
(d)No, because the line does not pass through (0,0).
Step-by-step explanation:
(a)From the graph
When the time (in hours) = 0
The volume of water in the pond = 100 liters
Therefore, at 0 hours, there were 100 liters of water in the pond.
(b)From the graph
When the time (in hours) = 1
The volume of water in the pond = 400 liters
Therefore, at 1 hour, there were 400 liters of water in the pond.
(c)To find the rate at which the water increases, we use our result from parts (a) and (b).
At 0 hour, the volume of water in the pond= 100 liters
At 1 hour, the volume of water in the pond = 400 liters
Change in the volume after 1 hour = 400 - 100 =300 liters
The water increases by 300 liters for each hour that water is added.
(d)We see that the results in parts (b) and (c) are not the same.
This is because the line does not pass through (0,0).
