Answer:
0.319 m³/s
Step-by-step explanation:
Data provided:
Initial volume in the river = 255 m³
Final volume required in the storage = 325 m³
Average outflow = 0.30 m³/s
Duration for raising the level = 1 hour = 3600 seconds
Now,
The actual volume required to raise the volume to 325 m³
= Final volume - Initial volume
= 325 m³ - 255 m³
= 70 m³
also,
the amount of outflow in 1 hour = Average rate of outflow × Time
= 0.30 m³/s × 3600 s
= 1080 m³
Therefore,
the total volume required = 1080 m³ + 70 m³ = 1150 m³
Now,
the average rate of inflow required =
=
= 0.319 m³/s
Answer:
The relationship between two variables is decreasing and linear.
Step-by-step explanation:
From the given table it is notice that the function passing through the points (1,5), (2,-1), (3,-7) and (4,-13).
Slope of the function between first two points (1,5) and (2,-1) is
Slope of the function between last two points (3,-7) and (4,-13) is
The rate of change or slope of the function is constant.
From the given table it is noticed that the values of y decreased by 6 units as the values of x increased by 1 units.
Since the rate of change constant and negative, therefore the relationship between two variables is decreasing and linear.
