Answer:
a)
b)
Step-by-step explanation:
It can be seen in the graph that the water velocity and solution velocity is the same, but the salt concentation will be lower
Water velocity
Solution velocity
Brine concentration =
a) Amount of salt as a funtion of time Sa(t)
b)
This value was to be expected since as the time passes the concentration will be lower due to the entrance to the pure water tank

Answer:
166 m^2
Step-by-step explanation:
The enclosing rectangle is 9m by 29m, so is 261 m^2. From that, the white space of 5m by 19m = 95 m^2 must be subtracted. The result is that the shaded area is ...
261 m^2 -95 m^2 = 166 m^2
Answer:
x-intercept: (-7.5, 0)
y-intercept: (0, 5.5)
Step-by-step explanation:
The x-intercept is where the line touches (or intersects) the x-axis, and the y-intercept is where the line hits the y-axis.
To determine the intercepts of the line, look at the graph and see where the line touches the x-axis (the axis going horizontally).
It seems to hit exactly in between -8 and -7, so the x-intercept is -7.5.
On the y-axis, the line seems to touch right between 5 and 6, so the y-intercept is 5.5.
For the x-intercept, you only need to put the x-value so it is (-7.5, 0). The y-intercept only needs the y-value so it is (0, 5.5).
