Answer:
V'(t) =
If we know the time, we can plug in the value for "t" in the above derivative and find how much water drained for the given point of t.
Step-by-step explanation:
Given:
V = , where 0≤t≤40.
Here we have to find the derivative with respect to "t"
We have to use the chain rule to find the derivative.
V'(t) =
V'(t) =
When we simplify the above, we get
V'(t) =
If we know the time, we can plug in the value for "t" and find how much water drained for the given point of t.
Since the lines are parallel and you know the slope of 
is -2, you know the slope of line 
will also be -2. You can see on the coordinate grid that line crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get = -2x - 1.
