Answer: y = (1/4)x - 1
Step-by-step explanation:
Slope intercept form is . The
-intercept is -1 so we have
. To find
, look at the points
and
. The line goes up 1 and over 4, so the slope,
, equals
. Thus the full equation is
.

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.
