Answer:

The amount of water that flows from the tank during the first 35 minutes is 4550 liters.

Step-by-step explanation:

We know that the rate is given by r(t)=200-4t and the problem asks for the net change (<em>the amount of water</em>) for the first 35 minutes.

We can use the Net change theorem:

The integral of a rate of change is the net change:

\int\limits^b_a {F'(x)} \, dx =F(b)-F(a)

Applying the above theorem we get

\int\limits^{35}_0 {200-4t} \, dt

\int _0^{35}200dt-\int _0^{35}4tdt\\\\\left[200t\right]^{35}_0-\left[\frac{t^2}{2}\right]^{35}_0\\\\7000-2450\\\\4550

The amount of water that flows from the tank during the first 35 minutes is 4550 liters.
