3. After a rainstorm, runoff water flows into a reservoir at a rate that is 1 000 000 well-approximated by w(t) = 0.01/2 + 2000 L/minute. There is initially 1 million L of water in the reservoir. a) Use software (or your own brain) to draw a graph of this function, to see why this provides us with a realistic model. b) Find the total amount of water in the reservoir (assuming that no water flows out) after six hours have passed.A A 100 000000 360 X + arctan + 1 000 000 Reverse Contrast V 200 000 V 200000 5- Braille Mode = 1 151 554. 621 75 Grid Axis Numbers Minor Gridlines Arrows X-Axis add a label -10
