4. Suppose a gauge at the outflow of a reservoir measures the flow rate of water in units of fl/hr. The total amount of water that flows out of the reservoir is the area under the flow rate curve. Consider the flow rate function shown in the Water flow rate (f / h) 5000- figure to the right. Complete parts (a) through (d) below. a 3000- 2000 1000 8 10 Time Chr) a. Find the amount of water that flows out of the reservoir over the interval [0,4]. The amount of water that flows out of the reservoir over the interval [0,4] is (1) (Simplify your answer. Type an integer or a decimal.) b. Find the amount of water that flows out of the reservoir over the interval [8, 10]. The amount of water that flows out of the reservoir over the interval [8,10] is (2) (Simplify your answer. Type an integer or a decimal.) c. Does more water flow out of the reservoir over the interval [0,4] or [4,6]? (3) - more water flows out of the reservoir over the interval (Simplify your answers. Type integers or decimals.) d.
