Cleaning pumps remove oil at the rate modeled by the function r, given by r of t equals 2 plus the cosine of the quantity pi times t divided by 11 with t measure in hours and and r(t) measured in gallons per hour. how much oil will the pumping stations remove during the 6-hour period from t = 0 to t = 6? give 3 decimal places.

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
