Calculator Review #2 Because of rainfall from 9am on a given day, water enters an open reservoir at the rate of where R(t) is measured in gallons per hour and t is measured in hours after 9am (so 0 <= t <= 12). To prevent overflow, water is pumped out of the reservoir at the constant rate of k gallons per hour. The reservoir holds 500,000 gallons of water both at 9am and 9pm. A. What is k? Round your answer to the nearest whole number.
