Using production and geological data, the management of an oil company estimates that oil will be pumped from a producing field at a rate given by the following. 70 R(X) = - +7; OSXS 15 x + 7 R(x) is the rate of production (in barrels per day) x days after pumping begins. Find the area between the graph of R and the x-axis over the interval [5,11] and interpret the results. Desmos Area Between a Curve and the X-Axis Calculator The area is approximately square units. (Round to the nearest integer as needed.) Choose the correct interpretation of the results below. O A. It will take approximately 70 days after pumping begins to reach a thousand barrels. O B. It will take approximately 71 days after pumping begins to reach a thousand barrels. O C. Total production from the end of the first day to the end of the fifteenth day will be approximately 70 thousand barrels. O D. Total production from the end of the fifth day to the end of the eleventh day will be approximately 70 thousand barrels
