500-gallon fish tank is being filled with water. The volume of water, in gallons per minute, is modeled by a differentiable and increasing function y for osts 10, where is measured in minutes. Select values of v) fort are given in the table below. 0 2 5 7 10 (mimtes) V() 3.5 10.0 15.5 18.5 20.0 (gallons per mitte) a. Estimate (1) Show the work that leads to your answer. Indicate units of measure. (1 point) b. Use a left Riemann sum with the four subintervals indicated by the table to approximate Lºv()dt. Using correct units, interpret the meaning of Sºv(t)dt in the context of the problem. (2 points) hope this helps :)
