A valve on a storage tank is opened for 4 hours to release a chemical in a manufacturing
Chapter 5, Problem 142(choose chapter or problem)
Modeling Data A valve on a storage tank is opened for 4 hours to release a chemical in a manufacturing process. The flow rate R (in liters per hour) at time t (in hours) is given in the table.
(a) Use the regression capabilities of a graphing utility to find a linear model for the points (t, In R). Write the resulting equation of the form In R = at + b in exponential form.
(b) Use a graphing utility to plot the data and graph the exponential model.
(c) Use the definite integral to approximate the number of liters of chemical released during the 4 hours.
