This document discusses exponential growth and decay models, including Newton's Law of Cooling. It contains 4 objectives: 1) modeling bacterial growth using an exponential function and calculating time until the population triples or doubles again, 2) is blank, 3) uses Newton's Law of Cooling to find the time an object takes to reach temperatures of 50° and 35° after cooling from 75° to 30° ambient temperature, and notices the temperature decreases over time, and 4) is blank.
