- The table describes the cooling of a cup of coffee as it sits on your teacher’s desk in the math office. Time (min) 0 4 8 12 16 20 Temperature (celsius) 55 47 40 34 29 25
a) Calculate a, the cooling factor (rate at which the coffee cools per minute) of the coffee. Round your answer to two decimal places. b) Determine an equation for y, the temperature of the coffee in degrees Celsius after t minutes. c) Is your model a good predictor of the temperature of the coffee at any point in time? Explain.
