19. The temperature of a cooling liquid over time can be modelled x 130 by the exponential function T(x) = 60/ + 20, where T(x) is the temperature, in degrees Celsius, and x is the elapsed time, in minutes. a) Graph the function. b) Determine how long it takes for the temperature to reach 28°C. c) Check the accuracy of your answer.

(SUB-PART C ONLY PLEASE) Each row represents an experimental “run” (in this case, averaged sample of mango wine). Column A shows the run number; Column B shows the percentage of ethanol; Column C shows the amount of glycerol (in g/L); Column D shows the amount of acid (in g/L); Column E shows the temperature of the run (in °C); and Column F shows the pH of the run.
