A cup of coffee is cooling on the counter. The initial temperature of the coffee is 100° F. It takes 6 minutes for the coffee to cool to 80°F in a room with surrounding air temperature of 60°F. D) Find the value for k ( the constant of proportionality) in EXACT form AND write the equation representing the particular solution for the given scenario. NO CALCULATOR. E) Using the particular solution, determine the temperature of the coffee after 4 minutes. SHOW the equation you are inputting into your calculator. Round to the nearest degree.
