Question 8 (6 points) The table shows the temperature of a cup of coffee after it is poured into a cup and cools over a period of 10 minutes. Its temperature at the beginning is about 95°C. Rachel wants to drink the coffee when it is about 35°C, or about 15°C above room temperature (20-0). Time (min) Temperature (°C) 81.5 X UNO 55.6 NO 50.4 a. Explain why the temperature might follow an exponential decay curve as it approaches room temperature. b. Find an exponential model for the data. Use your model to determine when Rachel should drink her coffee.​
