Question: User: 2. Cooling coffee The temperature of coffee in a room is modelled by T(t) = 21 + 69(0.86)^t, where T is in °C and t is time in minutes. a. What was the coffee's initial temperature? b. What temperature does the model approach over time? Explain its meaning. c. Find the temperature after 8 minutes. d. After how many minutes will the coffee first be below 45°C? Graph/shape: A temperature-vs-time exponential decay model is shown in the top-center of the page; the equation T(t) = 21 + 69(0.86)^t is highlighted near the top-left/center, with no plotted axes visible.
