A cup of tea is cooling in a room that has a constant temperature of 70 degrees Fahrenheit (F). If the initial temperature of the tea, at time t=0 minutes, is 200 F and the temperature of the tea changes at the rate: R(t) -6.89e^(-.053t) degrees Fahrenheit per minute, what is the temperature, to the nearest degree, of the tea after 4 minutes? 2. On the closed interval [2, 4], which of the following could be the graph of a...

(1 point) Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Suppose t is time, T is the temperature of the object, and Ts is the surrounding temperature. The following differential equation describes Newton's Law dT/dt=k(T−Ts), where k is a constant. Suppose that we consider a 95∘C cup of coffee in a 25∘C room. Suppose it is known that the coffee cools at a...

Your 300 mL cup of coffee is too hot to drink when served at 90°C. An ice cube, taken from a −20°C freezer is used to cool your coffee to a pleasant 60°C. Assume that you have a well-insulated cup. a. Provide the statement of energy conservation for this closed “coffee-ice” system. b. What is the heat lost by coffee in bringing down the temperature to 60°C? c. How much heat is consumed in converting ice to water at 0°C?...

Problem 7-19 (Algo) A cafeteria serving line has a coffee urn from which customers serve themselves. Arrivals at the urn follow a Poisson distribution at the rate of 2.5 per minute. In serving themselves, customers take about 16 seconds, exponentially distributed. a. How many customers would you expect to see, on average, at the coffee urn? (Do not round intermediate calculations. Round your answer to 2 decimal places.) b. How long would you expect it to take to get a...

13. Podunk City has two coffee shops and everyone in the city buys one cup of coffee per day. The owners of these shops can serve Maxwell House Coffee or they can serve Le Fru FruGourmet Coffee (simplifying assumption—suppose they charge the same price for either cup of coffee). Assume that customers strictly prefer Le Fru Fru coffee so that if one firm offers Le Fru Fru and the other doesn’t, all customers will go to the Fru Fru shop...
