A cup of coffee is heated in a microwave oven to a temperature of 65C. It is extracted and exposed to the environment that is at a temperature of 21C. For practical purposes it can be assumed that in the first 8 minutes the temperature of the coffee cup decreases uniformly at the rate of 3.5 degrees Celsius per minute.
a) Build the function that allows you to predict the temperature T for different values of time t measured in minutes.
b) How many minutes should you wait from your extraction from the oven to drink the coffee at a temperature of 40 degrees Celsius?
c) We consider this linear model working longer. What temperature does the coffee reach after 15 minutes? Is this possible?
Una taza de cafe se calienta en un horno de micro- ondas alcanzando una temperatura de 65 .C. Se extrae y se expone al medio ambiente que se en- cuentra a una temperatura de 21 .C. Para fines practicos se puede suponer que en los primeros 8 minutos la temperatura de la taza de cafe disminuye uniformemente a razon de 3.5 grados centigrados por minuto. a) Construye la funcion que permite predecir la tem- peratura 7 para diferentes valores del tiempo medido en minutos. b) Cuantos minutos se debera esperar a partir de su extraccion del horno para beber el cafe a una tem- peratura de 40 grados centigrados? c) Si consideramos este modelo lineal funcionando por mas tiempo Que temperatura alcanza el cafe a los 15 minutos? _Es esto posibleStep by Step Solution
