Recall newton’s law of cooling: the temperature of an object changes at a rate directly proportional to the difference between the ambient temperature and the object itself. use newton’s law of cooling to solve the following: an initial thermometer reading 75 f is taken outside where the temperature is 20 f . it is observed that 4 minutes later, the thermometer reads 30 f . find the thermometer reading 7 minutes after it was taken outside. (note: to receive full credit, you must write down the associated differential equation and solve it)
