9.6 Exercise 5

Avg difficulty 2.5

Digital medical thermometers determine temperature by measuring the resistance of a semiconductor device called a thermistor (which has α=−0.06/°C\alpha = −0.06 / ° \text{C}) when it is at the same temperature as the patient. What is a patient’s temperature if the thermistor’s resistance at that temperature is 82.0% of its value at 37°C37 ° \text{C} (normal body temperature)?
