(10 marks) A thermometer is placed outside. The initial temperature of the ther- mometer is 2°C. After 1 minute, the thermometer reads 5°C. After 2 minutes, the thermometer reads 6°C. What is the temperature outside? (Hint: Write the DE, solve it, use initial conditions, find expressions for C, ek and e2k in terms of the temperature outside. Relate them and solve for the temperature outside.)

A thermometer reading 7 degrees C is brought into a room with a constant temperature of 29 degrees C
A thermometer reading 7 degrees C is brought into a room with a constant temperature of 29 degrees C. If the thermometer reads 15 degrees C after 4 minutes, what will it read in 6 minutes? 11 minutes? So I guess I need to put into newton's law of cooling:u(t) = T + (u sub zero - T ) e^ktHow do I solve for k so can plug in my T's. and what is u sub zero? 7 degrees?
