Question

please I’m having trouble with for a 4 a& b . The first picture is my work

HS kt 00Ce 0-8001 L0 0 요) t20 ute thange in volume. 4. A thin plate is heated to 100 Cfor purposes of sterilization and then it is placed inside a room kept at a constant temperature of 20 C where i is allowed to cool down. The rate of change of the temperature of the plate, T,with respect to (a) Solve this initial value problem using the separation of variables method, and the fact that the plate's time, t, is given byT-T), where temperature is measured in degrees C,and time in minutes. dt temperature is 70'C after 20 min. (b) Check that your answer satisfies the DEQ and the initial condition. (c) Use Euler's Method to find the temperature of the plate after 15 min, using a step size of 5 min.
