QUESTION 5 d?y dy a) Solve the differential equation 2 +y%3D5×+3. dx2 dx b) Greenland had a population of 55000 in 1980 and a population of 78000 in 1990. Assume that the rate of population growth is proportional to its population at any time t. Calculate the population of Greenland in the year 2020. c) A hard-boiled egg at 98°C is put under a constant temperature 18°C running water to cool. After 5 minutes, the egg's temperature is found to be at 38°C. Calculate the time taken for the egg's temperature to reach 20°C. [Hint: Use Newton's Law of Cooling]
