Find the explicit solution of the ivp xy . Problem 5 (15+5 points) (a) find an implicit solution of the ivp y = x + 2. On thanksgiving day you walk into the kitchen and see that your little brother has already taken the turkey out of the oven. On the meat thermometer you see that its current core temperature is 120 f. After 10 minutes the temperature has dropped to 100 f. Here you don"t have to evaluate logarithms, but you have to solve the de. 8 (b) your brother tells you that he took the turkey out 10 minutes before you walked into the kitchen. Determine if the turkey had reached a safe temperature of at least 165 f before it was taken out of the oven.
