Initially (at t=0), the temperature is y(0) = 120. Determine the value of the constant A. Your Answer: 55 Instructors Comment: 1.0 2 Consider two armies, A and B, in battle. If the size of each army depends only on the size of the other army (i.e. the rate at which soldiers in one army are put out of action (killed or wounded) is proportional to the amount of fire the other army can concentrate on them), and assuming that no reinforcements arrive, then an appropriate system of differential equations to model this is: where m and k are postive constants, and A and B are the size of the armies.
