Find the general solution of the given differential equation, and use it to determine how solutions behave as t - co. + = 3 cos(4t), t> 0 t. NOTE: Use c for the constant of integration. y Solutions converge to the function y =Solve the initial value problem. 2 ,y(0)=v Let be the value of a for which the transition from one type of the 3y'2y=e long-run behavior to another occurs. Find the critical value (1.3 exactly. Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton's law of cooling. If the coffee has a temperature of 160 F when freshly poured, and 1 min later has cooled to 150 F in a room at 70 F, determine when the coffee reaches a temperature of 120 F. Note: Enter the exact symbolic expression for the asked time. The coffee reaches the temperature 120 in minutes.Suppose that a certain population has a growth rate that varies with time and that this population satisfies the differential equation dy dt = (0.4 + sint) NOTE: Round your answers to two decimal places. a) If y(0) = 1, find (or estimate) the time 7 at which the population has doubled. Choose other initial conditions and determine whether the doubling time ~ depends on the initial population. The doubling time is T = The doubling time Choose one depend on the initial population.b) Suppose that the growth rate is replaced by its average value 10 Determine the doubling time 7 in this case. In this case, T = c) Suppose that the term sin t in the differential equation is replaced by sin (27t); that is, the variation in the growth rate has a substantially higher frequency. What effect does this have on the doubling time ? In this case, T =
