Label the form next to the equation.Problem 6Verify that y=2+Ce-2x2 is a family of solutions for the differential equation dydx+4xy=8x by taking the derivative of the solution curve and plugging into the differential equation. Problem 7Use Euler’s method with step size h=12 to approximate the solution to the initial value problem dydx=x-y2, y(1)=2, at x=2.Problem 8Determine the general solution for the non-linear, first-order differential equation dydx=e3x+2y.Problem 9Find the general solution for the linear, first-order differential equation y'-1xy=x2 exProblem 10The population of a species grows at a rate proportional to the population present at time t. If the initial population of 500 doubles over 5 years, what will the population be at t=12? Use the differential equation dPdt=kP.Problem 11A tank contains 200 liters of fluid in which 30 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then added into the tank at a rate of 4 liters per minute. The well-mixed solution is pumped out at the same rate. If represents the amount of salt in the tank at any time minutes after the process begins, then the first-order differential equation that models this situation is given by dAdt=4-A50. Find the particular solution for A(t).Problem 12A small metal bar is heated using a pot of boiling water (100 °C). The initial temperature of the metal bar is 20 °C. It is known that the temperature increases by 2 °C after the first minute. Use Newton’s Law of Cooling to find the particular solution.You do not need to submit anything HERE for these problems.
