(10 pts) Follow the steps to solve the IVP: x ′′ − x ′ − 6x = (t − 3) cos(πt) , x(0) = 1, x ′ (0) = 3. a. Find the Laplace transform, ℒ{x(t)}, of the solution. Do not perform partial fraction decomposition yet. b. Solve for the solution, x(t), using the inverse Laplace transform. Use h(t − c) for the Heaviside function.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
