The file car_speed. mat(available on Canvas under HW4) contains the results of such a test, in the form of a time vector t (in seconds) and a speed vector v (in miles per hour).1) Write a completely genericMATLAB function that implements the quadratic polynomialregression technique. The function should have the formfunction [a, Syx, r]

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
