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]

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
