(32 points) Equations describing a heating and a cooling processes are given by f1(t) = 100 (l (rum fz(t) = 40 (6'03"), where t represents the time in minutes. Using the Newton-Raphson's method (within four signicant digit accuracy), determine the time t at which both f1(t) and f2(t) reach the same temperature. Also, what is the temperature at that time t?
