Accоrding tо Newtоn's Lаw of Cooling, the temperаture T аfter t minutes of an object that has an initial temperature of T0 and is placed in a surrounding temperature of Ts is modeled by the equation below: ( T(t)=T_s+(T_0-T_s)e^{-kt} ) a) A cup of coffee that is initially 180 degrees F is placed on a table in a room with temperature 75 degrees F. After 1 minute, the coffee has cooled to 170 degrees. Find the value of k in the model. Round to the nearest tenth (one decimal place). {#1} b) How long will it take for the coffee to cool to 145 degrees F? Round your answer to the nearest minute. {#2}
