The number of bacteria in a refrigerated food product is given by N(T) = 20T² – 73T + 12, 4 < T < 34 where T is the temperature of the food. When the food is removed from the refrigerator, the temperature is given by T(t) = 4t + 1.8 , where t the time in hours. Find the composite function N(T(t)): N(T(t)) = Find the number of bacteria after 4 hours. Give your answer accurate to the nearest whole value. bacteria
