The number of bacteria in a refrigerated food product is given by N ( T ) = 26 T 2 − 126 T + 97 , 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 ) = 5 t + 1.4 , where t is the time in hours. Find the composite function N ( T ( t ) ) : N ( T ( t ) ) =
