Transcribed Image Text:The number of bacteria in a refrigerated food product is given by N(T) = 2272 - 105T +53,
5 < T < 35 where T is the temperature of the food.
When the food is removed from the refrigerator, the temperature is given by T(t) = 4t + 1.9, where t is
the time in hours.
Find the composite function N(T(t)):
N(T(t))
