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 ) ) =

= -41/9

Step-by-step explanation:

Given that:

= -2 (1/3 * 2/3) + 5

By solving the bracket first we get:

= -2 (2/9) +5

= -4/9 +5

Taking LCM to make denominator same:

Multiply 5 by 9/9 we get:

= -4/9 + 5*9/9

= -4/9 + 45/9

=(-4+ 45)/9

= -41/9

I hope it will help you!
