The number of bacteria, b, in a refrigerated food is given by the function b(t) = 15t2 - 60t + 125, where t is the temperature of food in degrees fahrenheit. the function t(h) = 3h + 4 gives the temperature, t, of the food h hours after being removed from the refrigerator. find the number bacteria in the food in h hours.

Step-by-step explanation:

Given: The number of bacteria, B, in a refrigerated food is given by the function   , where t is the temperature of food in degrees Fahrenheit.

The function gives the temperature, t, of the food h hours after being removed from the refrigerator.

Now, the number bacteria in the food in h hours is given by:-

So, The number bacteria in the food in h hours is given by:

3; 9 is 8 to -4

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
