Answer:

5,120 bacterias

Step-by-step explanation:

Given the amount of bacteria after x hours modelled by the equation:

f(x) = 20(2)^x/12

Note that x is in hours not days

To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.

24hours = 1day

xhours = 4days

x = 24×4

x = 96hours

Substituting x = 96 into the equation

f(96) = 20(2)^96/12

f(96) = 20(2)^8

f(96) = 20×2^8

f(96) = 20×256

f(96) = 5,120

The number of bacteria that will be contained after 4days is 5,120bacterias
