Answer:
numbers
Step-by-step explanation:
Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
Given:
The growth of a sample of bacteria can be modeled by the function
![b(t)=100(1.06)^t](https://tex.z-dn.net/?f=b%28t%29%3D100%281.06%29%5Et)
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
![b(t)=100(1.06)^t](https://tex.z-dn.net/?f=b%28t%29%3D100%281.06%29%5Et)
Here, b(t) number of total bacteria after t hours.
Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.
![b(t)=100(1.06)^3](https://tex.z-dn.net/?f=b%28t%29%3D100%281.06%29%5E3)
![b(t)=100(1.191016)](https://tex.z-dn.net/?f=b%28t%29%3D100%281.191016%29)
![b(t)=119.1016 ](https://tex.z-dn.net/?f=b%28t%29%3D119.1016%0A)
Therefore, the number of total bacteria after 3 hours is 119.1016.
