Given:
The growth of a sample of bacteria can be modeled by the function
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,
where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.
Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.
Therefore, the number of total bacteria after 3 hours is about 3003.
Given:
The insect population function is:
Where x is the number of weeks.
To find:
The population after 4 weeks.
Solution:
The population of insect after x weeks is given by:
We need to find the population after 4 weeks.
After substituting , we get
The population after 4 weeks is 160. Therefore, the correct option is C.
Answer:
1.75=5n or 5n=1.75
Step-by-step explanation:
There are 5 n's on the bottoms so you are doing 5 times n (5n) and then 1.75 is on the top so the equation has to equal 1.75
The answer is ≈0.524... so, none of the above?
Start by moving the three to the other side of the equation. Do this by subtracting 3 from both sides, so you get 21x=11.
Next, divide both sides by 21. This will give you x=11/21, which is ≈0.524.
However, I do not see this as one of the answers. I get why you might be confused!
