Answer:
The rate of change is 0.08 and the initial value is 24.
Step-by-step explanation:
1. You have the following formula:
2. It has the form of a equation of the line, which is:
Where 
is the slope, which gives the rate of change and 
is the y-intercept (The initial value, when 
)
3. Therefore, the rate of change of the given formula is:
4. And the initial value is:
That is true i do believe
Answer:
390 Millions of bacteria particles by the end of one week.
Step-by-step explanation:
The Bacteria Growth Rate Formula is: ---> N (T) = N (0) * (1 + R) ^tT
N (0) = # of bacteria present during the beginning of the experiment
Variable R= Growth rate
Variable T= Time taken / elapsed.
Substitute the #'s for N (T)
N (0) and T from the given description
We then get the value of variable R.
220 = 20 * (1+R) ^ (24 hrs)
When solving for R, we get R = 0.105074
1 week= (7 x 24 = 168) hrs
We need to plug in the solutions
Therefore
N (168 hours) = 20 * (1+0.105074) ^168
Which is around 390 millions.
So now we know that there will be 390 millions of bacteria particles at the end of 1 week
