Answer:
Initial bacterias = 6006000
Altought I believe is safe to assume that the values were 192,000 and 384,000 instead of 192,192,000 and 384,384,000, in that case the initial bacterias is 6000
Step-by-step explanation:
A exponential growth follows this formula:
Bacterias = C*rⁿ
C the initial amount
r the growth rate
n the number of time intervals
Bacterias (55 hours) = 192,192,000
Bacterias (66 hours) = 384,384,000
If you divide both you can get the growth rate:
So with that r = 2 and each time interval correspond to 11 years
Then replacing in one you can get the initial amount of C
The standard form of a line is in the form
A, B and C are integers, and A is positive. Let's start with multiplying the whole equation by 3 to get rid of denominators:
Subtract 3y from both sides:
Which of course is equivalent to
Which is the standard form, given the coefficients A=1, B=-3, C=6.
