After working this problem out, we know that 3x + 1 is not a total factor of the dividend, because there is a remainder.
When you divide a polynomial by another polynomial, if there is a remainder, it is not a complete factor.
<h3><u>After dividing, we are left with: 2x^3 - 2x - 4 + (3/(3x + 1))</u></h3>There is a remainder of 3.
Option B: 256 is the diameter of the bacteria after 8 hours.
Explanation:
From the given, it is obvious that the graph is an exponential function.
The general formula is given by,
Where a is the initial population,
b is the growth rate and
x is the number of hours.
It is given that the diameter of the bacteria doubles every hour.
Then, we have,
Let us substitute the coordinate (0,1) and , we get,
Thus, substituting and
in the general formula
, we have,
We need to determine the diameter of the bacteria after 8 hours.
Let us substitute x = 8 in the equation , we get,
Thus, the diameter of the bacteria after 8 hours is 256
Hence, Option B is the correct answer.
