Which inequality is represented by this graph? 0 - 345> x O 0 -34.5 0 -355 cx
1 answer:
Answer:
Step-by-step explanation:
If x is the white dot on the graph:
From what it looks like, x is right between -35 and -34 x (which is -35.5).
If that is the case then none of the answers are correct since -35.5 is <u>equal or less</u> than x. (the sign looks like this: "" )
But if you have to choose one of the answers then number 4 (-35.5 < x) would be closest.

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.
