Answer:
10 teeth must go on the driven gear
Step-by-step explanation:
Let the number of teeth be x
In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that
17:5 = 34:x
∴ 10 teeth must go on the driven gear
hence ratio = 34:10
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.
