Answer: Ron tower's
Step-by-step explanation:
Given
Ron tower has a base of
Freddy tower has a base of
Suppose the tower is in the shape of a square prism
The volume of Ron and Freddy tower is
The volume of a square-based prism is
The height of Freddy tower is
Thus, the height of Ron's tower is more than Freddy's tower by
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.
