Answer:
5 generations
Step-by-step explanation:
Data provided in the question:
Number of bacteria at the beginning of a time interval
, B = 4
Number of bacteria at the end of the time interval, b = 128
Now,
The relation between the bacteria at the beginning, bacteria at the end and the number of generations (n) is given as:
b = B × 2ⁿ
Therefore,
on substituting the respective values, we get
128 = 4 × 2ⁿ
or
2ⁿ = 32
or
2ⁿ = 2⁵
or
n = 5
hence,
5 generations
Answer:
3n>15
Step-by-step explanation:
So basically, this three times a number, 3n, is greater than 15. So, this is 3n>15.
