Determine the period
A sine function is represented as:
Where
By comparing:
and
So:
So, we have:
Hence, the period of the function is
I think it’s 5/14 not positive but pretty sure
For this case we have a function of the form:
Where,
A: initial population of bacteria
b: growth rate
x: number of hours
Since the diameter is double every hour, then:
We must now look for the value of A.
To do this, we evaluate an ordered pair of the graph:
For (1, 2):
Clearing A we have:
Then, the function is given by:
For after 9 hours we have:
Answer:
the diameter of the bacteria after 9 hours is:
Answer: medium 18. Range 6 ,25th percentile 17 , 75th percentile 20 ,IQR 3
Step-by-step explanation from the given figure, median is equal to 18, the range is equal to 21-15 equal to 6. The 25th percentile is equal to17 while the 75th is equal to 20. IQR then is equal to 20-17 equal to 3.
