The purpose of having flags on the stems of the notes is, this indicates that f<span>or each flag, the note's value is cut smaller by half. The more flags a note has, the shorter its length is. This has also the same purpose with beams. Notes smaller than quarter notes have flags or beams. Hope this answer helps.</span>

Answer: Hello there!
We knot that the model is of the form A(t) = A*e^(kt)
We also know that in 2004 the population was 6.3 billion and that in the next 100 years the population needs to be less than 25 billion. We want to find the maximum acceptable annual rate of growth.
Let's define t = 0 at 2004, this means that
A(0) = 6.3 billions = A*e^(k*0) = A
then A = 6.3 billions
and for finding the maximum k, we need to do the next step:
A(100) = 25 billion = (6.3 billion)*e^(k*100)
now we need to solve it for k:
25 billion = (6.3 billion)*e^(k*100)
25 = 6.3*e^(k*100)
e^(k*100) = 25/6.3
now we can aply the natural logaritm in both sides:
k*100 = ln(25/6.3)
k = ln(25/6.3)/100 = 0.014
So we know that if he population must stay below 25 billion during the next 100 years, then we need to use k < 0.014
