Answer:

Step-by-step explanation:
we know that
The exponential function is of the form

where
a is the initial value
b is the base
In this problem we have
a=200 birds
b=100%+4%=104%=104/100=1.04
substitute

Let change of variables

where
b is the amount of birds in the flock
d is the number of days since the 200 birds started
Answer:
All you have to do is remember the equation: 2 *pi * r
or d * pi
Step-by-step explanation:
2R and d are the same thing
It is 0.067/=0.67/10=6.7/100=6.7%
answer is 6.7%
