Answer:
a) 
b) 6.84 million
c) 2028.52
d) 47 years
Step-by-step explanation:
a)Here we know standard exponential growth rate is
In this put t=0 and a(t)=6.27 million
thus we get a = 6.27 million
now 
this is equal to(in 2012)=
b)Put t = 6
we get
=6.84 million
c) 
take log both sides
we get 16.52 years
d) 
take log both sides we get 47 years to get double the current population.
You could solve this mathematically but i mean you could use your eyes.... Its most likely C

Hi,
The answer is 3/2 or 4
How I got my answer:
Just think that (2x+3) OR (x-4) has to be 0.
<span>
Than you can find it out with a simple +/- calculation. </span>
<span> 2x+3=0 x-4=0
x=-3/2 or 4</span>Hope this helps you.
Answer is b, hope you pass
So you will use slope formula which is m = (y2 -- y1) / (x2 -- x1)
-1 minus -7=6
13 minus -8=21
Remember it changes to a positive Keep,Change,Change
So its 6/21
Or 1/4
Ask questions if you still need help
