Question 437480: The world population P(t), in billions, t years after 1990 can be approximated by: P(t)=3.335(1.016)^t In what year will the world population reach 8 billion? and what is the doubling time? Any help would be greatly appreciated!

^t\ =\ 8)
^t\ =\ \frac{8}{3.335})
^t\ =\ \ln\left(\frac{8}{3.335}\right))
\ =\ \ln\left(\frac{8}{3.335}\right))
}{\ln(1.016)})
All that is left is calculator work.
Doubling time:
^t\ =\ 2)
Do this one the same way.

My calculator said it, I believe it, that settles it
