Question

Can some one explain to me what kinda problem this iz a citys population can be modeld by this equation p=130(1.03)^x where x is the number of years after january 1, 2000 for what value f x dose this model predict that the population of the city will be 170,000

Answer 1

This is what we call an exponential graph. If you have a graphing calculator, you can plug in this equation. Then look for the place where p = 170,000
If you don't have a graphing calculator, this can still be solved pretty easily.
Set the equation to:
170000=130(1.03)^x
This becomes
170000=133.9^x
Take the log of both sides.
log 170000=log 133.9^x
If you do this, your answer is: x = 2.45932701188
So after 2.46 years, the population will be at 170,000.
