The population of Las Vegas, Nevada in 2000 was 478,000 and is increasing at the rate of 6.28% per year. At this rate, when will the population reach 1 million people?

Impossible question.
Considering that Las Vegas's population has considerably shrunk due to the recession, this question makes no sense today. 
The 2010 population was 583,756
