population increase of a country that clearly has no birth

00:18

control Which of the following best characterizes the model for

00:33

zero people there Then the population increase of five million

in nineteen ninety like everyone migrated there gave the country

00:43

million more people so a total of fifteen million gained

00:46

so far My goodness that's a big oppel Population increase

goes like five ten fifteen twenty twenty five Total population

00:54

is five fifteen thirty fifty seventy five Kind of taking

00:57

a little bit so the total population is exponentially increasing

01:02

But that's not quite exponentially interesting but at least we're

01:05
