Answer

The population of New York is 19.4 million in 2010

Work Step by Step

In this function, t represents the number of years since 2000 and P represents the population in millions. Since the number 10 is inside the parentheses of the given equation, it must be t. Therefore the year it is referring to must be 2000+10 which equals 2010. The function is set to equal 19.4 so this is the P value. Therefore, the population of New York is 19.4 million in 2010.
