One tool used in genetics is called a pedigree chart, are there any advantages to using this tool? The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an exponential growth function to model this situation. Then find the population in 2009.

A = 236,000 (1.04) ^t

population in 2009 : 335,902 people

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t

Where:

p = original population

r = growing rate (decimal form) = 4/100 = 0.04

t = years passed from 2000

A = population after t years

Replacing with the values given:

A = 236,000 (1 + 0.04) ^t

A = 236,000 (1.04) ^t

Population in 2009.

t = 2009-2000 = 9

A = 236,000 (1.04) ^9

A = 335,902 people
