Question

Need help with algebra please!

Answer 1

a. Do some research and find a city that has experienced population growth. Determine its population on January 1st of a certain year. Write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of exponential growth. Describe the variables and numbers that you used in your equation.
b. Find another city whose population starts larger than the city in part (a), but that during this same time experienced population decline. Determine its population for January 1st of the same year you picked for part (a). Write an exponential function to represent the city’s population, y, based on the number of years that pass, x after a period of population decline. Describe the variables and numbers that you used in your equation.
c. Explain the similarities and differences between your equations in (a) and (b).
d. During what year will the population of city (a) first exceed that of city (b)? Show all of your work and explain your steps.
e. During what year will the population of city (a) be at least twice the size of the population of city (b)? Show all of your work and explain your steps.

Answer 2

i don't know if i should do austin or denver

Answer 3

@whpalmer4 please help

Answer 4

Your choice of city really doesn't matter much, if at all. Focus on the rest of the problem statement.

Answer 9

Do Austin!!!

Answer 10

Austin is definitely growing. Assume the population is growing exponentially. Find out through a little online research what the population of Austin was in the year 2010, or now. Assume a growth rate of 3% per year.

How would you write an exponential function that models the growth of austin's population as a function of time, t, measured from 2010 (or measured from now)??
