Lots of will mark brainliest this is a set of questions about exponential growth. 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. 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. explain the similarities and differences between your equations in (a) and (b). during what year will the population of city (a) first exceed that of city (b)? show all of your work and explain your steps. 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.

The city we will use is Orlando, Florida, and we are going to examine its population growth from 2000 to 2010.

Step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
