The population of a city is 45,000 and decreases by 2% each year, What will the population be after 15 years?

Correct  N₁₅ = 33,236

Step-by-step explanation:

Given:

N = 45,000

decrease 2% each year

N₁₅ = ? Population after 15 years

Now  N = 45,000

After first year   N₁ = 45,000 · 0.98

After second year N₂ = N₁ · 0.98 = (45,000 · 0.98) · 0.98 = 45,000 · 0.98²

After third year  N₃ = N₂ · 0.98 = 45,000 · 0.98² · 0.98 = 45,000 · 0.98³

After 15 years N₁₅ = 45,000 · 0.98¹⁵ = 45,000 · 0.739 = 33,235.6

N₁₅ = 33,236

God is with you!!!

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

one set of data has more variation than the other. hope this !
