Population a current census shows that the population of a city is 3.5 million using the formula p= aert find the expected popul
Yuki888 [10]

Answer: the expected population of the city in 30 years is 5470781

Step-by-step explanation:

The population growth is exponential. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 3.5 × 10^6

r = 1.5% = 1.5/100 = 0.015

t = 30 years

Therefore,

A = 3.5 × 10^6(1 + 0.015)^30

A = 3.5 × 10^6(1.015)^30

A = 5470781

Determine the values of "m" and "n" so the number would be in scientific notation:
Andreyy89

Answer:

79,000= 79•10^3

Step-by-step explanation:

so the amount of 0's = the power of 10.

In this situation there is 3 0's . so the power of ten will be 10^3

and then the number before the 0's will equal m

so m = 79 n = 3

And also (just as a side note) you can use the asterisk mark (*) as the multiplication symbol. on most keyboards the command is ctrl + 8. you can also use a bullet point (•) for multiplication symbol the command for that is alt + 0149
