Best Answer
Nt=N0*e(r*t)

Nt = Future Population

N0 = Starting population

r = growth rate

t= number of years.

Note: e is a constant equal to 2.71828

MANY missing variables.. like disease, pestilence.. war..

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the linear formula for population growth on earth?

it's not a linear formula its an exponential formula


Describe exponential growth and explain what is needed in order for this type of growth to continue?

Any time the RATE of increase is greater than one. For example : if a population were to double (note that 2 is greater than 1) each generation then it is referred to as exponential growth. Note also that there are now 7 billion people on Earth - exponential growth. What is "needed" for this kind of growth is an unlimited environment, since it does not exist in the real universe, exponential growth ALWAYS crashes.


Which of these BEST summarizes human population growth on the planet Earth?

Human population growth was gradual for most of the time people have existed, only in the last two centuries has population growth been rapid.


When does the exponential growth of a population?

When the food source is depleted, a new predator is introduced, or balance is attained. The earth tends to find balance for the most part. As far as an "intelligent" species such as humans goes, probably never. or When the organisms compete


When was exponential growth and decay invented?

They were not invented because they predated the first human beings. They existed at least millions of years before there was anyone to "invent" them.All novae produce radioactive elements and these decay exponentially. So exponential decay predates the formation of the solar system.I am not sure, but stellar fusion may be exponential. But, in any case, there are life forms on earth, like bacteria, that exhibit exponential growth. These bacteria, and therefore exponential growth, predate human beings by a few million years.They were not invented because they predated the first human beings.

At which rate of population growth is the coal supply on Earth expected to be used up the soonest?

High growth


When does the exponential growth of a population stop?

When the food source is depleted, a new predator is introduced, or balance is attained. The earth tends to find balance for the most part. As far as an "intelligent" species such as humans goes, probably never. or When the organisms compete


Why is exponential growth unlikely to happen for a very long time?

Because it doesn't take long for the organisms doing the growing to fill the entire Earth.


What is the most likely to limit human population growth?

the earth's carrying capacity


What would be a good title for a science project on earth?

Population growth and species survival.


What happened to earth's population in the last 200 years?

In the last 200 years, there has been a tremendous growth rate of the Earth's population. 200 years ago the population was about one billion. Today in 2014, the population is about 8 billion.


Why death rate is a factor that affecting the population growth?

The higher the death rate is, the fewer people there are on the Earth.
