The human population of Earth was approximately 6 billion in 1998. If the rate of
population growth from then on was 2.3% per year, what would be the best
approximation for the human population (in billions) of Earth in 2020?

  9.89 billion

Step-by-step explanation:

At that rate of growth, the population is multiplied by 1.023 each year. After 22 years, the population would be ...

  6·1.023^22 ≈ 9.89 . . . billion

Let the equation for the population (P) growth be given by

P = P0ert, where P0 is the initial population in billioins at time t,

                           t is the number of years since 1987,

                           r is the rate of growth of population/year

In this case P0 = 5 billion and r = 0.02.  Putting these values into the equaation:

P = 5e0.02t

Year 1995 is 8 years after 1987, then the population would be

P = 5e0.02*8 = 5e0.16 ≈ 5.87 billion people

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
