Human population growth and density have a profound impact on health and medicine. If the human population size in 2008 was 6.8 billion, what is the projected population size in the year 2018? Assume the population is growing exponentially, and the growth rate (r) is 0.014.

Respuesta :

Answer:

Step 1:

Identify the variables.

Inititial value (a) = 6,800,000,000

Growth rate (r)= 0.014

x = 10

y = ?

Step 2:

Substitute.

y = 6,800,000,000× (1 + 0.014)^10

y =6,800,000,000× (1.014)^10

y = 7813200000

Which is rounded to 7.8billion population.

Therefore,

After 10 years, there will be 7.8 billion people on Earth.

Therefore the increase in population growth and density would have a profound impact on health and medicine.
