Question

The population of the world in 1975 was 15 billion and the relative growth rate was estimated at 0.15 percent per year. Assuming that the world population follows an exponential growth model, find the projected world population in 2018.

Answer #1

The population of the world in 1990 was 50 billion and the
relative growth rate was estimated at 0.5 percent per year.
Assuming that the world population follows an exponential growth
model, find the projected world population in 2018.

Q1In May 2020, the world population was 7.8 billion and was
growing at a rate of 1.08 percent. Project what the world
population would be in 2025, 2050, and 20100 at this constant
growth rate.

Question 1-2: Given a 2011 population of 7 billion and a 2020
population of 7.8 billion, calculate the average annual growth rate
over that 9-year period.

The size of the world population at the beginning of 1988 was
approximately 5.14 billion. At the beginning of 1989, it was 5.23
billion. Assume that the population follows a natural growth model.
How long will it take for the population to double?

The population of the world was about 5.3 billion in 1990 (t =
0) and about 6.1 billion in 2000 (t = 10). Assuming that the
carrying capacity for the world population is 50 billion, the
logistic differential equation
dP =kP(50−P)dt
models the population of the world P(t) (measured in billions),
where t is the number of years after 1990. Solve this differential
equation for P(t) and use this solution to predict what the
population will be in 2050 according...

1) a) The fox population in a certain region experiences
exponential growth with a relative growth rate of 8% a year. In
2013, it was estimated that the population was 18, 000. (a) Find a
function that models the population t years after 2013. (b) Use the
function above to estimate the fox population in the year 2021. (c)
After how many years will the fox population reach 25, 000?
b) Two observers simultaneously measure the angle of elevation of...

Part A) Solve one of the four world population problems and
explain your process using the following: The growth of the world
population can be described by the equation A=A0ert where t is
measured in years, A0 is the population of the world at the time t
= 0, and r is the annual growth rate, and A is the population at
time t. 1) In 1960, the world population was about three billion
people and the growth rate was...

Assume the world population will continue to grow exponentially
with a growth constant k=0.0132k=0.0132 (corresponding to a
doubling time of about 52 years),
it takes 1212 acre of land to supply food for one person, and
there are 13,500,000 square miles of arable land in in the
world.
How long will it be before the world reaches the maximum
population? Note: There were 6.06 billion people in the year 2000
and 1 square mile is 640 acres.
Answer: The maximum...

Company A is going to make an investment of $15 billion on its
new production. The production department has estimated projected
volume is 100,000 units per year, variable costs per unit at
$300,000, and fixed costs are $3 billion per year. The project is
estimated to be for 10 years and the profits are taxed at a rate of
50%. Assume that Company A has no liability outstanding and an
opportunity cost of capital of 10%.Please calculate the NPV of...

Suppose that every $566 billion of dead capital reduces the
average rate of growth in worldwide per capita real GDP by 0.3
percentage points.
If there is $8 trillion in dead capital in the world,
calculate by how many percentage points the existence of dead
capital will reduce average worldwide growth of per capita real
GDP. ___ percent.

The population of a bacterial culture develops with constant
relative growth rate of 0.9758 per member per day. Initially the

days.
