The populations of termites and spiders in a certain house are growing exponentially. The house contains 80 termites the day you move in. After four days, the house contains 150 termites. Three days after moving in, there are two times as many termites as spiders. Eight days after moving in, there were four times as many termites as spiders.
How long (in days) does it take the population of spiders to triple?

The populations of termites and spiders in a certain house are
growing exponentially. The house contains 110 termites the day you
move in. After four days, the house contains 195 termites. Three
days after moving in, there are two times as many termites as
spiders. Eight days after moving in, there were four times as many
termites as spiders.
How long (in days) does it take the population of spiders to
triple? (Round your answer to one decimal place.)

The cities of Abnarca and Bonipto have populations that are
growing exponentially. In 1980, Abnarca had a population of 24,000
people. In 1990, its population was 30,000. Bonipto had a
population of 31,000 in 1980. The population of Bonipto doubles
every 55 years. (Round your answers to the nearest whole
number.)
(a) How long does it take the population of Abnarca to
double?
(b) How long will it take for Abnarca's population to equal that of
Bonipto?

The cities of Abnarca and Bonipto have populations that are
growing exponentially. In 1980, Abnarca had a population of 23,000
people. In 1990, its population was 28,000. Bonipto had a
population of 35,000 in 1980. The population of Bonipto doubles
every 55 years.
(a) How long does it take the population of Abnarca to
double?
(b) How long will it take for Abnarca's population to equal that
of Bonipto?

Consider a population that begins growing exponentially at a
base rate of 4.8% per year and then follows a logistic growth
pattern. If the carrying capacity is 60 million, find the actual
fractional growth when the population is at 10 million, 30
million, and 50 million.

a) You have an exponentially-growing population of rodents, with
an annual λ of 1.35.
Calculate the number of individuals added to the
population in a given month when
there are 250, 500, 1000, 5000, or 10,000 individuals to start
with. (2pts)
b) Now impose density dependence on
the population with a logistic model in which K = 6500 individuals.
Again, calculate the number of individuals added to the
population in a given month when there
are 250, 500, 1000, 5000,...

Populism is a development that has exponentially been growing.
Yet, globally there is much criticism of populist leaders. In
preparation for this discussion, take a look at the concept of
populism and Google it. Also, Google a couple of global leaders who
are identified as populist.
Now, armed with that information, particularly in the midst of
the critiques of democracy being taken away from the people by
populist leaders, how do you think the concept of groupthink plays
out in...

The lifetime of a certain kind of battery is
exponentially distributed, with an average lifetime of 25
hours
4. Find the value of the 60th percentile for the
lifetime of one battery. Remember units!
5. Write an interpretation (a sentence) of the 60th
percentile for the lifetime of one battery. Your interpretation
should include the value of the 60th percentile with correct
units.
6. We are interested in the average lifetime of 16 of
these batteries. Call this random variable....

Discuss the nature of an exponentially growing quantity and
explain what the term doubling time means. Explain why the problem
of exponential growth is easily overlooked. Discuss some of the
differences in the factors affecting population growth in the U.S.
25 or 50 years ago compared to now. Discuss demand for resources in
a growing population in one area (e.g. town, or county, or country)
and globally (world economy, resources, food production supply and
demand, living space, etc).
