Consider a population of 10,000 cranes that is decreasing exponentially by 300 cranes per year. (Type out your work and report units.) What is the intrinsic rate of increase, r? A crane expert estimates that the minimum viable population size is 1000 cranes. If nothing changes, how long will it take for this population to reach the minimum viable population size?

The population of a southern city follows the exponential law. If the population doubled in size over 25 months and the current population is 20,000, what will the population be 3 years from now? What will the population be 3 years from now? The population will be approximately people. (Do not round until the final answer. Then round to the nearest whole number as needed)
QUESTION 2 A population P(t) (where t is the time in years) undergoes yearly seasonal fluctuations such that the rate of population growth is proportional to a fraction rP(t) of the total population, where r = cos 2rt Initially, the population is P After 3 months (1e 3/12 years), the population grows to 110% of its imitial sıze maximum value that P(t) can attain? At what tıme(s) does P(t) attan its maxımum? What is the [12] QUESTION 2 A population...

Real per capita GDP in Singapore in 1960 was about $350, but it doubled to about $700.00 by 1981. a. What was the average annual economic growth rate in Singapore over the 21.00 years from 1960 to 1981? (NOTE: Round this to two places past the decimal point.) % b. Per capita real GDP doubled in Singapore again in only seven years, reaching $1400.00 by 1988.00. What was the average annual economic growth rate between 1981 and 1988.00? (NOTE: Round...

The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial population P. has doubled in 5 years. Suppose it is known that the population is 11,000 after 3 years. What was the initial population Po? (Round your answer to one decimal place.) Po= What will be the population in 10 years? (Round your answer to the nearest person.) persons How fast is the population growing at...
