If the population of a certain county was 100,000 in 1998 and 110,431 in 2008 and...
In the year 2000, the population of a certain country was 278 million with an estimated growth rate of 0.5% per year. Based on these figures, find the doubling time and project the population in 2100. Let y(t) be the population of the country, in millions, t years after the year 2000. Give the exponential growth function for this country's population. y(t) = 1 (Use integers or decimals for any numbers in the expression. Round to four decimal places as...
the
population P (in thousands) of a certain city from 2000 through
2008 can be modeled by
p=280.84e^kt
where t is the year with t=0
corresponding to 2000.
in 2006 the population was about 360,000.
(a) finf the value of k for the model. round your result to
four decimal places

In the year 2000, the population of a certain country was 276 million with an estimated growth rate of 0.5% per year a. Based on these figures, find the doubling time and project the population in 2120 b Suppose the actual growth rates are ust 0.2 percentage points lower and higher than 0.5% per year 0.3% and 0.7%). What are the resulting doubling times and projected 2120 population? a. Let y(t) be the population of the country, in millions, t...
This exercise uses the population growth model. The fox population in a certain region has a relative growth rate of 5% per year. It is estimated that the population in 2013 was 16,000. (a) Find a function n(t) = n0ert that models the population t years after 2013. n(t) = (b) Use the function from part (a) to estimate the fox population in the year 2020. (Round your answer to the nearest whole number.) (c) After how many years will...
At the beginning of a study, a certain culture of bacteria has a population of 730. The population grows according to a continuous exponential growth model. After 5 days, there are 949 bacteria. (a) Lett be the time (in days) since the beginning of the study, and let y be the number of bacteria at timer. 8 On Write a formula relating y tot. Use exact expressions to fill in the missing parts of the formula Do not use approximations....
The populations P (in thousands) of a certain city from 2000 through 2008 can be modeled by P = 281.81ekt, where t is the year, with t = 0 corresponding to 2000. In 2006, the population was about 364,000. (a) Find the value of k for the model. Round your result to four decimal places. k= (b) Use your model to predict the population in 2015. (Round your answer to the nearest person.) P= thousand
The populations P (in thousands) of a certain city from 2000 through 2008 can be modeled by P = 1111.9ekt where t is the year, with t = 0 corresponding to 2000. In 2002, the population was about 1,300,000. (a) Find the value of k for the model. Round your result to four decimal places. k= (b) Use your model to predict the population in 2015. (Round your answer to the nearest person.) P= thousand
This exercise uses the population growth model. The count in a culture of bacteria was 400 after 2 hours and 25,600 after 6 hours. (a) What is the relative rate of growth of the bacteria population?

(Round your answer to the nearest whole number.) 200 x bacteria (c) Find a function that models the number...
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...
The population of Lost Town was 25, 150 in 2010 and 27,351 in 2016. Assuming an exponential growth rate, find the k value to 4 decimal places of the exponential growth equation with Po = 25, 150. Then predict the population of Lost Town in 2021. Round the predicted population to the nearest whole number. Answer with a complete sentence. Show all work.
