3. Using the population model for Kansas, A = 2.9e0.006, where A is the population in...
5. An approximate formula for the population (P, in millions) of the state of Kansas since 1970 is: P-2.256e where t is the number of year since 1970. Determine how long it will take the state of Kansas to reach a population of 2.54 million (round to the nearest year) and what year wil that be?
The exponential model A = 666.1 e 0.024t describes the population, A, of a country in millions, t years after 2003. Use the model to determine when the population of the country will be 807 million. The population of the country will be 807 million in (Round to the nearest year as needed.)
The exponential model A=980.92.004 describes the population, A. of a country in millions, t years after 2003. Use the model to determine when the population of the country will be 1071 million The population of the country will be 1071 million in I (Round to the nearest year as needed.)
The population of a city is modeled by the equation P(t) = 218,884e0.25t where t is measured in years. If the city continues to grow at this rate, in approximately how many years will it take for the population to reach one million? (Round your answer to two decimal places.)
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...
The population P of Texas6 (in millions) from 2001 to 2010 can be approximated by the model p=20.871e^0.0188t , where t is the year, with t=1 corresponding to 2001. According to the model, where year will the population reach 30 million? To find answer, do you have to use interpolation or exterpolation?
.. In 2000, the population of a country was approximately 5.73 million and by 2028 it is projected to grow to 8 million. Use the exponential growth model A=Age, in which t is the number of years after 2000 and A, is in millions, to find an exponential growth function that models the data, By which year will the population be 15 million? Population (millions) b. 12 Projected 9 2000 6 5,730,000 3- 0- 1950 1970 1990 2010 2030 2050...
a. 12 In 2000, the population of a country was approximately 5.61 million and by 2069 it is projected to grow to 12 million. Use the exponential growth model A = Ag ekt, in which t is the number of years after 2000 and Ao is in millions, to find an exponential growth function that models the data. By which year will the population be 13 million? Projected b. Population (millions) 2000: 5,610,000 6- 0+ 1950 1970 1990 2010 2030...
The population of a country dropped from 52.7 million in 1995 to 45.2 million in 2008. Assume that P(t), the population, in millions, t years after 1995, is decreasing according to the exponential decay model a) Find the value of k, and write the equation. b) Estimate the population of the country in 2019. c) After how many years will the population of the country be 1 million, according to this model? a) Select the correct answer below and fill...
s method and h-0 5 TTOP Tor the value at t 2.0 obtained by Euler's method Report results to two decimal places 5. The population of a certain type of bacteria, kept in a Petri dish at a constant 25 C,changes according to the Limited Growth Model. An initial population of 10 million bacteria increases to 15 million carrying capacity, M, of this system is 40 million bacteria. (Recall: for this model the rate of population with respect to time,...
