Given that, A = 7e0.007t
Comparing with A = A0ekt, we get,
A0 = 7, k = 0.007
.
(a) So country's growth rate is (0.007 * 100%) = 0.7%
In 2 Use the formula t= that gives the time for a population, with a growth...
In 2 Use the formula t= that gives the time for a population, with a growth rate k, to double, to answer the following questions. The growth model A=70.0071 describes the population, A. of a country in millions, tyears after 2003. a. What is the country's growth rate? The half-life of a certain tranquilizer in the bloodstream is 38 hours. How long will it take for the drug to decay to 84% of the original dosage? Use the exponential decay...

Please answer correctly The exponential model A = 669 0.031 describes the population, A, of a country in milions, tyears after 2003. Use the model to determine when the population of the country will be 1099 million The population of the country will be 1099 million in I. (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.)
Complete the table shown to the right for the population growth model for a certain country. 2003 Population (millions) 51.3 Projected 2027 Population (millions) 40.2 Projected Growth Rate, k (Round to four decimal places as needed.)
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...
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.)
Complete the following table Population Growth Rate, k Doubling Time, T Country A 2.6% per year Country B 26 years Population Growth Rate, k Doubling Time Country A 2.6% per year !years Country B % per year 26 years Round doubling time to the nearest whole number and round growth rate to the nearest tenth.)
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 exponential models describe the population of the indicated country, A, in millions, tyears after 2006. Which country has the greatest growth rate? By what percentage is the population of that country increasing each year? A = 28.3 0.0231 Country 1: Country 2: Country 3: Country 4: A= 1080.3 e 0.013 A=148.26 -0.0040 A = 132.7 0.0031 Country has the greatest growth rate. The population of that country is increasing by % each year. (Round to the nearest tenth as...
