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?
Prehistoric cave paintings were discovered in a cave in France. The paint contained 21% of the original carbon-14. Use the exponential decay model for carbon-14 A=AD -0.0001211 to estimate the age of the paintings The paintings are approximately years old. (Round to the nearest integer.) The half-life of a certain tranquilizer in the bloodstream is 38 hours. How long will take for the drug to decay to 84% of the original dosage? Use the exponential decay model AA to solve....

The half-site of a certain tranquilizer in the bloodstream lis 21 hours. How long will it take for the drug to decay to 95% of the original dosage? Use the exponential decay model, A-ASEM to solve hours (Round to one decimal place as needed)
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.)
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 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.)
