2. The following table shows the estimated populations and annual growth rates for four countries in the year 2000. Find the expected population of each country in 2025, assuming their annual growth rates remain steady. Country Australia Population in 2000 19,169,000 Growth Rate 0.6% China 1,261,832,000 0.9% Mexico 100,350,000 1.8% Zaire 51,965,000 3.1% (SHOW WORK) 5. Astronomers classify stars according to their brightness by assigning them a stellar "magnitude." The higher the magnitude the dimmer the star. The dimmest stars visible to the naked eye have stellar magnitudes of 6. The table below shows the relative brightness of different stellar magnitudes. Stellar Magnitude Relative Brightness 2 3 4 5 6 100 40 16 6.3 2.5 1 a. Find an equation that gives the relative brightness in terms of stellar magnitude. b. Use this equation to find the relative brightness of a star with magnitude 9. (SHOW WORK)
