As of the year 2000, the African nation of Chad had one of the highest population growth rates in the world, 3.3%/ year. At the other extreme in 2000, the United Kingdom had one of the lowest (positive) growth rates, 0.1%/year. (There are countries with zero or with negative growth rates.) (a) In 2000 the sizes of the populations of Chad and the United Kingdom were 8.0 million and 59.8 million, respectively. Write the exponential growth law for each country, letting t = 0 correspond to 2000. Chad N(t) = 59.80.001t million X United Kingdom N(t) = 62.86138 million X (b) Assuming exponential growth, when would the two countries have populations of the same size? Hint: Equate the two expressions for N(t) obtained in part (a). (Round your answer to the nearest whole year.) t ~ 2063 X yr
