Many highly developed countries, particular y in Europe, are finding that their population growth rates are declining and that a logistic function provides a much more accurate model than an exponential one for their population. The table gives B(t), the midyear population of Belgium (in millions), for years between 1980 and 2000, where t represents the number of years since 1980. Year 1980 1982 1984 1986 1988 1990 1992 1994 1996 1998 2000 B\") 9.85 9.86 9.86 9.86 9.88 9.96 10.04 10.11 10.15 10.18 10.19 (a) Use a graphing calculator (TI-89 or better) to nd a logistic model for Belgium's population. B(t) = At what value will the population level off? (Round your answer to two decimal places.) million
