sible The growth of a certain species (in millions) since 1960 closely fits the following exponential function where t is the number of years since 1960. A(1)=3100 e 0.01661 a. The population of the species was about 3670 million in 1970. How closely does the function approximate this value? b. Use the function to approximate the population of the species in 2000. (The actual population in 2000 was about 6132 million) c. Estimate the population of the species in the year 2015. a. Choose the correct answer below. O A. The population of the species in 1970 is approximately 3660 million. This is fairly close to the actual value of 3670 million, because the percentage difference is very small. O B. The population of the species in 1970 is approximately 3660 million. This is not a close appoximation to the actual value of 3670 million, because the difference in the two populations is ten million, which is large. O C. The population of the species in 1970 is approximately 3160 million. This is not a close appoximation to the actual value of 3670 million, because the approximation does not take into account a massive growth increase between 1960 and 1970. b. The approximate population in 2000 is million. (Round to the nearest whole number as needed.) c. The approximate population in 2015 is million (Round to the nearest whole number as needed.)
