(a) Explanation Given: The given function is E ( t ) = 0.017 t 2 + 2.164 t + 8.061 , where t is the number of years after 1990 and E ( t ) is number of employees in thousands. The revenue in billion dollars is given by the function R ( E ) = 0.165 E − 0.226 , where E is the number of employees in thousands. Evaluate R ( E ( t ) ) as follows, R ( E ( t ) ) = R ( 0.017 t 2 + 2.164 t + 8.061 ) = 0 (b) To determine To find: The value R ( E ( 3 ) ) and to interpret the result. (c) To determine To find: The number of employees worked for Southwest airlines in the year 1997. (d) To determine To find: The revenue of airlines for the year 1997.
