Express the radius r of this circle as a func- tion of the time t and then determine A r, where A is the area of the ripple. 1. ( A r )( t ) = 25 2 t 2 2. ( A r )( t ) = 5 t 2 3. ( A r )( t ) = 25 t 2 4. ( A r )( t ) = 5 2 t 2 5. ( A r )( t ) = 5 t 002 10.0 points Use the table x 1 2 3 4 5 6 f ( x ) 4 3 6 2 6 1 g ( x ) 3 2 4 2 6 4 to evaluate each expression: ( a ) f ( g (1)) ( b ) g ( f (1)) ( c ) f ( f (1)) ( d ) g ( g (1)) ( e ) ( g f )(3) ( f ) ( f g )(6) 1.
