An observer is standing on the ground 16 meters from the point at which the balloon was released. Determine (in meters per minute) the rate at which the distance between the feet of the observer and the balloon is changing when the balloon is 12 meters high. ( Hint : remember 345 right triangles.) 1. rate = 18 meters/min 2. rate = 16 meters/min 3. rate = 19 meters/min 4. rate = 15 meters/min 5. rate = 17 meters/min 004 10.0 points Find f ′ ( x ) when f ( x ) = cos 2 x + 3 sin 2 x . 1. f ′ ( x ) = 8 sin x cos x 2. f ′ ( x ) = 4 sin x cos x 3. f ′ ( x ) = 4 sin x cos x 4. f ′ ( x ) = 8 sin x cos x 5. f ′ ( x ) = 2 sin x + 6 cos x 6. f ′ ( x ) = 2 sin x 6 cos x 7. f ′ ( x ) = 2 cos x + 6 sin x 005 10.0 points Find dy dx...
