Freddie is at chess practice waiting on his opponent's next move. he notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.
part 1: how many radians does the minute hand move from 3: 35 to 3: 55? (hint: find the number of degrees per minute first.)
part 2: how far does the tip of the minute hand travel during that time?
you must show all of your work.

One complete revolution of the minute hand sweeps a central angle of 360° which is equivalent to 60 minutes.
That is, the minute hand creates
(360°/(60 min) = 6 degrees/min.

From 3:35 to 3:55 is 20 minutes.
It sweeps a central angle of
 (20 min)*(6 deg/min) = 120°

Because 360° = 2π radians,
120° = (120/360)*2π = (2π)/3 radians

 
In decimals, this is 2.1 radians (nearest tenth)

Part 2:
Because the minute hand is 4 inches long, the length of the arc swept is
(4 in)*(2π/3 radians) = 8π/3 inches

 
In decimals, this is 8.4 inches (nearest tenth).

  

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
