Answer:
-83 1/3 > -83.518
Step-by-step explanation:
-8 1/3 = -8.333333...
360 /12 = 30
Each 5 minutes is 30 degrees
2*pi/12 = pi/6
each 5 minutes is pi/6 degrees
pi/3 = 2*pi/6 = 2 * pi/6 = 2* 5 minute = 10 minutes
the minute hand moves from 4 to 6
2 * pi/3 = 2 * (2*pi/6) = 4 *(pi/6) = 4 * 5 minutes = 20 minutes
The minute hand moves from 3 to 7
5 * pi/6 = 5 * 5 minutes = 25 minutes
the minute hand moves from 5 to 10
7 * pi/6 = 7 * 5 minutes = 35 minutes
the minute hand moves from 2 to 9
No, there can not be negative amplitude because it is just the distance between the max and the midline or the minimum and the midline.
I see where you might be confused because for instance in the trig equation:
y = -3 sin (.5(x-

/2)) -1, there is a negative in front of the amplitude. However, when finding the amplitude, you take the absolute value of a.
