Which function describes the graph shown below? y=1/2sin(x)-2
y=2sin(x)-1/2
y=1/2cos(x)-2
y=2cos(x)-1/2

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer

i dont know

5/12

step-by-step explanation:

give them both a common denominator so you get 9/12 and 4/12. subtract 9/12 from 4/12 to get 5/12.
