Find the percent of change from 74 hours to 85 hours.

The answer would be 14.8645, but it'd be repeating, so it's actually 14.864864864864865.

I think you should write the entire number down just in case.

I'm so sorry. It would be a percent increase, so it's a positive.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
