Fred finishes one assignment in 3 hours. Assuming he works at a constant pace over several hours, write an equation that depicts the relationship between time in hours h and number of assignments finished f.

Let one assignment finished be f .

No. of hours he worked be h .

Assuming he works at a constant pace over several hours ,

Fred finishes assignment in 3 hrs = f

:. Fred finishes assignment in 1 hr =

:. Fred finishes assignment in h hrs =

HOPE IT HELPS

PLEASE MARK ME BRAINLIEST ☺️

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
