Evaluate:

Use j = -9 and k = 4

so the way that you would have to solve this is to first do -9*4 which is -36 so then you subtract that from 4 which gives you your answer of:

-40

Hope this helps bye!

Step-by-step explanation:

Hey there!

4 - jk

= 4 - (-9)(4)

= 4 - (-36)

= 4 + 36

= 40

40

Good luck on your assignment and enjoy your day!

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
