Urgent with 6 & 7 ! leave a explanation. : )

3,000,000

Step-by-step explanation:

#6) He gets 1.5 percent commission on total contracts and then an additional 2.5 percent on anything over 1.5 million.

Since his total contracts is 2,555,500,

He gets 1.5 percent of that, plus 2.5 percent of "2,555,500 - 1,500,000" which is 1,055,500

So his total pay is:

0.015*2,555,500 + 0.025*1,055,500 = $64,720

#7) Tobias earns $1,959 per month plus 6.3% commission on sales.  So let "s" be sales. His monthly earnings can be calculated by:

1,959 + 0.063s

In order for this amount to be $2,784.84, we need to solve:

1,959 + 0.063s = 2,784.84

Solve:

0.063s = 825.84

s = $13,108.57143

or $13,108.57

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
