First you should plot the points and connect them so you can see the triangle.
Then you need to find the slope of each line segment. Then you need to get the slope that would be perpendicular to each individual slope.
Then you got to the OPPOSITE vertex of each line segment, and use the perpendicular slope from that vertex to draw a line, then you will see that all 3 of them intersect at (5,-1)
Hints:
cos(x) has a maximum at x=0.
It is also a periodic function with a period of 2pi.
Answer:
i would say 36
Step-by-step explanation:
because you take each line equally making a big square
2/3 of a number is greater than 66% of a number
5. Circuit city : 650 + 0.01(8000) = 650 + 80 = 730 per week
Best Buy : 250 + 0.06(8000) = 250 + 480 = 730 per week
6. Nasir should work at Circuit City. The reason I say this is the salary is 650 no matter what the sales are. And if he has a bad week in sales, he can always count on the salary. Best Buy is riskier because the majority of his pay is more dependent on his sales (which is not guaranteed)......whereas, Circuit City, the majority if his pay is in his salary (and that is guaranteed).
