Throughout this, I'm assuming that the scale is: 1 square = 1
Not 100% sure if my answers are correct.
Question 1:
The x coordinate must be 2 and the y coordinate must be -1.
Question 2:
The x coordinate would be -2 and the y coordinate would be -1.
Answer:
9² = 40² + 41² - 2(40)(41) cos(C)
81 = 1600 + 1681 - 3280 cos(C)
81 = 3281 - 3280 cos(C)
-3200 = -3280 cos(C)
cos(C) = 3200 / 3280
cos(C) = 40 / 41
Step-by-step explanation:
Quadrant number 3

-2.65
That is how you subtract 25 from 2.65
Hello!
As you can see, C is the cost of each uniform. This would give us the equation below, if each uniform was $60.
60=40n+260/n
Let's multiply both sides by n.
60n=40n+260
Now, let's subtract 40n from both sides.
20n=260
We divide both sides by 20.
n=13
Therefore, 13 uniforms were purchased.
I hope this helps!
