For any integer n, all angles -150° n×360° will be coterminal with -150°. The appropriate choices are
-510° . . . . n=-1
210° . . . . n = 1
570° . . . . n = 2
Answer:
I don't know, I'm so sorry
To move from scientific notation to standard from move the decimal point the number of places of the exponent on the 10. In this case the exponent is -11, so you will need to move 11 places to the left. You will get:0.0000000000556 in standard form.
Answer:
She needs 78 inches of fabric.
Step-by-step explanation:
The rule for the amount of fabric that needs to be bought is:
![\text{fabric} = 2*x + 8](https://tex.z-dn.net/?f=%5Ctext%7Bfabric%7D%20%3D%202%2Ax%20%2B%208)
Where "x" is the distance from the waist to the finished length of the pants. Since Amy's is 35 inches, the amount of fabric is:
![\text{fabric} = 2*35 + 8\\\text{fabric} = 70 + 8\\\text{fabric} = 78 \text{ inches}](https://tex.z-dn.net/?f=%5Ctext%7Bfabric%7D%20%3D%202%2A35%20%2B%208%5C%5C%5Ctext%7Bfabric%7D%20%3D%2070%20%2B%208%5C%5C%5Ctext%7Bfabric%7D%20%3D%2078%20%5Ctext%7B%20inches%7D)
She needs 78 inches of fabric.
Use the slope formula:
m = (y2 - y1)/(x2 - x1)
Plug in the values into the equation:
m = (1 + 7)/(-7 - 5)
m = 8/(-12)
m = -(2/3)
The slope is -2/3
