Answer:
Option (B).
Step-by-step explanation:
Option (A).
A, F and B are lying on a line on the plane M.
True.
Option (B).
CD lies on the plane M, but its not clear that angle between the plane M and P is 90°.
False.
Option (C).
A, B and C are coplanar.
Since, these three points lie on the plane M, they are coplanar.
True.
Option (D).
Plane M intersects plane P in FH.
Since, line of intersection of the two planes M and P will be FH.
True.
Therefore, Option (B) will be the correct option.
Answer:
The slope is 1 I believe.
B, Only(-3,3)
-3(-4)-4=6
8=6
This ordered pair does not work, as 8 does not equal 6.
-3(-3)-3=6
6=6
This ordered pair works!
Answer: 1.2704 ohm
Step-by-step explanation:
Since resistance is directly proportional to the length of the conductor.
Let x be the resistance of the same conductor at 800 feet.
Then by direct proportion,
![\frac{x}{800}=\frac{0.397}{250}\\\Rightarrow\ x=\frac{0.397\times800}{250}\\\Rightarrow\ x=1.2704](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B800%7D%3D%5Cfrac%7B0.397%7D%7B250%7D%5C%5C%5CRightarrow%5C%20x%3D%5Cfrac%7B0.397%5Ctimes800%7D%7B250%7D%5C%5C%5CRightarrow%5C%20x%3D1.2704)
hence, the resistance of same conductor at 800 feet = 1.2704 ohm
3/8-12/8= -9/8, 9/16-12/16= -3/16, -18/16--3/16= --21/16 I think this is correct
