In the plane, we have everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the plane, we have , which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the plane, , so
which is a circle centered at (0, -10, 3) of radius .
Answer:
160 off 20p coins
Step-by-step explanation:
- 1 p, 20 p, 5 p coins
- 1 p= 3/8 of the bag
- 5 p= 1 p= 3/8 of the bag
20 p coins= 640 - 640*(3/8+3/8)= 640*(1- 6/8)= 640 * 2/8= 640* 1/4= 160
One solution because the lines only cross once, at (0,3)
