Answer:
Four unique planes
Step-by-step explanation:
Given that the points are non co-planar, triangular planes can be formed by the joining of three points
The points will therefore appear to be at the corners of a triangular pyramid or tetrahedron such that together the four points will form a three dimensional figure bounded by triangular planes
The number of triangular planes that can therefore be formed is given by the combination of four objects taking three at a time as follows;
₄C₃ = 4!/(3!×(4-3)! = 4
Which gives four possible unique planes.
The values for y are as follows
4.5, 4, 3.5, 3, 2.5, 2
Answer:
Step-by-step explanationtake the diameter, 10cm and multiply by pi (3.14) and the answer is 31.4
Answer:
3.33 or 3 1/3
Step-by-step explanation:
1/3 = 0.33
1 / 3 x 22 = 22 / 3
22/3 - 4 = 3.33 or 3 1/3
Answer:
= 10x-15-20z
Step-by-step explanation:
5 x 2=10 add the x to the end
5 x 3=15
5 x 4= 20 add the z to the end
Hope this helps (:
