Let U=(1,2,3,4,5,6,7,8) A={1,3,5,7} B={1,3,5,7} C={5,8} D={2,5,8}. What is the subset
nikitadnepr [17]
U={1,2,3,4,5,6,7,8}; A={1,3,5,7} = B; C={5,8}; D={2,5,8}
All are subset of U
A is a subset of B & vice versa
C is a subset of D, but neither C nor D are subset of A or B
5,120 because volume is area of base×height
Volume of a sphere = 4/3 pi r^3
A hemisphere is half a sphere so 1/2*4/3 pi r^3 = 2/3 pi r^3
Given diameter = 12.6 but we need radius so diameter /2 or 12.6/2 r=6.3
2/3*pi*6.3^3 =
2/3*pi*250.047
166.698*pi
= 523.7
Your answer is -71v+72 that is the answer
Answer:
- a. She needs to hang each triangle from its center of gravity or centroid, which is the point at which the three medians of the triangle intersect.
Step-by-step explanation:
- Medians meet at a centroid of the triangle. The centroid is the triangle's center of gravity.
