)The number of elements in power set {1, 2, 3} is (a) 4 (b) 6 (c) 8 (d) 9
1 answer:
Answer:
<h2>(c) 8</h2>Step-by-step explanation:
The number of elements in a power set = the number of subsets of a set
Formula:
Let S be a sent ,the number of elements of the power set of S =
Where card(S) = number of element of S itself.
=======================================
In this case :
Card(S) = 3
Then
the number of elements of the power set of S =

Answer:
The equations represent circles that result in the same graph.
Step-by-step explanation:
we have
Divide by -10 both sides
-----> equation A
This is the equation of a circle centered at origin with radius
and
Divide by 5 both sides
-----> equation B
This is the equation of a circle centered at origin with radius
equation A and equation B are equal
therefore
The system has infinite solutions, because the equations represent circles that result in the same graph.
