Answer with Step-by-step explanation:
We are given that A, B and C are subsets of universal set U.
We have to prove that
Proof:
Let x
Then and
When then but
Therefore, but
Hence, it is true.
Conversely , Let but
Then and
When then
Therefor,
Hence, the statement is true.
Answer: 7π
Step-by-step explanation:
7 * n since it says in terms of pie, you do not have to multiply just leave pie alone.
You have to add a 1 underneath it so it's reciprocal is 1
Answer:
Y Intercept: 10 Slope=2 y=2x+1
Step-by-step explanation:
Y intercept is when the line touches the y axis, which in this case is 10.
Rise over run: 2/1 (2)
y=mx+b (point slope formula)
For this case we have that by definition, the area of a rectangle is given by:
Where:
a, b: They are the dimensions of the rectangle.
In the statement we are told that "The area is greater than 12 square inches", then:
Also we have:
Substituting we have:
Dividing between 2 on both sides:
Finally we have:
