P(A) is the power set of A. Show that-
(i) P(AUB) = P(A) ∩ P(B) is always true, but
(ii) P(AUB) = P(A) U P(B) may not be always true.
[tex]\large\underline{\sf{Solution-}}[/tex]
Let assume that,
[tex]\rm \longmapsto\:A \: = \:\{x\} \: [/tex]
and
[tex]\rm \longmapsto\:B \: = \:\{y\} \: [/tex]
[tex]\rm\implies \:A \: \cap \: B = \phi [/tex]
and
[tex]\rm \longmapsto\:A\cup B = \{x, \: y\}[/tex]
We know,
Power set of a set A is defined as set of subsets of A.
So,
[tex]\rm \longmapsto\:P(A) = \{ \phi ,\: x\}[/tex]
and
[tex]\rm \longmapsto\:P(B) = \{ \phi ,\: y\}[/tex]
and
[tex]\rm\implies \:P(A \: \cap \: B) =\{ \phi \}[/tex]
and
[tex]\rm \longmapsto\:P(A\cup B) = \{\phi ,x,y,xy\}[/tex]
Now, Consider
[tex]\rm \longmapsto\:P(A)\cup P(B) = \{\phi ,x,y\}[/tex]
and
[tex]\rm \longmapsto\:P(A\cup B) = \{\phi ,x,y,xy\}[/tex]
[tex]\rm\implies \:\boxed{\tt{ \: P(A)\cup P(B) \: \ne \: P(A\cup B) \: }} \\ [/tex]
Now, Consider
[tex]\rm \longmapsto\:P(A\cap B) = \{\phi \}[/tex]
and
[tex]\rm \longmapsto\:P(A) \: \cap \: P( B) = \{\phi \}[/tex]
[tex]\rm\implies \:\boxed{\tt{ \: P(A)\cap P(B) \: = \: P(A\cap B) \: }} \\ [/tex]

Triangle ABC has angle measures as shown show work.complete sentence
a. What is the value of x?
b. What is the measure of angle CAB?
d. When these 3 interior angles of a triangle are added together, what does it equal?
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees.
a.
90 + 2x + (3x - 20) = 180
90 + 2x + 3x - 20 = 180
70 + 5x = 180
5x = 110
x = 22
b.
2(22) = 44
c.
The interior angles of a triangle add up to 180 degrees.

what is an equation of the line that passes through the point (-8,0) and is parallel to the line x+2y=14
The quantities x and y are proportional. Find the constant of proportionality (r) in the equation y=rx
Answer:
y=rx 1/4/5/5/5
Step-by-step explanation:
Answer:
r = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The proportional equation is
y = rx ( divide both sides by x )
[tex]\frac{y}{x}[/tex] = r
Substitute any ordered pair from the table
Using (14, 7 ) , then
r = [tex]\frac{7}{14}[/tex] = [tex]\frac{1}{2}[/tex]
Write an equation. A number is doubled, then 9 is added. The result is 23.
Answer:
2n + 9 = 23
Step-by-step explanation:
let the number be n then double the number is 2n and adding 9 gives
2n + 9 ( the result is 23 ) , so
2n + 9 = 23 ← is the equation modelling the statement

Answer:
x = 14
Step-by-step explanation:
10x-30+5x = 180
Combine like terms
* 15x-30 = 180
Add 30 from both sides
* 15x 30+-30 = 180+30
Divide 15 both sides
* 15x/15x = 210/15x
x = 14

Solve 5x + 2 = 22
Solve 2x-5=7
Solve 2x+5=12
Answer:
x = 4
x = 6
x = 7/2
Step-by-step explanation:
Solve 5x + 2 = 22:
5x+2-2=22-2 (subtract 2 from both sides)
5x=20
x=4
Solve 2x-5=7
2x-5+5=7+5 (add 5 to both sides)
2x=12
x=6
Solve 2x+5=12
2x+5-5=12-5 (subtract 5 from both sides)
2x=7
x= 7/2
=> 5x + 2 = 22
=> 5x = 22 – 2
=> 5x = 20
=> x = 20/5
=> x = 4
Solve 2x-5=7=> 2x - 5 = 7
=> 2x = 7+5
=> 2x = 12
=> x = 12/2
=> x = 6
Solve 2x+5=12=> 2x + 5 = 12
=> 2x = 12-5
=> 2x = 7
=> x = 7/2

The p/q form of 0.4277777....... ,9 # 0 is 77/180 ( ) 180 43 90 37 90
Answer:
77/180
Step-by-step explanation:
x = 0.42777....
Multiply by 1000 (the number of digits in decimal)
1000x = 427.7777......
100x = 42.7777...... {Now subtract}
900x = 385
x = 385/900
x = 77/180

= (-2-1)²
= (-3)²
g(-2) = 9
g(0) = (x -1)² ; -2 ≤ x < 1
= (0 -1)²
= (-1)²
= 1
