Let Z={a,c,{a,b}}. What is |Z|?
Lina20 [59]

Z=\{a,c,\{a,b\}\}

\boxed{|Z|=3} (treat \{a,b\} as one element of Z)

The power set of Z is

\boxed{2^Z=\bigg\{\{\},\{a\},\{c\},\big\{\{a,b\}\big\},\{a,c\},\big\{a,\{a,b\}\big\},\big\{c,\{a,b\}\big\},\big\{a,c,\{a,b\}\big\}\bigg\}}

1. \{a,c\}\subseteq Z is true because both a\in Z and c\in Z.

2. a\in Z is true.

3. \{c\}\subseteq Z is true (same reason as part 1).

4. \{c\}\in Z is false because Z does not contain the set \{c\}, rather just the element c itself.

5. b\in Z is false because the element b on its own simply is not in Z. That b\in\{a,b\} does not mean b\in Z, but that b belongs to a subset of Z.

6. \{a,b\}\in Z is true.

To swap a figure to 90 degrees counter clock wise turn the points from

(x,y) to (-y,x)

Let’s get your points

(-2,3) ; (-4,2) ; (-2,-4)

Swap the values and make the new x’s negotiate

(-3,-2) ; (-2,-4) ; (4,-2)

These should be the points of the new figure with is 90 degrees counterclockwise of the first one.

10.

To find x you can either:

Add 93 and 54
Or
Find the missing value of the triangle and subtract it from 180. Let’s do both

x = 93 + 54
x = 147

Or

180 - 93 - 54
33
180 - 33 = 147

x = 147

8.

First we dilate the coordinates by 0.5

(-4,6) ; (2,6) ; (2,-4) ; (-4,-4)

Basically divide each x and by by two

(-2,3) ; (1,3) ; (1,-2) ; (-2,-2)

Two units left would be to subtract two from the x values

(-4,3) ; (-1,3) ; (-1,-2) ; (-4, -2)

Add three to each y value

New coordinates:

(-4,6) (-1,6) (-1,1) (-4,1)

6.

Since these are the same circle, then we need to multiply the radius by 2 and then make the newly formed diameters equal to each other

2(6x) = 10x + 8

Multiply

12x = 10x + 8

Get x on one side

2x = 8

Divide

x = 4

Plug in 4 for an equation

2(6(4))

48

Circumference = pi * diameter

Unsure if you use 3.14 for pi

If you use 3.14 :

(3.14) (48) = 150.72

If you use pi :

Pi (48) (rounded) = 150.80
