E = {1, 2, 3}

E ∩ F = {}

Step-by-step explanation:

Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,

Given

E = {1, 2, 3}

F = {101, 102, 103, 104}

We have to find the intersection of both sets as indicated

So,

E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}

E ∩ F = {}

As there are no common elements in both sets the intersection will be an empty set

9. Which of the following is the value of x in the solution to the

vladimir1956 [14]

Hi there,

9. Which of the following is the value of x in the solution to the

system of equations given below?

8 + 2x = 5y (1)

4x - y = 2 (2)

▪ (1)

y = ( 8 + 2x ) ÷ 5

▪ (2)

4x - [( 8 + 2x ) ÷ 5] = 2

( 20x - 8 - 2x ) ÷ 5 = 2

20x - 8 - 2x = 2 × 5

20x - 2x = ( 2 × 5 ) + 8

18x = 10 + 8

18x = 18

x = 18 ÷ 18

x = 1

The answer is : A. 1

Given cos theta=4sqrt2/7 find sin theta

m_a_m_a [10]

Answer:

$sin \theta=\sqrt{17}/7$

Step-by-step explanation:

<h3>Given</h3>

$cos \theta=4\sqrt{2}/7$

$sin \theta$

<h3>Solution</h3>

Use identity:

$sin^2x+cos^2x=1$

Substitute and find:

$cos^2 \theta=(4\sqrt{2}/7)^2$
$cos^2 \theta=16*2/49=32/49$

$sin \theta=\sqrt{1-cos^2 \theta} = \sqrt{1-32/49} =\sqrt{17/49} =\sqrt{17}/7$

The shape is composed of squares and quarter circles. Select all the expressions that represent its perimeter. (Select all that

Phantasy [73]

Answer:

91+14π

Step-by-step explanation:

The question is incomplete. Find the complete question attached.

From the diagram shown;

It contains 4 quarter circles which is equal to a circle.

Perimeter of a circle = 2πr

r is the radius = length of one side of the square =7

Perimeter of the circle = 2πr

Perimeter of the circle = 2π(7)

Perimeter of the 4 quarter circles = 14π

Also in the diagram, there are 13 sides of the square present.

Perimeter of the squares = 13×length of one side of the square (Sum of all the sides)

Perimeter of the squares = 13×7 =91

Perimeter of the figure = Perimeter of the 4 quarter circles + Perimeter of the squares

Perimeter of the figure = 91+14π
