Answer:

because the circle has equation: x² + y² = 8

=> the circle has the centre I(0;0)

the radius R = 2sqrt(2)

=> the area of the circle =

[tex](2 \sqrt{2})^{2} \times \pi = 8\pi =23.13 [/tex]

Answer:

(x, y) ⇒ (2x, 2y)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

Given that the inner circle has a radius of 1 r and the outer one has a radius of 2 r. To map the inner circle onto the outer circle, the inner circle would need to be enlarged. The scale factor is:

k = outer circle radius / inner circle radius = 2r / 1r = 2

A dilation with a scale factor of 2 would be needed to map the inner circle onto the outer circle.

That is:

(x, y) ⇒ (kx, ky)

The dilation should be (x, y) ⇒ (2x, 2y)

Transformation refers to the point movement that starts from beginning location to the new location. The dilation refers to the increment or decrement of the figure size.

Here,

The scale factor should be calculated by dividing the  outer circle radius from the inner circle radius

[tex]= 2r\div 1r[/tex]

= 2

Therefore, The dilation should be (x, y) ⇒ (2x, 2y)

Answer:

There are 6 cakes.

Each person can eat 1/2 of a cake.

You need to find how many times you can split 6 cakes into 1/2 of a cake.

Obviously, division is the way to go.

6 ÷ 1/2

When dividing by a fraction, you need to turn both parts into fractions.

6/1 ÷ 1/2

Now you skip the first part.

Focus on 1/2

Flip the fraction: 2/1

Now multiply the two fractions together

6/1 *2/1 = 12/1

Therefore 12 people can be at the party.

Answer: 12 people

Step-by-step explanation:

6 total cakes ; everyone eats [tex]\frac{1}{2}[/tex]

6 people would eat 3 cakes because [tex]\frac{1}{2}[/tex] × 6 people = 3 cakes.

However, 12 people would eat 6 cakes because [tex]\frac{1}{2}[/tex] × 12 people = 6 cakes.

Step-by-step explanation:

Answer:

x=56

Step-by-step explanation:

Alternate exterior angles are congruent if the lines crossed by the transversal are parallel (which they are).

Answer:

56

Step-by-step explanation:

It would also be 56 degrees because if both 360 degree angles are parallel to each other and if each of the 360 degree angles had two top and bottom 180 degree angles and if 56 was subtracted to 180 you would get 124 and when you plus that with 56, you get 180 so if that is true for all 4 180 degree angles in this problem, then X would equal 56 no doubt.

[tex] {2}^{3} \times {4}^{3} \times 9[/tex]

Step-by-step explanation:

Using the division rule when dealing with exponents

[tex] \frac{b {}^{h} }{b {}^{j} } = b {}^{h - j} [/tex]

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.

so using that we are going to do 2, 4 and 9

[tex] \frac{2 {}^{8} }{ {2}^{5} } = {2}^{8 - 5 = 3 \: \: \: \: \: 2 {}^{3} } [/tex]

[tex] \frac{ {4}^{4} }{ {4}^{1} } = {4}^{4 - 1} \: \: \: {4}^{3} [/tex]

[tex] \frac{9 {}^{9} }{ {9}^{8} } = {9}^{9 - 8} = 9 {}^{1} [/tex]

Combine all the terms and we get

[tex] {2}^{3} \times 4 {}^{3} \times {9}[/tex]

Answer:

B.

{(0, 0), (2, 8)}

Step-by-step explanation:

Substitute 4x in for y in the second equation.  

[tex]2x^{2} - 4x = 0\\[/tex]

2x(x - 2) = 0

x = 0    or x - 2 = 0

                     x = 2

Substitute x = 0 and x = 2  in the first equation to get the corresponding values for y

4(0) = y    and 4(2) = y

y = 0     or   y = 8

So, B is the correct answer

The measure of ∠O is, 115.8°.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

In ΔMNO, m = 150 inches, n = 550 inches and o=630 inches.

Now, We know that;

⇒ cos O = m² + n² - o² / 2mn

Substitute all the values, we get;

⇒ cos O = 150² + 550² - 630² / (2 × 150 × 550)

⇒ cos O = - 0.4357

⇒ ∠ O = 115.8°

Thus, The measure of ∠O = 115.8°

Answer:

x = 20

Step-by-step explanation:

4x + 5x = 9x

9x = 180 (supplementary angles add up to 180 degrees)

Divide 180/9 = 20

Answer:

x = 20.

Step-by-step explanation:

Supplementary angles sum to 180, so:

4x + 5x = 180
