Circle 1 is centered at (5, 8) and has a radius of 8 centimeters. Circle 2 is centered at (1, −2) and has a radius of 4 centimet
Masja [62]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilation's) can be found that map one figure onto another.  

In this problem to prove circle 1 and circle 2 are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

we have that

Circle 1 is centered at (5,8) and has a radius of 8 centimeters

Circle 2 is centered at (1,-2) and has a radius of 4 centimeters

step 1

Move the center of the circle 1 onto the center of the circle 2

the transformation has the following rule

(x,y)--------> (x-4,y-10)

so

(5,8)------> (5-4,8-10)-----> (1,-2)

center circle 1 is now equal to center circle 2  

The circles are now concentric (they have the same center)

step 2

A dilation is needed to decrease the size of circle 1 to coincide with circle 2

scale factor=radius circle 2/radius circle 1-----> 4/8----> 0.5

radius circle 1 will be=8*scale factor-----> 8*0.5-----> 4 cm

radius circle 1 is now equal to radius circle 2  

therefore

A translation, followed by a dilation will map one circle onto the other, thus proving that the circles are similar

Write and solve an equation to find the values of d and w .
NNADVOKAT [17]

Answer:

d = 65°

w = 55°

Step-by-step explanation:

m∠DAC +∠m∠CAB = 60

m∠DAC + 35 = 60

m∠DAC = 25

m∠DAC + d = 90

25 + d = 90

d = 65°

m∠GAF + w + d = 180

60 + w + 65 = 180

w + 125 = 180

w = 55°

Which expression gives the distance between the points (2,5) and (-4, 8)?
german

Answer:

A. (2+4)² +(5-8)²

Step-by-step explanation:

To find then distance between two points, we will follow the steps below;

write down the formula

D = √(x₂-x₁)²+(y₂-y₁)²

(-4, 8)

x₁=-4

y₁ = 8

(2,5)

x₂=2

y₂=5

we can now proceed to insert the values into the formula

D = √(x₂-x₁)²+(y₂-y₁)²

   

   = √(2+4)²+(5-8)²

    =√(6)² + (-3)²

   =√36+9

   =√45

Therefore the expression which gives the distance between two the two points is  (2+4)² +(5-8)²

Inequalities part 2<br> I need help pls i dont understand
Bad White [126]

Step-by-step explanation:

For y/x to be as high as possible, y must have the highest possible value and x must have the lowest possible value. (12 and 6)

Hence, y/x < 12/6, which is 2.

For y/x to be as low as possible, y must have the lowest possible value and x must have the highest possible value (10 and 7)

Hence, y/x > 10/7.

Combining the 2 inequalities, we have 10/7 < y/x < 2.

What is the area of the square? Help me pls
Allushta [10]

Answer and Step-by-step explanation:

First, we need to find out the circumference of the circle.

We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.

2\pir

<u>Plug in 1 for r.</u>

2\pi (1) = 2\pi = circumference of circle

<u>Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.</u>

<u />2\pi x 4 = 8\pi = perimeter of square

<u>Now, divide the perimeter by 4 to get what the side of the square is.</u>

<u />8\pi ÷ 4 = 2\pi

<u>Now, multiply </u>2\pi<u> by </u>2\pi<u> (side times side) to get the area.</u>

2\pi x  2\pi = 4\pi

The answer is A. 4\pi
