x²+ y²+ 20x + 8y - 84 = 0 is equation of the circle .

What is a circle, exactly?

A circle is a closed, two-dimensional object in which all points in the plane are equally spaced apart from the center.

                    The symmetry line of reflection is formed by each line that traverses the circle. Additionally, it is rotationally symmetric about the center for all angles.

the equation of the circle with center (-10,-4) and a point on the required circle is (4,-2).

Clearly, radius of the circle will be distance between the center and the point on the circle.

    r = √( -10 - 4 )²+ ( -4 + 2 )²

     r =  √196 + 4

     r =  10√2

We know that circle with center at (h.k) and radius r has the equation

       ( x - h )² + ( y - k )² = r²

We have circle with radius 10√2    and center at (-10,-4) and its equation will be

        ( x+ 10 )² + ( y + 4)²= ( 10√2)²

     x²+ y²+ 20x + 8y - 84 = 0

Answer:

Diego's family cannot drive the car for 28 days without the warning light turning on.

Step-by-step explanation:

Since the car uses 0.6 gallons per day, and Diego's family has been driving the car for 28 days, that means the total amount of fuel used is [tex]0.6*28=16.8[/tex] gallons. To determine whether the warning light will be on or not, subtract the total amount of fuel - 18 gallons - by the amount of fuel already used. If the difference is greater than 1.5, that means the warning light will not come on. If the difference is less than or equal to 1.5, that means the warning light will come on. [tex]18 - 16.8 = 1.2[/tex], since 1.2 gallons is less than 1.5 gallons, that means Diego's family cannot drive the car for 28 days without the warning light turning on.

Answer:

no because the remaining fuel will be 1.2 gallon therefore the warning light will turn on

Step-by-step explanation:

18 gallon

0.6 per day

28 × 0.6 = 16.8

18 - 16.8 = 1.2

Answer:

Q= 114°

R= 37°

P= 29°

x= 37

Step-by-step explanation:

x + x-8 + 3x +3 = 180

5x -5 = 180

5x = 175

x= 37

R = x = 37°

p= x-8 = 37-8 = 29°

Q = 3x+3= 3×37+3 = 114°

Total time taken by Laurie to cover all kitchen walls = 15 hours

Step-by-step explanation:

Given:

Time taken by Laurie to cover 20% of kitchen walls = 3 hours

Find:

Total time taken by Laurie to cover all kitchen walls

Computation:

Total time taken by Laurie to cover all kitchen walls = Time taken for 20%[100%/20%]

Total time taken by Laurie to cover all kitchen walls = 3[10/2]

Total time taken by Laurie to cover all kitchen walls = 3[5]

Total time taken by Laurie to cover all kitchen walls = 15 hours

Answer:

75°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

let x be the sixth angle, then sum and equate to 720°

150 + 100 + 80 + 165 + 150 + x = 720

645 + x = 720 ( subtract 645 from both sides )

x = 75

The sixth interior angle is 75°

Answer:

The answer is $36

Step-by-step explanation:

Took the Star Math Test

Answer:

$36

Step-by-step explanation:

100% - 25% = 75%

75% as a decimal = 0.75

75% = 27

75% as a decimal = 3/4

So 3/4 x = 27

27 x 4 = 108

108 / 4 = 36

-Chetan K

Answer:

" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."

Step-by-step explanation:

Transformations can be written as operators that act on functions or shapes.

For example, we can define the horizontal translation operator as:

T(k)

And if we apply this to a function, we get:

T(k)[ f(x) ] = f(x - k)

Now, the operators are not necessarily commutative.

This means that if we have two operators:

K and L

is not the same:

K[ L[ f(x) ]]

than:

L[ K[ f(x) ]]

An example of this can be a reflection across the y-axis and a horizontal translation, that composition is non-commutative.

Now, let's go to our case.

A glide reflection is commutative, so we can perform the transformations in any order, then the statement is:

" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
