HELP ME PLS!!! -1 2/5 - ( -4/5)=?

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:

H is the Answer

Step-by-step explanation:

Apply distance formula.

[tex](x {}^{2 } - {x}^{1} ) {}^{2} + ( {y}^{2} - {y}^{1} ) {}^{2} = d {}^{2} [/tex]

where d is the distance.

[tex]( - 5 - 7) {}^{2} + (0 - 5) {}^{2} = [/tex]

[tex] - 12 {}^{2} + - 5 {}^{2} = {d}^{2} [/tex]

[tex] \sqrt{169} = {d}^{2} [/tex]

[tex]d = 13[/tex]

Answer:

H, 13

Step-by-step explanation:

Distance formula:

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\sqrt{(7-(-5))^2+(-5-0)^2}\\\sqrt{144+25}\\\sqrt{169}\\13[/tex]

Answer:

The scale used to draw the plan is 1: 200.

Step-by-step explanation:

Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:

12 m = 12 cm x 100 = 1200 cm

1200/6 = 200

Therefore, the scale used to draw the plan is 1: 200.

Answer:

Step-by-step explanation:

average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.

From the above question

Number of samples = 23 , less than 30,

Hence, we find confidence interval using t score

Confidence Interval using t score =

Mean + t score × standard deviation/√n

Step 1

We find the degree of freedom

= N - 1

= 23 - 1

= 22

Answer:

72°

Step-by-step explanation:

The interior angles of a triangle sum to 180°. Since there are two angles at 54°, we can use the equation x = 180 - 54 - 54 or x = 180 - 2(54), which will give us 72°.

Answer:

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:

D(4) = 6

Step-by-step explanation:

Using the blue graph, find the y value when x =4

the y value is 6 when x=4

D(4) = 6

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

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."

Answer:

A = Accrued amount (principal + interest)

P = Principal amount.

r = Annual nominal interest rate as a decimal.

R = Annual nominal interest rate as a percent.

r = R/100.

n = number of compounding periods per unit of time.

t = time in decimal years; e.g., 6 months is calculated as 0.5 years

Answer:

Step-by-step explanation:

Nah

To round each number to the nearest tenth, we have to look at the second digit after the decimal point, the hundredths. We look at tenths to round whole numbers, hundredths to round tenths, thousandths to round hundredths, etc. If the digit is 4 or below, then we would round down. If the digit is 5 or up, we would round up.

11.14

The digit is below 5, so we round down to 11.1.

9.543

The digit is also below 5, so we round down to 9.5.

Henceforth, adding these two numbers, we can conclude that an accurate estimation of the sum is 11.1 + 9.5, or 20.6.

If we wanted to round this answer further, we would use the same rounding rule. 20.6, where the tenths place digit, 6, is above 5, would be rounded up to 21.
