select all the pairs that are alternate interior angles​

Answers

Answer:

- ∠3 & ∠5

- ∠2 & ∠8

----------------------------------------------------------------------

Interior Angles - Angles that appear INSIDE the transversal

Transversal - The shape you see with two parallel lines intersecting it.

Alternate - Opposite of each other, on the other side as well.

The alternate interior angles are the pair of ∠2,∠8 and ∠3,∠5.

What is alternating interior angle?

Alternate interior angles are the angles which are formed when two parallel lines cut by a transversal line.

Hence, the pair ∠2,∠8 and ∠3,∠5 are alternating interior angle.

I took the test

The circle radius increases , the circle moves down and the circle moves left.

What is circle?

A circle is special kind of "ellipse in which eccentricity is zero and the two foci are coincident".

According to the question,

The circle x² + (y-7)² = 49. When the given circle changes (x+5)² + (y-4)² = 64

Equation of the circle = (x-a)² + (y-b)² = r²

x² + (y-7)² = 49

(x-0)² + (y-7)² = (7)²

The circle has center (0,7) and radius is 7.

Circle changes (x+5)² + (y-4)² = 64

(x+5)² + (y-4)²  = (8)²

The circle has center (5,4) and the radius 8.

A: (13,−1)

B: 2

B: 2–√

Answers

Final answer:

The center of the given circle is at (13, 1), and the radius of the circle is 2.

Explanation:

The equation of a circle is generally given in the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius. Looking at the given equation (x - 13)^2 + (y - 1)^2 = 4, we can see that it is already in this standard form.

To answer the questions:

The center of the circle is (13, 1), which comes from the terms within the parentheses being subtracted from x and y.

The radius of the circle is not simply 4, as one might surmise by a quick glance. Instead, the equation gives us the radius squared, r^2 = 4. Taking the square root of both sides, we find that the radius, r, is 2.

And SHOW YOUR WORK PLEASE!!!!

Answers

Answer:

x = 2

y = -1

Step-by-step explanation:

Since it gives you the value of y already, just plug that into the equation, like so:

y = 4x - 9

x - 3 = 4x - 9

Subtract the x from both sides:

x - 3 = 4x - 9

-x       - x

__________

-3 = 3x - 9

Then, add 9 to both sides:

-3 = 3x - 9

+9        + 9

________

6 = 3x

Divide both sides by 3:

2 = x

Now plug in x for y:

y = x - 3

y = 2 - 3

y = -1

sin(B) = cos(90 -B)
cos(B) = sin(180 - B)
cos(B) = cos(A)

Answers

Answer: Choice 2)  sin(B) = cos(90-B)

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

Solving for A gets A = 90-B

So we end up with

sin(90-B) = cos(B)

A scale drawing of a square object has a scale of 1 in. : 5 mm. The scale drawing has a length of 2.5 inches. Find the perimeter and the area of the object in the scale drawing. Then find the perimeter and area of the actual object.

Answers

Answer:

Perimeter and area of drawing

Perimeter= 10 In

Area = 6.25 In²

Perimeter and area of object

Perimeter = 51.836 mm

Area = 167.936 mm²

Step-by-step explanation:

We are dealing with a square object, so let's talk about the drawing first.

The length of one side = 2.5 In

Perimeter of square= 4L

Perimeter = 4*2.5

Perimeter= 10 In

Area = L*L

Area = 2.5*2.5

Area = 6.25 In²

Letd note that 1 inch =

25.4 millimetres

So 2.5 Inch = 2.5 * 25.4

2.5 In = 63.5 mm.

25.4 mm is to 5mm

63.5 mm is to (63.5*5)/24.5

63.5mm is to 12.959 mm

So the length of actual object is 12.959mm

The perimeter = 4*12.959

Perimeter = 51.836 mm

Area = 12.959²

Area = 167.936 mm²

Answer:

The perimeter of the actual object  is 50 mm.

The area of the actual object is 156.25 mm square

Step-by-step explanation:

Given

Shape: Square

Scale: 1 in : 5 mm

Length of Scale Drawing = 2.5 in

Required:

- Perimeter of Actual Object

- Area of Actual Object

Calculating the perimeter of the actual object

Provided that the shape is a square;

The perimeter of the actual object is calculated by

Perimeter = 4 * Length

Recall that the scale is 1 in : 5 mm

This means 1 in on the scale represents 5 mm of the actual measurements of the object.

So, if 1 in ≈ 5 mm, then

2.5 in ≈ 2.5 * 5 mm

2.5 in = 12.5 mm

So, Length = 12.5mm

Now, the perimeter of the actual object can be calculated.

P = 4 * 12.5mm

P = 50mm

Hence, the perimeter of the actual measurements is 50 mm.

Calculating the area of the actual object

The area of the actual object is calculated by

Area = Length * Length

Recall that Length = 12.5 mm as calculated above

So,

Area = 12.5 * 12.5

Area = 156.25 mm square

Hence, the area of the actual object is 156.25 mm square

800 meters = 0.8 kilometers

And because kilometers are longer than meters.

Hoped this works!

7 kilometers  is longer than 800 meters.

What is Unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity

We need to find which  measurement is longer

7 kilometers or 800 meters

1 kilometer is equal to 1000 meters, so

7 kilometers is equal

7 kilometers = 7 x 1000 meters = 7000 meters

Since 7000 meters is greater than 800 meters, we can conclude that 7 kilometers is longer than 800 meters

Hence, 7 kilometers  is longer than 800 meters.

SA = 2(3*4 + 3*14+ 4*14)

     = 2(12+42+56)

    = 2(110)

    = 220

The calculated surface area of the net is 208 square units

Finding the surface area of the net

From the question, we have the following parameters that can be used in our computation:

The net of the prism

The surface area of the net is then calculated as

Surface area = Area of big rectangle + 2 * Area of small rectangle

So, we have

Surface area = (14 + 3 + 14) * 4 + 2 * 3 * 14

Evaluate

Surface area = 208

Hence, the surface area of the net is 208 square units

What is an equation?

An equation is an expression that is used to show the relationship between two or more variables and numbers.

Given that:

I(dB) = 10log(I/I₀)

Where I is the intensity of sound in w/m², I₀ = 10⁻¹²

Given that I = 10³², hence:

I(dB) = 10log(10³²/10⁻¹²) = 440 dB

Suppose a parabola has vertex (-8, -7) and also passes through the point (-7,-4). Write the equation of the parabola invertex form

Answers

Answer:

y = 3 (x+8)^2  -7

Step-by-step explanation:

The vertex form of the equation is

y = a(x-h)^2 +k

where (h,k) is the vertex

y = a (x- -8)^2 + -7

y = a (x+8)^2  -7

Now substitute the point into the equation to determine a

-4 = a (-7+8)^2  -7

-4 = a (1^2) -7

-4 = a -7

Add 7 to each side

-4+7 = a-7+7

3 =a

y = 3 (x+8)^2  -7

Answer:

y = 3(x + 8)² - 7

Step-by-step explanation:

y = a(x - -8)² - 7

y = a(x + 8)² - 7

-4 = a(-7 + 8)² - 7

3 = a

y = 3(x + 8)² - 7
