The area of a new circle that has line segment GX as its diameter is 121 pi cm² .

Suppose that,

The radius of the small circle (GH) = 10 cm.

The radius of the big circle (HX) = 12 cm.

We will add the line GH and HX to get the total length of line segment GX.

So, GX = GH + HX

            = 10 + 12

      GX = 22 cm.

So, the diameter of new circle will be equal to line segment GX as it is given in the question.

Then, the area of new circle  = π r²    ( r = radius)

 Radius = D/2 = 22/2      (D = Diameter)

           r = 11

Now,     Area = π × 11²

                     = 121π cm²

Since their dot product is zero, then (6,-3) and (2,4) are normal to each other.

Step-by-step explanation:

Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.

These two vectors are also called orthogonal to each other.

Let u = (u₁, u₂) and  v = (v₁, v₂), then the dot product u . v is defined as:

u . v = u₁v₁ + u₂v₂

To check whether the vectors are normal to each other, let us check their dot product.

The given vectors are: (6,-3) and (2,4).

Let u = (6, -3) and  v = (2, 4), then,

u . v = 6 . 2 + (-3) . 4

        = 12 + (-12) = 0

Since u.v = 0, then (6,-3) and (2,4) are normal to each other.

The point after all the rotation and translation will become (17 - y, x + 12) from (x, y).

We need to first rotate the point 90° counterclockwise around the origin.

Let the point be (x, y)

When rotating a point 90° counterclockwise about the origin, the coordinate of the point (x, y) will become (-y, x). In other words, x and y will be switched and y will become negative.

Now, we need to translate the point 17 units right.

So, it means that the x - coordinate of the point will become x + 17

So, the point now becomes:

( -y , x ) = ( - y + 17 , x)

(17 - y, x)

Now we have to translate the point 12 units up.

So, we get that:

(17 - y, x + 12)

Therefore, the point after all the rotation and translation will become (17 - y, x + 12) from (x, y).

The three undefined terms that form the basis for geometry are:

- Point

- Line

- Plane

The term undefined is often used to refer to an expression that is not assigned an interpretation or a value.

The main three undefined terms of geometry are:

- Point

In geometry, a point has no dimension.

A point is represented by a dot.

The point has no length, width, or thickness.

A dot can be very tiny or very large.

- Line

A line is a straight one-dimensional figure that has a length but does not have a thickness, and it extends endlessly in both directions.

A line is made of a set of points that is extended in opposite directions infinitely.

- Plane

A plane, in geometry, prolongs infinitely in two dimensions.

It has zero thickness, zero curvature, infinite width, and infinite length.

It is also known as a two-dimensional surface.

Answer:

  138, 139

Step-by-step explanation:

You want the consecutive page numbers whose total is 277.

Consecutive integers differ by 1. If the lesser of two consecutive integers is represented by x, then the next one is (x+1). The sum of these two integers will be ...

  x + (x +1) = 2x +1

We want to find the numbers whose sum is 277:

  2x +1 = 277

  2x = 276

  x = 138

  x+1 = 139

The two page numbers are 138, 139.

__

Additional comment

It is customary for the odd page number to be on the right when the book is open. Fortunately, this problem makes that be the case.

Therefore, two page numbers are 138, 139 of a left and right page numbers of an open book are two consecutive integers whose sum is 277.

Positive numbers, negative numbers, and zero are examples of integers. 'Integer' is a Latin word that means 'complete' or 'completely'. This means that integers exclude fractions and decimals. In this article, we'll learn more about integers, their definition, and their properties.

All whole numbers & negative numbers are considered integers. This means that if we combine negative and whole numbers, we get a set of integers.

The difference between two consecutive integers is 1. The following integer is (x+1) if x is the lesser of two subsequent integers. These two integers' sum will be

x + (x +1) = 2x +1

So for 277 the equation will be

⇒  2x +1 = 277

⇒  2x = 276

⇒  x = 138

⇒  x+1 = 139

she needs to make 18 arrangements, so we divide 18 by 6 and get 3. 3 * 25 is 75 so the answer is 75.

Laura will arrange 18 flowers within 75 minutes of the time.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Laura can make six flower arrangements in 25 minutes if she makes 18 flower arrangements. The time will be calculated as,

The value of x in the angles is 14.

When parallel lines are cut by a transversal, angle relationships are formed.

The angle relationships that are formed includes corresponding angles, alternate angles, vertical angle etc.

Therefore, the value of x can be found as follows;

m∠1 = m∠7 (vertical angles)

Therefore,

m∠7 = m∠15(corresponding angles)

Hence,

m∠1 = m∠15

m∠1 = 8x - 4

m∠15 = 6x + 24

Therefore,

8x - 4 = 6x + 24

8x - 6x = 24 + 4

2x = 28

divide both sides by 2

x = 28 / 2

The value of the expression is 6.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

16 + 56 ÷ 2³ - 17

Applying PEMDAS.

= 16 + 56 ÷ 8 - 17

= 16 + 56/8 - 17

The inverse function returns the original value for which the output of a function was given.

The inverse of the function f(x) = (x - 4)² is f(x) = √x - 4

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Consider F(x) = y,

The x and y value is switched giving the necessary equation of

x = (y - 4)²

Then solve for y

√x = y - 4

simplifying the above equation, we get

y = √x - 4
