The dilation is the one form of transformation, that will change the size of the original figure, but the shape of the figure remains same

Consider a triangle and dilating the triangle by a scale factor of 3

The scale factor 3 means the size of the original image will enlarge by three times of the original size .

The effort you put in while ascending the stairs is equal to the sum of the force you exerted (your weight) and the elevation you moved.

Which is: Work (in joules) is equal to your weight in newtons divided by the stairs' height in meters.

Your Body Weight It goes without saying that moving a heavy object up a flight of stairs takes more strength than moving a light object. However, you still need to push your body weight against gravity even if you don't carry anything. Therefore, the more weight you have, the more power you need to climb the stairs.

Student 1 would have a power of 467 W, while Student 2 would have a power of 433 W. The fourth option—student 1 would have a power of 467 W, while student 2 would have a power of 433 W—is the correct one.

Answer:

48 and 15/16

Step-by-step explanation:

49+1/8(-1/2)

49+(-1/16)

48 and 15/16

The required value of the expression is 3 when substituting the value of -1/2 for y.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The expression is given in the question as:

49 + 1/8y

To evaluate the expression, we need to substitute the value of -1/2 for y. Doing this gives us:

⇒ 49 + 1/8(-1/2)

⇒ 49 + (-1/16)

Simplifying the expression further gives us:

⇒ 49 - 1/16

⇒ (16 × 3 + 1 - 1)/16

⇒ 48/16

Apply the division operation, and we get

⇒ 3

Therefore, the final value of the expression is 3.

The values of x in the cyclic quadrilateral are 6.67 and 25 and the angle

m∠ ACB is 115°

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It is also sometimes called inscribed quadrilateral. The circle which consists of all the vertices of any polygon on its circumference is known as the circumcircle.

1)

Let's solve to find the value of x

Using proportions;

12/8 = 10 / x

x = 20 / 3

x = 6.67

2) To find x;

(4x + 15)° + (6x + 3)° + 92° = 360°

Sum of angles in a circle is 360°

4x + 15 + 6x + 3 + 92 = 360

10x + 110 = 360

10x = 250

x = 25

To find the value of m ∠ACB in the quadrilateral, we have to evaluate the value of x in the expression  = 4x + 15

m∠ ACB = 4(25) + 15

The triangle's vertices will therefore be A'(4, 6), B'(0, 0), and C'(-2,4) if it is mirrored across the y-axis and then dilated by a scale factor of 2.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.

Given

In line with the posed question.

Triangle ABC's vertices are A(-2, 3), B(0, 0), and C. (1, 2).

As we are aware,

The x-coordinates of each point must be negative while keeping the y-value constant in order to reflect a triangle over the y axis.

As a result, when triangle ABC is mirrored across the y-axis, its vertices are

A'(2,3)

B'(0, 0)

C'(-1, 2)

The vertices of the triangle will also change when it is dialated by a scale factor of 2.

The shortest length possible in the given question is 4.0×[tex]10^{-10}[/tex] cm .

Distance is measured by length. The quantity of length has the dimension of distance in the International System of Quantities. Most measurement systems choose a base unit for length from which all other units are derived. The metre serves as the fundamental unit of length in the International System of Units.

Most people interpret length to mean an object's longest dimension. Nevertheless, depending on the object's position, this is not always the case.

There are several terms for the length of a fixed object, including height, which is also known as vertical length or vertical extent, and width, breadth, or depth. When a base exists from which vertical measurements can be taken, height is used.

Nanometer(nm)- In the International System of Units (SI), a nanometer (American spelling) is a unit of length that is equal to 1000 picometres and one billionth (short scale) of a meter (0.000000001 m).

now , for find the shortest length we can covert all the given units into centimeter,

1 pm = [tex](10)^{-10}[/tex] cm

1 nm = [tex](10)^{-7}[/tex] cm

1 m =  100 cm

we have , 400 pm = 4× [tex](10)^{-8}[/tex] cm

                4.0 nm  =  4 × [tex](10)^{-7}[/tex] cm

      4.0 x [tex](10)^{-4}[/tex]m = 4 × [tex](10)^{-2}[/tex] cm

and   4.0 x [tex](10)^{-10}[/tex] cm

hence , clearly it is shown that shortest length is 4.0 x [tex](10)^{-10}[/tex] cm .

Two or more figures are said to be similar if and only if there are common properties of the sides and/or angles of the figures. The height of the tree is 8.85 meters.

Similar shapes have some common properties with respect to either their length of sides or measures of the internal angles. The relationship between similar sides can be expressed as a form of ration. But similarity of two or more shapes does not mean that the shapes are congruent.

In the given question, the construction gives similar triangles. Let the height of the tree be represented by h. Thus by similar properties of the sides of the triangles, we have;

[tex]\frac{1.65}{h}[/tex] = [tex]\frac{5.25}{28.15}[/tex]

h = [tex]\frac{1.65*28.15}{5.25}[/tex]

Let K(n) be the probability that Keiko gets n heads, and let E(n) be the probability that Ephriam gets n heads.

K(0) = 1/2

K(1) =1/2

K(2) = 0 (Keiko only has one penny!)

E(0) = 1/2 ×1/2 = 1/4

E(1) =  1/2 ×1/2 +  1/2 ×1/2 = 1/2  (because Ephraim can get HT or TH)

E(2) =  1/2 ×1/2 = 1/4

The probability that Keiko gets 0 heads and Ephriam gets 0 heads is K(0)×E(0). Similarly for 1 head and 2 heads.

The size of a matrix is ​​its dimension,

Matrix A has dimension 4 x 2 and matrix B has dimension 2 x 4

Matrix:

In mathematics, a matrix (multiple matrices) is a rectangular array or table of numbers, symbols, or formulas, arranged in rows and columns, used to represent mathematical objects or properties of such objects .

Product of Matrix:

Multiplication of two matrices is defined only if the number of columns in the left matrix equals the number of rows in the right matrix. If A is an m-by-n matrix and B is an n-by-p matrix, then its matrix product AB is an m-by-p matrix whose entries correspond to the corresponding rows of A in the matrices.

A column of B whenever a product of different sizes is such that it is defined.  The product AB can be defined without BA being defined. That is, if A and B are m-by-n and n-by-k matrices, respectively, and m ≠ k. In general, even if both products are defined, they need not be the same. So, AB ≠ BA,

Product AB:

The dimensions of AB are the rows of matrix A multiplied by the columns of matrix B.

Matrix A has 4 rows and Matrix B has 4 columns.

Therefore, the dimension of the matrix AB is 4 x 4.

Product BA:

The dimensions of matrix BA are the rows of matrix B multiplied by the columns of matrix A.

Matrix B has 2 rows and Matrix A has 2 columns.

Therefore the dimension of the matrix BA is 2 x 2.

Therefore, the sizes of AB and BA are 4 x 4 and 2 x 2 respectively.
