Social inequality in class 9 refers to the unequal distribution of social status, power, and privilege among individuals or groups within a society. It can manifest in various forms, such as discrimination, prejudice, and bias, which can limit opportunities and access to resources for certain groups.

In class 9, social inequality may be discussed in relation to various social issues, such as racial and ethnic inequality, gender inequality, and inequality based on sexual orientation, disability, and age. These issues can have a significant impact on individuals and groups, leading to reduced opportunities, access to resources, and lower quality of life.

Social inequality in class 9 may also be discussed in relation to broader societal issues, such as poverty, unemployment, and lack of access to healthcare and education. These issues can contribute to a cycle of disadvantage and can perpetuate social inequality.

It's worth noting that social inequality is often interconnected with other forms of inequality such as economic and educational inequality, and understanding how these inequalities interact is crucial to understand and address social inequality.

The range of pixel values in digital images is typically 0-255 because it corresponds to the number of bits used to represent each pixel. Most image file formats use 8 bits per color channel (red, green, and blue) to represent each pixel, and 8 bits can store a maximum of [tex]2^8[/tex] = 256 different values, with one of the values being reserved for transparency.

When working with 8-bit images, each color channel can take on one of 256 different values, from 0 to 255. This is known as an 8-bit color depth. Each pixel in the image is represented by a combination of red, green, and blue values, so the total number of possible colors is 256 x 256 x 256 = 16,777,216.

The use of 8-bit color depth allows for a wide range of colors to be represented in an image, while also being small enough to be easily stored and transmitted.

Also, it's worth mentioning that with the development of technology, the use of high-bit color-depth images has become more common in the field of photography, digital art, and video, where 16-bit and 32-bit color depths are frequently used.

An image is a representation of something that can be seen, such as a picture or drawing.

An image can be thought of as a 2-dimensional array of pixels, where each pixel has a specific color value. Each color value can be represented by numerical values, such as red, green, and blue (RGB) values.

In mathematics, we can think of an image as a function that maps the x and y coordinates of a pixel to its color value. For example, f(x,y) = (R, G, B) where R, G, B are the red, green, and blue values of that pixel.

We can also think of an image as a grid of points, where each point represents a pixel.

It can be a photograph, drawing, graphic, or any other visual representation of something. Images can be created using different techniques, such as painting, drawing, or photography.

They can also be digital, such as a computer-generated image or a photograph that has been scanned into a computer. Images are used in many different fields, such as art, science, advertising, and education.

Images can be found in various forms such as on billboards, posters, books, magazines, newspapers, websites, and social media platforms. They can also be used to communicate information, tell a story, or express an idea.

Answer: $270

Step-by-step explanation:

you multiply 10.00×9= 90 and then 15.00×10=150 then i took the answer out of both problems and added them. 150+90=240 then i took 240 + 30 = 270

The values of x are [tex]\frac{\sqrt{31} + 2 }{3} , \frac{-\sqrt{31} + 2 }{3}[/tex] and y are [tex]\frac{19\sqrt{31} + 146 }{9} , \frac{-19\sqrt{31} + 146 }{9}[/tex].

Given Equations,

4x² + x - y = 0 ...(1)

-x² - 5x + y - 9 = 0

The above equation can be written as:

-x² - 5x + y = 9 ...(2)

Using the elimination method, the second term of both equations can be eliminated by adding the equations.

Therefore,

4x² +  x  - y = 0

-x² - 5x + y = 9

_____________

3x² - 4x = 9

Using the Completing the square method,

3x² - 4x = 9

Divide the equation by 3 on both sides,

[tex]x^{2} - \frac{4}{3}x = 3[/tex]

[tex]x^{2} - \frac{4}{3}x + (\frac{2}{3}) ^{2} = 3 + (\frac{2}{3}) ^{2[/tex]

[tex]( x - \frac{2}{3})^{2} = 3 + \frac{4}{9}[/tex]

[tex]( x - \frac{2}{3})^{2} = \frac{31}{9}[/tex]

[tex]( x - \frac{2}{3}) = \sqrt{\frac{31}{9}}[/tex]

[tex]x = \frac{\sqrt{31} }{3} + \frac{2}{3} , - \frac{\sqrt{31} }{3} + \frac{2}{3}[/tex]

[tex]x = \frac{\sqrt{31} + 2 }{3} , \frac{-\sqrt{31} + 2 }{3}[/tex]

Now, Put the value of x  in equation (1), we get the value of y.

4x² + x - y = 0

y = 4x² + x

[tex]y = 4( \frac{\sqrt{31} + 2 }{3})^{2} + \frac{\sqrt{31} + 2 }{3} , 4( \frac{-\sqrt{31} + 2 }{3})^{2} + \frac{-\sqrt{31} + 2 }{3}[/tex]

[tex]y = \frac{19\sqrt{31} + 146 }{9} , \frac{-19\sqrt{31} + 146 }{9}[/tex]

Therefore,

the values of x are [tex]\frac{\sqrt{31} + 2 }{3} , \frac{-\sqrt{31} + 2 }{3}[/tex] and y are [tex]\frac{19\sqrt{31} + 146 }{9} , \frac{-19\sqrt{31} + 146 }{9}[/tex].

A statement which correctly describes the graph shown below is: A. The object moves away from the origin at a speed of 3 m/s, stands still 6 m away from the origin for 3 seconds, then moves toward the origin at a speed of 2 m/s.

In Mathematics, a position vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled by an object from its starting position with respect to the time when it is started moving.

Generally speaking, the position or distance traveled by a physical object in a position vs time graph is always plotted on the y-coordinate while time is always plotted on the x-coordinate (x-axis).

In this scenario, the speed of the object from the origin can be calculated as follows:

Speed = distance/time

The Pythagorean Theorem is a mathematical formula used to find the length of the missing side of a right triangle. It states that the sum of the squares of the lengths of the two shorter sides (known as the legs) of the triangle is equal to the square of the length of the longest side (the hypotenuse).

The area of a space refers to the amount of two-dimensional space that it occupies. For example, the area of a rectangle can be found by multiplying its length by its width.

The perimeter is the distance around the outside of a shape, often used in polygons and closed figures.

A Pythagorean triple is a set of three integers a, b, and c that satisfy the equation a^2 + b^2 = c^2. These integers correspond to the three sides of a right triangle, with c being the hypotenuse.

The hypotenuse is the side of a right triangle that is opposite from the right angle and is also the longest side of a right triangle.

The Pythagorean Theorem Converse states that if the sum of the squares of the two shorter sides of a triangle is equal to the square of the length of the longest side, then the triangle is a right triangle.

The Pythagorean Theorem can be used to find the diagonal distance on a coordinate plane. Given the coordinates of two points, the theorem can be used to calculate the distance between them by making the diagonal distance the hypotenuse.

The legs of a right triangle are the two sides of the triangle that are adjacent (next to) to the right angle.
