What does positive and inverse mean, what is positive and inversely proportional

Proportional: two related quantities, one quantity changes, the other quantity also changes, if the ratio of the two corresponding numbers in these two quantities is constant, these two quantities are called proportional quantities, and their relationship is called proportional relationship.

Inverse Ratio: Two related variables, one quantity decreases as the other quantity increases or one quantity increases as the other decreases, and their product is the same, then the two quantities are inversely proportional.

proportional.

A is the value of b multiplied by a constant, then a is proportional to b.

It is not that A and B increase or decrease at the same time to be proportional. For example, a=kbk<0), b increases, and a decreases.

inversely proportional. A is proportional to the reciprocal of b (i.e., the reciprocal is multiplied by a constant), then a is inversely proportional to b.

If the relation between the physical quantity y and the physical quantity x can be written as:

y = kx, where k is quantitative, then y is proportional to x. (sometimes written as y x=k) y = k x, where k is quantitative, then y is inversely proportional to x. (sometimes written as xy=k).

Time is certain, distance and speed.

proportional. The speed is certain, the distance is the same as the time.

proportional. The distance is constant, time and speed.

inversely proportional. Work efficiency is certain, the total amount of work and time.

proportional. Time is certain, the total amount of work and work efficiency.

proportional. The total amount of work is certain, time and work efficiency.

inversely proportional. The pressure is constant, and the pressure is the area under force.

proportional. Density is constant, mass and volume.

proportional. The voltage is constant, the power and the current intensity.

proportional. The mass is constant, and the combined external force and acceleration are combined.

proportional. The mass is constant, the kinetic energy and the velocity are square.

proportional.

Proportionality refers to two related quantities, one quantity changes, and the other quantity also changes with it. If the ratio of the two corresponding numbers in these two quantities is constant, these two quantities are called proportional quantities, and their relationship is called proportional relations.

Inverse proportionality refers to two related variables, one quantity changes, and the other quantity also changes, if the product of the two corresponding numbers in these two quantities is constant, then they are called inversely proportional quantities, and their relationship is called inversely proportional relations.

Positive and inverse similarities.

1. There are two variables in the relationship between things, one quantitative.

2. In two variables, when one variable changes, the other variable also changes.

3. The product or quotient of the corresponding two variables is certain.

If the ratio of the two numbers corresponding to two dependent quantities is constant, these two quantities are called proportional quantities, and their relationship is called proportional relations.

If the letters x and y are used to represent the two related quantities, and k is used to represent their ratios, the proportional relationship can be expressed by the following formula: y x=k (certainly).

Inverse proportion. The concept of sexuality can be contrasted with direct proportionality. Considering two variables is considered to be "proportional to each other". If all other variables remain constant, if another variable increases, the amplitude or absolute value of an inversely proportional variable.

decreases, while its product (proportionality constant k) is always the same.

To put it simply, if one thing increases and another thing decreases, it decreases and another thing increases, and the relationship between the two things is called an inverse proportional relationship.

The meaning of proportion.

Positive correlation. When this positive value is 1, it is a perfect positive correlation, such as a pip arranged in a straight line, it is a perfect positive correlation. Although the meaning of positive correlation is clear, it is actually a vague concept that cannot be quantified, but only qualitative.

Proportional: Two related variables, one quantity changes, the other quantity also changes, if the ratio of these two corresponding values is constant, then the relationship between the two variables is called positive proportional relationship.

Function image. Peculiarity.

In terms of function graphs, the proportionality is a straight line, and there is a specific linear relationship;

A positive correlation is characterized by a trend that slopes upwards to the right and can be nonlinear.

Proportionality: two related quantities, one quantity changes, the other quantity also changes, if the ratio of the two numbers corresponding to these two quantities (that is, the quotient) is constant, these two quantities are called proportional quantities, their relationship is called proportional relationship, and the proportional image is a straight line.

Inverse proportionality: two related quantities, one quantity changes, and the other quantity also changes with the change, in the opposite direction. If the product of the two numbers corresponding to these two quantities is fixed, these two quantities are called inversely proportional quantities, and their relationship is called inversely proportional relations.

proportional. For example, if A is larger and B is also larger, then AB is proportional.

Inversely proportional: the larger A, the smaller B, and Ab is inversely proportional. The relationship between two quantities is proportional to each other, which means that "the quotient of these two quantities" is a fixed value, and the relationship between two quantities is inversely proportional means that "the product of these two quantities" is a fixed value.

If the ratio (i.e., quotient) of the two numbers corresponding to these two quantities is constant, these two quantities are called proportional quantities, and their relationship is called proportional relations, and we call these two variables proportional.

Inverse ratio: two things or two aspects of a thing, one side changes, and the other side changes oppositely, such as the elderly with age, physical strength gradually weakens, that is, inverse proportionality. The former term of a ratio is taken as the latter term, and the latter term is regarded as the former term, and the ratio constituted is inversely proportional to the original ratio.

For example, 9:3 and 3:9 are inversely proportional to each other.
