What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
What is the relationship between two quantities in which one quantity depends on the other?
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
What is a math expression example?
A math expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities.
Is direct variation a function?
A direct variation is a situation in which two quantities -- such as hours and pay, or distance and time -- increase or decrease at the same rate. The ratio between the quantities is constant; that is, as one quantity doubles, the other quantity also doubles. so yes it is. -add on- A direct variation is in the form y=ax where a is an constant.
Who would use a graph or where?
To visually see the relationship between quantities such that one of them can vary independently and the other varies by some amount (or factor) dependent on the independent quantity.
What is the relationship between two quantities in which the ratio of one quantity to the other quantity is constant?
A linear relationship
What is a relationship between two quantities in which the ratio of one quantity to other quantity is constant?
It is called direct variation.
What is a relationship between two quantities in which the ratio of one quantity to the other is constant?
It is called direct variation.
When a rate of change varies from point to point the relationship is what?
it is a proportional relationship because a proportional relationship is known as a relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
The relationship between two quantities that increase or decrease together is called what?
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
4 kinds of relationships between the physical quantities?
Direct relationship: When two quantities increase or decrease together. Inverse relationship: When one quantity increases while the other decreases. Linear relationship: When the relationship between the quantities can be represented by a straight line. Nonlinear relationship: When the relationship between the quantities cannot be represented by a straight line.
What is the relationship between two variables quantities with a constant ratio?
It is a direct proportion.
What has a variation in the relationship between two variable quantities with a constant ratio?
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
What is the simplified proportional relationship called?
A proportional relationship between two quantities is one in which the two quantities called the unit rate, the rate of change, or the constant of proportionality.
What is the relationship between two quantities in which one quantity depends on the other?
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
How do you calculate the constant of proportionality?
The constant of proportionality can be calculated by dividing the output variable by the input variable in a proportional relationship. It represents the ratio between the input and output quantities in the relationship. This constant remains the same throughout the relationship.
