the expansion is strain e times length L or y = eL
if strain is temperature related then e = CTE x temperature T where CTE is linear thermal expansion coefficient or y = CTE x L x T

What is the relationship between linear and cubic expansivity?
Linear expansivity is the increase in length per unit length per degree rise in temperature. While cubic expansivity is the increase in volume per unit in volume per degree rise in temperature.
What the formula for area expansivity?
2*linear expansitivity
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
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).
How does finding slope compare to finding the rate of change between two variables in a linear relationship?
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
What is the relationship between linear and cubic expansivity?
Linear expansivity is the increase in length per unit length per degree rise in temperature. While cubic expansivity is the increase in volume per unit in volume per degree rise in temperature.
What is coefficient of cubical expansivity?
The coefficient of cubical expansivity would normally be the cube of the coefficient of linear expansivity unless that coefficient is different in different directions for a material. In that case it would be the product of the linear coefficients in the different directions.
What the formula for area expansivity?
2*linear expansitivity
What mathematical relationship between variables is suggested by a graph showing a half-parabola?
inverse linear or quadratic
What is the term linear expansivity?
It is defined as close in temperature of substance
What mathematical relationship between variables is suggested by a graph showing a diagonal line from the lower left to the upper right of the graph?

What mathematical relationship between variables is suggested by a graph showing a diagonal line from the lower left to the upper right the graph?
Linear
Why was there a need to invent linear equation in two variables?
If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one.

What is meant by mathematical model in particular linear programming model?
A mathematical model is the representation of a relationship or state or phenomenon in a mathematical form using control variables.
Is the relationship between inches and centimeters linear or non linear?
It is linear.
What is linear programming used for?
Linear Programming is used for determining a way to find the best solution or outcome for a given mathematical model represented as a linear relationship.
What is similar between an inverse relationship and a linear relationship What is different?
