Question

What are the three things that helps you in representing real-life situation to rational function?

Answer 1

Answer:

Equations representing direct, inverse, and joint variation are examples of rational formulas that can model many real-life situations. As you will see, if you can find a formula, you can usually make sense of a situation.

Answer 2

The three things that help you in representing real-life situations to rational function are known as:-

• Direct variation- Direct equation can be directly applied to any given situation.
• Inverse Variation- Inverse variation is represented by the equation xy=k or y=kx, in which when one variable increases the other variable decreases. Therefore, one variable has an inverse effect on the other variable.

• Joint Variation- Joint variable is X = KYZ in which the variable K is always constant.

• These equations are examples of rational formulas is used in every situation and applied in all cases to find out the solution of the problems.
• The algebraic formula is generally written as W = r t, where W= work done, r=rate of work, t=time taken.
• Rational formulas are very useful to find out solutions to such problems.
