by seeing how far the distance is from the number line
No
Rf values can be used to identify the type of drugs that had been taken by those who went through drug overdose.
Absolute value can be used as distances, because if an object is either 1 foot behind or 1 foot in front of another object, their distance will still be 1.
The absolute value of something is also the square root of the square of that something. This can be used to solve equations involving absolute values.
Actually they are; but we often don't think of them that way, or call them that way. Quite often when talking about a "difference", the absolute value is implied - for instance, the "difference" between 5 and 7 is the same as the difference between 7 and 5.
Proportions are used in real life to determine prices of things.
Absolute poverty
The absolute value is used in the calculation of mean absolute deviation to eliminate negative differences. By taking the absolute value of each difference, it ensures that all values are positive, allowing for an accurate measure of the average deviation from the mean.
Believe it or not, school is a real life situation. If you are using it in school it real life for you.
Dont cheat. Cheating on that kmail will not get you anywhere. It is used by architects
If you are in school and are studying trig then you are using trig in real life.
The half-life of Carbon 14 and radionuclides are used to estimate the absolute (versus relative) age of pre-history items.
