Quadratic equations are used in various everyday situations, such as determining the trajectory of projectiles in sports and engineering, optimizing areas in construction, and calculating profits in business. For instance, when designing a garden or a field, quadratic equations can help find the maximum area that can be enclosed with a given perimeter. Additionally, they can model situations involving area and volume, such as in packaging design. Overall, their applications help in making informed decisions in both personal and professional contexts.
A real-life example of linear equations can be found in budgeting. For instance, if you earn a fixed salary of $3,000 per month and have fixed expenses like rent ($1,200) and utilities ($300), you can represent your savings as a linear equation: S = 3000 - (1200 + 300) - x, where S is your savings and x represents any additional expenses. This equation allows you to see how changes in your spending impact your savings over time.
There are many real life situations in which two variables are related through a linear equation. Some examples from those used in schools: Temperature in Celsius and Fahrenheit scales Manufactrunig costs as fixed costs plus unit costs Cab fares as fixed amount plus distance-related amount Workmen charges as call out plus hourly rate
Linear functions are used to model situations that show a constant rate of change between 2 variables. For example, the relation between feet and inches is always 12 inches/foot. so a linear function.What_is_a_real_life_example_of_bay
There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.

Determunants simplified the rule for solving simultaneous linear equations.
Pros: There are many real life situations in which the relationship between two variables is quadratic rather than linear. So to solve these situations quadratic equations are necessary. There is a simple equation to solve any quadratic equation. Cons: Pupils who are still studying basic mathematics will not be told how to solve quadratic equations in some circumstances - when the solutions lie in the Complex field.

Linear algebra is used to analyze systems of linear equations. Oftentimes, these systems of linear equations are very large, making up many, many equations and are many dimensions large. While students should never have to expect with anything larger than 5 dimensions (R5 space), in real life, you might be dealing with problems which have 20 dimensions to them (such as in economics, where there are many variables). Linear algebra answers many questions. Some of these questions are: How many free variables do I have in a system of equations? What are the solutions to a system of equations? If there are an infinite number of solutions, how many dimensions do the solutions span? What is the kernel space or null space of a system of equations (under what conditions can a non-trivial solution to the system be zero?) Linear algebra is also immensely valuable when continuing into more advanced math topics, as you reuse many of the basic principals, such as subspaces, basis, eigenvalues and not to mention a greatly increased ability to understand a system of equations.

it help us in this life because we can be able to use signs and alphabet to represent data
earthquake magnitude is exponential, not linear. for every increase of 1 on the Richter scale, an earthquake releases 10 times as much energy. The Richter scale has been superseded the moment magnitude scale (MMS). MMS is still logarithmic, but deviates somewhat from the Richter scale (an increase of one indicates about 30 times as much energy). Certain equations or algorithms might be designed for a linear scale, but for most applications a linear scale would be unnecessary and impractical. == == == ==

If you are a scientist, engineer or mathematician, there are too many examples to list. If you aren't, then there are basically none, except in finance.
