How to solve day to day problems using quadratic equation

Quadratic equations can be used to solve various day-to-day problems, such as:

1. _Projectile motion_: Trajectory of a thrown object, like a ball or a projectile, can be modeled using quadratic equations.

2. _Optimization problems_: Find the maximum or minimum value of a quadratic function, like maximizing area or minimizing cost.

3. _Physics and engineering_: Describe the motion of objects, like springs, pendulums, or electric circuits, using quadratic equations.

4. _Economics_: Model supply and demand curves, revenue, and profit functions using quadratic equations.

5. _Computer graphics_: Create smooth curves and surfaces for visual effects, video games, or design.

6. _Surveying and navigation_: Calculate distances, heights, and angles using quadratic equations.

7. _Electrical circuits_: Analyze and design circuits with resistors, capacitors, and inductors.

8. _Mechanical systems_: Model vibrations, oscillations, and rotations in mechanical systems.

9. _Data analysis_: Fit quadratic curves to data for trend analysis and forecasting.

10. _Architecture_: Design arches, domes, and other curved structures using quadratic equations.

To solve day-to-day problems using quadratic equations:

1. Identify the problem and variables.
2. Translate the problem into a quadratic equation.
3. Solve the equation using factoring, quadratic formula, or graphing.
4. Interpret the solutions in the context of the problem.

Example: A ball is thrown upwards with a velocity of 20 m/s. The height (h) of the ball at time (t) seconds is given by the quadratic equation: h = -5t^2 + 20t + 1. Find the maximum height reached by the ball.

Solution: Use the quadratic formula or graphing to find the vertex of the parabola, which represents the maximum height.

Repentance of one who committed Oral Sex

Praise be to Allaah. There is no doubt that what you have done is a kind of zinaa (unlawful sexual activity), although it is not the worst kind, so you must repent sincerely to Allaah, give up this sin, regret what has happened and be determined never to go back to it. Avoid bad friends and bad places, lower your gaze and keep your distance from women to whom you are not related (non-mahram). If you repent to Allaah, He will accept your repentance. You are still a Muslim, but you have committed an act of disobedience towards Allaah by doing this sinful act, so come back to your Lord and seek His forgiveness for what you have done. Do more good deeds to expiate for and cancel out your bad deeds, do those things that will help you to remain chaste, and hasten to marry according to Islam. Finally, we will leave you with a story from which you may learn a valuable lesson: Ibn Mas’ood reported that a man came to the Prophet (peace and blessings of Allaah be upon him) and told him that h...
