What is the role of Chapter Polynomials of class 9th in our daily life?

Answer 1

Answer:

hey mate

here is ur answer

A2A. The most commonly used polynomial equation is a line. It is used all the time, as I'm sure you know.

So let's go on to quadratic polynomials. These are in the form y=ax2+bx+c , where a, b, and c are real constants.

You'll be surprised by the number of applications that use quadratic equations.

Throw a ball in the air. The arc it follows is a parabola. And a parabola can be represented by a quadratic equation.

Here's an upside down parabola. Ignore the parts below the x-axis. If you were standing at the far left red dot, and threw the ball up at an angle, the maximum height would be achieved at the blue dot, and it would hit the ground at the far right dot.

With a little help from physics, if you know the speed and angle of the ball when it left your hand, you can compute the maximum height, the time it takes to get to that height, and the time it takes to hit the ground, and the speed at any point. You can imagine how much the military uses this in their targeting systems.

hope it helps u

thanks for giving me a chance to help u
