What is a rationlising factor ?

If the product of two irrational numbers is a rational number then each of the the two is rationalising factor of the other.

What is the purpose of rationilising the denominator ?

If the denominator of a fraction is irrational it is somewhat difficult to locate the fraction on number line. So, to make it easy we need to rationalise the denominator.

How to rationalise the denominator ?

1) Consider the denominator of the fraction.

2) Then multiply the numerator and denominator with rationalising factor of the denominator.

Answer 2

Answer:

the range or the ball is 48.81 m

Explanation:

given;

Nicole throws a ball at 25 m/s at an angle of 60 degrees abound the horizontal.

find:

What is the range of the ball?

solution:

let Ф = 25°

Vo = 25 m/s

consider x-motion using time of fight: x = Vox * t

where x = R = range

t = 2 Voy

      g

R = Vo² sin (2Ф)

           g

plugin values into the formula:

R = (25)² sin (2*25)

               9.81

R = 48.81 m

therefore, the range or the ball is 48.81 m
