What is the sum of 1/4 and 1/5?

1 answer:

3 0

To add them, you first need a common denominator.
So multiply <span> 1/4 by 5/5 and 1/5 by 4/4 first.

Now they'll be 5/20 and 4/20.

Add them to get 9/20. </span>

The value of the expression will be 2. Then the correct option is B.

The complete question is given below.

<h3>What is the limit?</h3>

The value that approaches the output for the given input value. Limits are a very important tool in calculus.

The expression is given below.

$\rightarrow \displaystyle \lim_{x \to 0}\dfrac{\cos x \ \tan 2x}{x}$

Then the value of the expression will be

Applying L'hospital rule, then we have

$\rightarrow \displaystyle \lim_{x \to 0}\dfrac{\dfrac{d}{dx} \cos x \ \tan 2x}{\dfrac{d}{dx}x}\\\\\\\\\rightarrow \displaystyle \lim_{x \to 0}\dfrac{2 \cos x \sec^2 2x - \sin x \ \tan 2x}{1}\\$

Put the limit, then we have

⇒ 2 × cos 0 × sec² (2 × 0) – sin 0 × tan (2 × 0)

⇒ 2 × 1 × 1 – 0

⇒ 2

Then the correct option is B.
