Can someone show me way of solving this​

Step-by-step explanation:

f(x) =  ln( \frac{1}{x} )

To find the derivative, notice we have a function 1/x inside of another function, ln(x)

We use what we call the chain rule,

It states that

derivative of a '

\frac{d}{dx} f(g(x)) =  f '(g(x)) \times \: g '(x)

Here f is ln(x)

f is 1/x

So first, we know that

\frac{d}{dx} ( ln(x)  =  \frac{1}{x}

so

f'(g(x)) =  \frac{1}{ \frac{1}{x} }

We know that

g'(x) =  - \frac{1}{ {x}^{2} }

So we have

x \times  -  \frac{1}{ {x}^{2} }  =   \frac{ - 1}{x}

If the limit of f(x) as x approaches 8 is 3, can you conclude anything about f(8)?
natali 33 [55]

If the limit of f(x) as x approaches 8 is 3, can you conclude anything about f(8)? The answer is No. We cannot. See the explanation below.

<h3>What is the justification for the above position?</h3>

Again, 'No,' is the response to this question. The justification for this is that the value of a function does not depend on the function's limit at a given moment.

This is particularly clear when we consider a question with a gap. A rational function with a hole is an excellent example that will help you answer this question.

The limit of a function at a position where there is a hole in the function will exist, but the value of the function will not.

<h3>What is limit in Math?</h3>

A limit is the result that a function (or sequence) approaches when the input (or index) near some value in mathematics.

Limits are used to set continuity, derivatives, and integrals in calculus and mathematical analysis.

42°

Step-by-step explanation:

\angle BAE =180\degree -132\degree

(Angles in linear pair)

\angle BAE =48\degree

\angle AEB =90\degree..(\because \overrightarrow{EC}\perp\overrightarrow{ED})

\angle ABE = 180\degree-(48\degree+90\degree)

(Angle sum postulate of a triangle)

\implies\angle ABE = 180\degree-138\degree

\implies\angle ABE = 42\degree

\angle CDE =\angle ABE = 42\degree

(corresponding angles)

\implies x\degree=\angle CDE

(vertical angles)

\implies x\degree=42\degree

\implies x=42
