Given f(x)=sec x and g(x)=arcsin x, what is f(g(x))?

Dominik [7]

Answer:

Option 1 is correct.

Step-by-step explanation:

Given two functions f(x)=sec x and g(x)=arcsin x

we have to find f(g(x)).

f(g(x))=sec(arcsinx)=sec A where A=arc(sinx)

As, A=arc(sinx)

⇒ $x=sin A=\frac{P}{H}$

⇒ P=x and H=1 gives $B=\sqrt{1-x^2}$

hence, $sec A=\frac{H}{B}=\frac{1}{\sqrt{1-x^2}}$

hence, $f(g(x))=\frac{1}{\sqrt{1-x^2}}$

Rationalizing, we get

$f(g(x))=\frac{\sqrt{1-x^2}}{1-x^2}$

Option 1 is correct.

I need some help please!

Answer:

See below

Step-by-step explanation:

Given :-

y || z

To Prove :-

m∠5 + m∠2 + m∠6 = 180°

Proof :-

Here we are required to prove that ,

$\rm\implies m\angle 5 + m\angle 6 + m\angle 2 = 180^o$

And here it's given that , y || z . Therefore ,

∠3 = ∠6 ( alternate interior angles )
∠1 = ∠5 ( alternate interior angles )

Now we know that the measure of a straight line is 180°. Therefore ,

$\rm\implies m\angle 1 + m\angle 2 + m\angle 3 = 180^o \\\\\implies\boxed{\rm m\angle 5 + m\angle 6 + m\angle 2 = 180^o}$

From 1 and 2 .

Hence Proved !
