1. 3sin:' x = sin' (3x - 4x3)

Answer»

★Correct Question★

${3} \<klux>SIN</klux> ^{ - 1} <klux>X</klux> = \sin {}^{ - 1} (3x - 4 {x}^{3} )$

★SolutiOn★

Let x = Sin ∅

Then,

$\sin {}^{ - 1} = ∅$

We have,RHS,

$\sin {}^{ - 1} (3x - 4 {x}^{3} )$

$= \sin {}^{ - 1} (3 \sin ∅- 4 \sin∅)$

$= \sin {}^{ - 1} \sin \: 3∅$

$= 3∅$

$= 3 \sin {}^{ - 1} x = LHS$

Prove that sin square theta + cos square theta is equal to 1

Answer»

To prove:

sin²x+cos²x=1

Proof 1:

Refer to attachment 1

When x=60°,

sin²60+cos²60

=(1/2)²+(√3/2)²

=1/4+3/4

=4/4

=1

When x=0°,

sin²0+cos²0

=1+0

=1

This is TRUE for all values of sin x and COS x.

Hence,proved

Proof 2:

Refer to attachment 2

Now,

sin x=AB/BC→sin²x=AB²/AC².......................(1)

cos x=AC/BC→cos²x=BC²/AC².........................(2)

Adding (1) and (2),

sin²x+cos²x

=AB²/AC²+BC²/AC²

=(AB²+BC²)/AC²

=AC²/AC²

=1

Hence,proved.

Here,

AB is the perpendicular,AC is the hypotenuse and BC is the base

Now,

In a right triangle,

Hypotenuse ²=Base²+Perpendicular ²

→AC²=AB²+BC²

22.

Note: Take the digits as x and 9-x

Answer»

Step-by-step explanation:

LET unit digit be x

TEN's digit be 9- x

original NUMBERS= 10 (9 - x ) + x

= 90 - 9x

REVERSE no. = 10x + 9 - x

=9x + 9

original no. - 27 = reverse no.

90- 9x -27=9x +9

63-9x = 9x + 9

63+9= 9x +9x

72 = 18x

72/18=x

4= x

unit digit = 4

ten's digit = 9-4

=5

therefore, the number is 54

13. If 3n = 27, then 3n-2 equals.43(c) 1(d)if 3 and if 3 ki power n is equal to 27 then 3 ki power n minus 2

Answer»

$\mathfrak {Yo \:Mate !}$

Your correct question :

If $\sf {3^{n} = <klux>27</klux>}$ , find the VALUE of $\sf {3^{n-2}}$

SINCE, I'm unaware of the correct question, I'll give the VALUES of both $\sf {3^{n} -2}$ and $\sf {3^{n-2}}$

Solution:-

$\sf {3^{n} = 27}$

=》 $\sf{3^{n} = 3^{2}}$

.•. n = 3

Now :-

$\sf {3^{n} -2}$

=》 $\sf {3^{3} - 2}$

=》 27 - 2

=》 25

And :-

$\sf {3^{n-2}}$

=》 $\sf {3^{3-2}}$

=》 3

Step-by-step EXPLANATION:

Let 1/x=a and 1/y=b

so FIRST EQUATION becomes

3a-1b=-9

second equation becomes

2a+3b=5

solving the equation by elimination

we get a= -2b=3

x=1/a=-1/2

y=1/b=1/3
