Draw the graph of the equation Y = 3 x​

Answer»

Step-by-step explanation:

To graph a linear equation Y=3x MEANS to draw a LINE in the 2-D plane. Notice that the intercept on y-axis is 0 meaning the line will pass through the ORIGIN and slope of line is 3. HOWEVER, graphing this line is fairly straightforward. For every VALUE of x in real number, Y is 3 times that value of x.

Range of f(x) = 1 - | x - 2 |​

Answer»

Answer:

range is integers.

Step-by-step explanation:

f(x)=1-|x-2|

now,

|x-2| => x-2 or -(x-2)

let .....

=> f(x) = 1 - (x-2)

f(x) = 1 - x + 2 = -x +3

f(1) = -1 + 3 = 2 ........

=> f(x) = 1 - (- (x-2))

f(x) = 1 + x -2 = x -1

f(1) = 1-1 = 0 .........

if range R is natural numbers

then,

range R is whole numbers.

if range R is whole numbers

then,

range R is integers.

A positive integer whose sum is -5​

Answer»

Answer:

Positive integer = 6

Negative Integer = -11

Step-by-step explanation:

Positive INTEGERS : The positive integers are the numbers 1, 2, 3, ... sometimes called the counting numbers or natural numbers, denoted +Z . They are the solution to the simple linear RECURRENCE equation.

Negative Integers : The negative integers are the numbers -1, -2, -3, ... sometimes called the counting numbers or natural numbers, denoted -Z . They are the solution to the simple linear recurrence equation.

Now, We need to find a negative and positive integer such that their sum is -5

Let positive integer be X and negative integer be y

Take x = 6

⇒ 6 + y = -5

⇒ y = -5 - 6

⇒ y = -11

So, Positive integer = 6

Negative Integer = -11

Sin2a+sin2b+sin2c=4cosacosbcosc​

Answer»

Answer:

SIN(2A) + sin(2B) - sin(2C) = 2SIN(A + B)*cos(A - B) - 2*sin(C)*cos(C) 

WKT for a TRIANGLE  A + B + C = 180°, A + B = 180° - C 

==> sin(A + B) = sin(180° - C) = sin(C)  

Also cos(C) = cos{180° - (A + B)} = -cos(A + B)  

Thus , sin(2A) + sin(2B) - sin(2C) = 2sin(C)*cos(A - B) - 2*sin(C)*cos(C)  

= 2sin(C){cos(A - B) - cos(C)}  

= 2sin(C){cos(A - B) + cos(A + B)}  

= 2sin(C)*2cos(A)*cos(B) [Identity]  

= 4*cos(A)*cos(B)*sin(C)  

Thus sin(2A) + sin(2B) - sin(2C) = 4*cos(A)*cos(B)*sin(C)

If x=root 2+1 ,find the value of x+1/x

Answer»

\mathfrak{\large{\underline{\underline{Answer:-}}}}

\boxed{ \tt x +  \dfrac{1}{x} = 2 \sqrt{2} }

\mathfrak{\large{\underline{\underline{Explanation:-}}}}

GIVEN :- \tt x = \sqrt{2} + 1

To find :- \tt x + \dfrac{1}{x}

Solution :-

FIRST find the VALUE of 1/x

\tt \dfrac{1}{x} =  \dfrac{1}{ \sqrt{2} + 1}

Rationalise the denominator

The rationalising FACTOR of √2 + 1 is √2 - 1. So multiply both numerator and denominator with rationalising factor

\tt  = \dfrac{1}{ \sqrt{2} + 1} \times  \dfrac{ \sqrt{2} - 1}{ \sqrt{2} - 1}

\tt =  \dfrac{ \sqrt{2} - 1}{( \sqrt{2} + 1)( \sqrt{2} -1)}

\tt =  \dfrac{ \sqrt{2} - 1}{ {( \sqrt{2})}^{2} -  {1}^{2}  }

[SINCE (x + y)(x - y) = x² - y² and here x = √2 and y = 1]

\tt =  \dfrac{ \sqrt{2} - 1}{2 - 1}

\tt =  \dfrac{ \sqrt{2} - 1}{1}

\tt =  \sqrt{2} - 1

So we got value of 1/x as √2 - 1

Now we know values as \bf x =  \sqrt{2} + 1, \:  \dfrac{1}{x} =  \sqrt{2} - 1

So now we can find x + 1/x

\tt x +  \dfrac{1}{x} = \sqrt{2} + 1 + ( \sqrt{2} - 1)

\tt =  \sqrt{2} + 1 +  \sqrt{2} - 1

\tt  =  \sqrt{2} +  \sqrt{2}

\tt = 2 \sqrt{2}

\Huge{\boxed{ \sf x +  \dfrac{1}{x} = 2 \sqrt{2} }}

Answer»

Answer:

Step-by-step explanation:

f(x)=4x²-5x-1

αβ are ZEROS of f(x)

so αβ=-1/4,α+β=5/4

=========================

(α-β)²=α²+β²-2αβ

=α²+β²+2αβ-4αβ

=(α+β)²-4αβ

=(5/4)2-4*-1/4

=25/16+1=41/16

so α-β=√41/16=√41  /4

==============================

(ii) α²-β²=(α-β)(α+β)

=√41 /4 *5/4

=5√41 / 16

============

(III)

1/α+1/β

=1/αβ(α+β)

=(5/4) /(-1/4)

=-5

=======

)iv)

1/α-1/β

=1/αβ(β-α)

=(-1/4)(-5/4)

=5/16

==============

(V)

α/β-β/α

=1/αβ(α²-β²)

=(1/ (-1/4) ( 5√41 /16) ( from SOLUTION(ii) )

=-4*5√41 /16

= -5√41 /4

=================

(vi)

1/α-1/β-2αβ

=1/αβ(β-α-2α²β²)

Putting the values

=1/ (-1/4)[ -(α-β)-2α²β² ]

=-4 [ -√41  /4-2*(1/4)² ]

=-4( -√41  /4 -1/8)

=-4*8( -2√41 -1)

=32(2√41  +1)

Plzzzzzzz help me urgent​

Answer»

Answer:

Step-by-step EXPLANATION:

sin(B+C-A)=COS(C+A-B)=tan(A+B-C)=1

Since sin(B+C-A)=1 hence B+C-A=90⁰,……(i)

cos(C+A-B)=0 hence C+A-B=0⁰……….(ii)

tan(A+B-C)=1 hence A+B-C=45⁰………..(iii)

Adding (i)and(ii)GIVES 2C=90⁰ hence C =45⁰

Adding (ii) and ( iii) gives 2A= 45⁰ hence A=22.5⁰

From (i) B=90⁰+A-C=90⁰+22.5⁰–45⁰=67.5⁰
