TAKING L.H.S

\bold{2sin²}\dfrac{π}{6}\bold{+\:cosec²\:}\dfrac{7π}{6}\bold{cos²}\dfrac{π}{3}

⠀⠀⠀⠀⠀⠀⠀⠀

putting π = 180°

⠀⠀⠀⠀⠀⠀⠀⠀

= \bold{2sin²}\dfrac{180}{6}\bold{+\:cosec²}\dfrac{7\:×\:180}{6}\bold{cos²}]\dfrac{180}{3}

=\bold{2sin² \:30° \:+ cosec² \:210°\:cos² \:60}

=\bold{2(<klux>SIN</klux>\:30°)²\:+\:(cosec\:210°) \: (cos\:60°)²}

⠀⠀⠀⠀⠀⠀⠀⠀

Here,

\bold{sin\:30°\:=}\dfrac{<klux>1</klux>}{2}& \bold{sin\:cos\:60°=}\dfrac{1}{2}

⠀⠀⠀⠀

For cosec 210°

⠀⠀⠀⠀⠀⠀let's first calculate sin 210°

⠀⠀⠀⠀⠀⠀sin 210° = \bold{sin\:(180+30)}

⠀⠀⠀⠀⠀⠀= \bold{- \:sin 30°}

⠀⠀⠀⠀⠀⠀= \dfrac{-1}{2}

⠀⠀⠀⠀⠀

So,

cosec 210° = \dfrac{1}{sin\:210°}

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

\text{\large\underline{\red{putting\: values\: in \:equation}}}

⠀⠀⠀⠀⠀⠀⠀⠀

\bold{=\:2(sin\:30°)2 \:+ \:(cosec\:210°)? \:(cos\: 60°)²}

⠀⠀⠀⠀⠀= 2 \dfrac{1²}{2}+\bold{(-2)²}\dfrac{1²}{2}

⠀⠀⠀⠀⠀⠀⠀\bold{=\:2\:×}\dfrac{1}{2}+ 4 ×\dfrac{1}{2}

⠀⠀⠀⠀⠀⠀= \dfrac{1}{2} + 1

⠀⠀⠀⠀⠀⠀= \dfrac{1}{2} + 1

⠀⠀⠀⠀⠀⠀= \dfrac{3}{2}

⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀\bold{= \:R.H.S}

3. WRITE the following EQUATIONS in statement forms.

  • A):2X+9=34 = 2 multiply by x and add 9 so the answer is 34

  • B): 6-3X=20 = 3 multiply by x.. Subtract 6 you will get 20.

4. Check whether the VALUE given in the bracket is a solution to the given equations or not

A) 2X-1=5. (X=6).

2x - 1 = 5

2x= 6

X= 3

The cost price of a special issue of a bookwas 1980. The bookseller announced amarked price on it and gave a discount of12=% on the marked price. Even after thediscount, the bookseller makes a profit of10% on his cost price. Find the marked priceof the book.​

Answer»

Answer:

16,500 RS

Step-by-step explanation:

GIVEN,

CP = 1980 RS

discount % = 12%

Let the marked price be ' c '

so,

SP = MP OF D%

= c * 12/100 = 1980

= c= 1980 * 100/12

= c = 165 * 100/1

= c = 16,500

therefore the MP = 16,500 RS

Tap ‘A’ can fill an empty water tank in 12 hours while tap ‘B’ can fill it 4 in 15 hours. If both the taps are opened together and after 3 hours,tap ‘B’ is closed then find in what time tap ‘A’ will fill the remaining tank?

Answer»

Answer:

the tank is FULL now

Step-by-step explanation:

A takes 12

B takes 4

when we DIVIDE each other means

12÷4 =3 hours

it means 1h of B =3h of A

And if both are OPEN for 3h

then we have to understand that if B takes only 4h and 3h of A TAP = 1h of B tap then

3h of B + 3h of A

3h of B + 1h of B (because 3h of A tap = 1h of B tap)

3h + 1h = 4h of B tap then the tank is full

Find the equation of all line having slope - 1 thatare tangent to curve y=1/x-1. xnot equal to 1​

Answer»

\huge{\underline{\underline{\sf{\pink{Solution:-}}}}}

It is given that y = 1/(x - 1) , x ≠ 1

differentiate y with RESPECT to x,

dy/dx = -1/(x - 1)² , x ≠ 1

so, slope of TANGENT of the curve at (x,y) = dy/dx

= -1/(x - 1)²

A/C to QUESTION,

we equation of all lines having slope -1 that are TANGENTS to the curve, y = 1/(x -1) , x ≠ 1.

so, slope of tangent = - 1

=> -1/(x - 1)² = -1

=> (x - 1)² = 1

square root both sides,

x - 1 = ± 1,

x = 1 ± 1 = 0, 2

put x = 0, in the curve y = 1/(x - 1)

y = 1/(0 - 1) = -1

now equation of line passing through (0,-1) :

(y + 1) = -1(x - 0)

=> y + 1 + x = 0

hence, equation is x + y + 1 = 0

x+y+1=0

put x = 2, in the curve y = 1/(x - 1)

y = 1/(2 - 1) = 1

now equation of line passing through (2,1) :

(y - 1) = -1(x - 2)

=> y - 1 + x - 2 = 0

=> x + y - 3 = 0

hence, equation is x + y - 3 = 0

x+y−3=0

The area of a rectangle gets reduced by 9 square units, if its length isreduced by 5 units and the breadth is increased by 3 units. The area isincreased by 67 square units if length is increased by 3 units and breadth isincreased by 2 units. Find the perimeter of the rectangle. [CBSE 2012]​

Answer»

\huge\red{\tt{\underline{Solution:-}}}

Let length and breadth of rectangle be x UNIT and y unit.

Area = xy

According to the question,

⇒ (x - 5) (y + 3) = xy - 9

⇒ 3x - 5y - 6 = 0 ... (i)

⇒ (x + 3) (y + 2) = xy + 67

⇒ 2x - 3y – 61 = 0 ... (II)

By cross multiplication, we get

⇒ x/305 - (-18) = y/-12 -(-183) = 1/9 - (-10)

⇒ x/323 = y/171 = 1/19

{\fboxed{ x = 17, y = 9}}

Length of the rectangle = 17 units.

Breadth of the rectangle = 9 units.

Neha sold her old bicycle suffering aloss of 6%. If she had sold her bicyclefor 90 more, she would have made aprofit of 3%. Find the cost price of thebicycle.​

Answer»

Answer:

let the cost price be X and sp be y

loss % = CP - sp/ cp *100

6/100 = x-y/ x

6x =100x-100y

6x -100x=-100y

-94x=-100y

y=94x/100

3% profit=(y+90)-x/x

3/100=(y+90)-x/x

3x=100y +9000-100x

103x=100(94x/100)+9000

9x =9000

x =1000

hence cp =₹1000
