⠀⠀⠀⠀⠀⠀⠀⠀

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° = $\dfrac{1}{sin\:210°}$

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

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

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

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.

Answer»

Answer:

loss % = CP - sp/ cp *100

6x -100x=-100y
