Answer»

2x^{2}+7x+3=0

2x^{2} +6X + x + 3 =0

2x(x +3) +1(x+3) =0

(2x+1)(x+3) = 0

2x +1 =0

x =  \frac{-1}{2}

x+3 =0

x = -3

The VALUES of x are \frac{-1}{2} and -3

3.

A tent in the shape of cylinder surmounted by a conical top. If the height and diameter of the cylindrical part are 3.5 m and 6 m respectively, and the slant height of the top is 2.8 m. Find the area of the canvas used for making the tent. Also, find the cost of the canvas of the tent at the rate of 500 per m2

Answer»

Given -

  • Height of cylindrical part = 3.5m

  • Radius of Cylindrical part = 6/2 = 3m

  • Slant Height of conical part = 2.8m

To find -

  • Area of canvas and RATE.

Solution -

First we will find the curved surface area of cylindrical and conical parts.

So,

Curved surface area of cylinder = 2πrh

where,

π = \dfrac{<klux>22</klux>}{7}

r = radius

h = height

On substituting the VALUES -

CSA = 2πrh

CSA = 2 × \dfrac{22}{7} × 3 × 3.5m

CSA = 2 × 22 × 3 × 0.5m

\longmapsto CSA = 66m²

Similarly,

Curved surface area of cone = πrl

where,

π = \dfrac{22}{7}

r = Radius

l = slant Height

On substituting the values -

CSA = πrl

CSA = \dfrac{22}{7} × 3 × 2.8

CSA = 22 × 3 × 0.4

\longmapsto CSA = 226.4m²

Area used for making canvas = CSA of cylindrical part + CSA of conical part

\longmapsto 66m + 226.4m

\longmapsto 92.4m²

Cost of canvas of tent = Rate given × total area

\longmapsto 500 × 92.4

\longmapsto ₹46200

\thereforeArea for making canvas is 92.4m³ and cost is 46200

If sin(A – B) = ½ ; cos(A + B) = ½ . Find the values of A and B.​

Answer»

ANSWER:

GIVEN that

\sin(A - B)  =  \dfrac{1}{2}  \\  \\  \cos(A + B)  =  \frac{1}{2}

Now

\sin(A  - B)  =  \dfrac{1}{2} \:  \:  \:  \:  \:  \:  \:  . .........(1)\\  \\ and \: as \: we \: know \\  \\ sin30 \degree =  \dfrac{1}{2} \:  \:  \:  \:  \:  \:  \:  \:  \: ..........(2)  \\  \\ so \: using \: (1)  \: and  \: (2) \\  \\ A - B = 30 \degree \:  \:  \:  \:  \:  \: ..........(<klux>3</klux>)

And

\cos(A + B)  =  \dfrac{1}{2}   \:  \:  \:  \:  \:  \:  \: .........(4)\\  \\

cos60 \degree =  \dfrac{1}{2}  \:  \:  \:  \:  \:  \: ........(5)

using \: (4)  \: and  \: (5) \\  \\ A + B = 60 \degree \:  \:  \:  \:  \:  \:  \: .......(<klux>6</klux>)

Adding (3) and (6)

We get

2A = 90 \degree \\  \\ \boxed{ \boxed{ A = 45 \degree}}

Putting VALUE of A in (6)

\boxed{  \boxed{ B = 15 \degree}}

Answer»

Answer:

Limiting friction is equal to sliding friction

CALLED limiting friction.

When the applied FORCE, F, is increased further (BEYOND the limiting frictional force), the BODY begins to MOVE, then the force opposing the motion is called the kinetic or sliding friction. The kinetic friction is less than the limiting friction.

Find the roots of quadratic eqution 4x²-12x -9=0​

Answer»

APPROPRIATE EQUATION

4x²- 12x + 9 = 0

To Find

The roots of quadratic eqution.

SOLUTION

4x²- 12x + 9 = 0

Splitting the middle term,

=> 4x² - 6X - 6x + 9 = 0

=> 2x(2x - 3) - 3(2x - 3) = 0

=> (2x - 3)(2x - 3) = 0

=> 2x - 3 = 0

=> X = 3/2.

or,

=> 2x - 3 = 0

=> x = 3/2.

The roots of the equation

4x²- 12x + 9 = 0 is 2/3.

Findthe polynomialequation whoseroots are thereciprocalsof therootsofx⁴-3x³+7x²+5x-2=0​

Answer»

The GIVEN equation is x 2 −3x−4=0

x² −3x−4=0

⇒ x 2 −4x+x−4=0

⇒ x(x−4)+1(x−4)=0

⇒ (x−4)(x+1)=0

⇒ x=4 and x=−1

Taking RECIPROCAL of roots we get,

⇒ x= 1/4 and x=−1

The required equation,

⇒ (x− 4/1) (x+1)=0

⇒ x² +x - x/4 - 1/4 =0

⇒ 4x²+4x−x−1=0 [ MULTIPLYING both SIDES by

4 ]

∴ 4x² +3x−1=0

(iii) -37 from -53 subtract​

Answer»

Answer:

0

Step-by-step explanation:

To solve the problem 37 minus 37 USING long subtraction, we first put the largest number on TOP and the smallest number at the bottom like this:

       37   -   37         

Then you subtract the ones digits (7 - 7 = 0) like this:

       37   -   37        0

Next you subtract the tens digits (3 - 3 = 0) like this:

       37   -   37       00

And that's it. The problem with the answer is displayed below:

37 - 37 = 0

Prove that (x-1) is a factor of x^17-1.please friends urgent​

Answer»

Note :

★ Remainder theorem : If a polynomial p(x) is DIVIDED by (x - c) , then the remainder OBTAINED is given as R = p(c) .

FACTOR theorem :

If the remainder obtained on dividing a polynomial p(x) by (x - c) is zero , ie. if R = p(c) = 0 , then (x - c) is a factor of the polynomial p(x) .

If (x - c) is a factor of the polynomial p(x) , then the remainder obtained on dividing the polynomial p(x) by (x - c) is zero , ie. R = p(c) = 0 .

Solution :

  • Given polynomial : x^(17) - 1
  • To prove : (x - 1) is a factor of x^(17) - 1

Proof :

Let the given polynomial be ;

p(x) = x^(17) - 1

Also ,

If x - 1 = 0 , then x = 1

Now ,

By remainder theorem , the remainder on diving the given polynomial p(x) by (x - 1) will be given as ;

=> R = p(1)

=> R = 1^(17) - 1

=> R = 1 - 1

=> R = 0

Since ,

The remainder obtained on dividing [x^(17) - 1] by (x - 1) is zero , thus (x - 1) is a factor of [x^(17) - 1] .

Hence proved .
