Prove that the equation 2x^2 + 3xy - 2y^2 + 3x + y + 1 represents a pair of perpendicular lines and find the lines.

Answer»

$\underline{\textsf{To prove:}}$

$\textsf{The equation}\;\mathsf{2x^<klux>2</klux>+3xy-2y^2+3x+y+<klux>1</klux>=0}$

$\textsf{represents a pair of perpendicular ines}$

$\underline{\textsf{Solution:}}$

$\textsf{Concept:}$

$\textsf{The condition for the equation}\;\mathsf{ax^2+2hxy+by^2+2gx+2fy+c=0}$

$\textsf{represents a pair of perpendicular line is a+b=0}$

$\textsf{Comparing,}$

$\mathsf{2x^2+3xy-2y^2+3x+y+1=0}\;\textsf{with}$

$\mathsf{ax^2+2hxy+by^2+2gx+2fy+c=0}\;\textsf{we get}$

$\textsf{a=2, h=3/2, b=-2}$

$\textsf{Here, a+b=2+(-2)=0}$

$\therefore\textsf{The given equation represents a pair of perpendicular lines}$

$\textsf{Consider,}$

$\mathsf{2x^2+3xy-2y^2}$

$\mathsf{=2x^2+4xy-xy-2y^2}$

$\mathsf{=2x(x+2y)-y(x+2y)}$

$\mathsf{=(2x-y)(x+2y)}$

$\textsf{Now,}$

$\mathsf{2x^2+3xy-2y^2+3x+y+1=(2x-y+l)(x+2y+m)}$

$\textsf{Equating corresponding coefficients of x and y}$

$\textsf{on bothsides, we get}$

$\mathsf{l+2m=3}$ ....(1)

$\mathsf{2l-m=1}$ ......(2)

$\textsf{Solving (1) and (2)}$

$\mathsf{l+2m=3}$

$\mathsf{4l-2m=2}$

$\textsf{Adding,}$

$\mathsf{5\,l=5\implies\;l=1}$

$\mathsf{(2)\implies\;2-m=1\implies\;m=1}$

$\therefore\textsf{The separate equations are}$

$\textsf{2x-y+1=0 and x+2y+1=0}$

a wooden toy rocket in the shape of a cone mounted on a cylinder. the height of the entire rocket is 26 cm while the height of the. conical part is 6cm. the base of the conical portion has a diameter of 5 cm while the base diameter of the cylindrical portion is 3cm

Answer»

Answer:

Area to be painted ORANGE = Curved surface area of the cone + Base area of the cone − Base area of the CYLINDER

Area to be painted yellow = Curved surface area of the cylinder + Area of ONE BOTTOM base of the cylinder

Curved surface area of cone =πrl

l=62+2.52

l=36+6.25

l=42.25

l=6.5 cm

Curved surface area of cone =3.14×2.5×6.5

=51.025 cm2

Base area of cone = Area of CIRCLE

=πr2

=3.14×(2.5)2

=3.14×6.25

=19.625 cm2

Curved surface area of cylinder =2πrh

=2×3.14×1.5×20

=188.4 cm2

Base area of cone = Area of circle

=πr2

=3.14×(1.5)2

=7.065 cm2

Area to be painted orange = Curved surface area of the cone + Base area of the cone − Base area of the cylinder

=51.025+19.625−7.0625

=63.59 cm2

Area to be painted yellow = Curved surface area of the cylinder + Area of one bottom base of the cylinder

=188

Find the value of k so that the equation 3k2 + kx + 2 has equal roots

Answer»

Answer:

2√6

Step-by-step explanation:

Here your equation is 3k^2+kx+2, and. it has equal roots...

If it has equal roots then the value of d that is discriminant will be 0....

We know that d=b^2-4ac

It can be written as b^2-4ac = 0

put the values...

a=3, b=k, and c=2

therefore, k^2 - 4*3*2 = 0

k^2 - 24 = 0

and k^2 = 24

so, k will be √24 that can also be written as 2√6

so k=2√6...

Answer» Answer: 10 & 15 & 28 Step-by-step explanation: Let the price of pencil be RS a. So, Price of pen = 5 more than a = a + 5 Price of book = 8 + 2 times of a = 2A + 8 Total amount = Rs 53 = > price of pencil + price of pen + price of book = Rs 53 = > a + (a + 5) + (2a + 8) = 53 = > a + a + 2a + 13 = 53 = > 4a = 53 - 13 = 40 = > a = 40/4 = 10 (A): price of pencil = a = Rs 10 (B): price of pen = a + 5 = 10+5 = Rs 15 (C): 2a + 8 = 2(10)+8 = 28

The price of a pen is 5 rupees more than that of a pencial. The price of a book is 8 rupees more than twice of the price of a pencial. A man bought each of these iteams. It cost him 53 A.)what is the price of a pencial?B.)what is the price of a pen? C.)what is the price of a book?

Answer»

Answer:

10 & 15 & 28

Step-by-step explanation:

Let the price of pencil be RS a.

So,

Price of pen = 5 more than a = a + 5

Price of book = 8 + 2 times of a = 2A + 8

Total amount = Rs 53

= > price of pencil + price of pen + price of book = Rs 53

= > a + (a + 5) + (2a + 8) = 53

= > a + a + 2a + 13 = 53

= > 4a = 53 - 13 = 40

= > a = 40/4 = 10

(A): price of pencil = a = Rs 10

(B): price of pen = a + 5 = 10+5 = Rs 15

(C): 2a + 8 = 2(10)+8 = 28

44.	If the zeros of polynomial p(X)=X2 + 4x + 2a are a and 2/a find value of a
Answer» SOLUTION :- comparing the given quadratic POLYNOMIAL p(x) = x² + 4x + 2A with ax² + bx + c , we get, → a = 1 → b = 4 → c = 2a Now, we know that, sum of zeros of quadratic polynomial ax² + bx + c is (-b/a) . and, we have given that, zeros of given polynomial are a and (2/a) . So, → (a + 2/a) = (-b/a) → (a² + 2)/a = (-4/1) → a² + 2 = - 4a → a² + 4a + 2 = 0 Now ,using Sridharacharya formula for Solving Quadratic Equation ax² +bx + c = 0 we get :- x = [ -b±√(b²-4AC) / 2a ] x = [ - b ± √D /2a ] where D(Discriminant)= b²- 4ac. Now, we have :- a = 1 b = 4 c = 2 So, → D = b² - 4ac → D = 4² - 412 → D = 16 - 8 → D = 8 Therefore, → a = [ - b ± √D /2a ] → a = [ - 4 ± √8 ] / 21 → a = ( - 4 ± 2√2 ) /2 → a = (- 4 + 2√2)/2 or , (-4 - 2√2)/2 → a = (-2 + √2) or, (-2 - √2) (Ans.)*

If the zeros of polynomial p(X)=X2 + 4x + 2a are a and 2/a find value of a

Answer»

SOLUTION :-

comparing the given quadratic POLYNOMIAL p(x) = x² + 4x + 2A with ax² + bx + c , we get,

→ a = 1

→ b = 4

→ c = 2a

Now, we know that, sum of zeros of quadratic polynomial ax² + bx + c is (-b/a) .

and, we have given that, zeros of given polynomial are a and (2/a) .

So,

→ (a + 2/a) = (-b/a)

→ (a² + 2)/a = (-4/1)

→ a² + 2 = - 4a

→ a² + 4a + 2 = 0

Now ,using Sridharacharya formula for Solving Quadratic Equation ax² +bx + c = 0 we get :-

x = [ -b±√(b²-4AC) / 2a ]
x = [ - b ± √D /2a ] where D(Discriminant)= b²- 4ac.

Now, we have :-

a = 1
b = 4
c = 2

So,

→ D = b² - 4ac

→ D = 4² - 4*1*2

→ D = 16 - 8

→ D = 8

Therefore,

→ a = [ - b ± √D /2a ]

→ a = [ - 4 ± √8 ] / 2*1

→ a = ( - 4 ± 2√2 ) /2

→ a = (- 4 + 2√2)/2 or , (-4 - 2√2)/2

→ a = (-2 + √2) or, (-2 - √2) (Ans.)
