4.	27 help me to solvent dear friends
Answer» Step-by-step explanation: (2X)² + (3y)² + (4z)² - (2x) (3y) - (3y) (4z) - (2z) (4x) =0 [1/2× (2x-3y)² +. (3y-4z)²+ (4z-2x)²] = 0 (3x-3y)² + (3y-4z)² + (4z-2x)² = 0 sum of squares can't be zero so this means all are 0. 2x=3y & 3y=4z 2x=3y=4z=k so, x=k/2, y=3/2, Z= k/4 so, x,y,z are in h.p H.p means in harmonic progression.

27 help me to solvent dear friends

Answer»

Step-by-step explanation:

(2X)² + (3y)² + (4z)² - (2x) (3y) - (3y) (4z) - (2z) (4x) =0

[1/2× (2x-3y)² +. (3y-4z)²+ (4z-2x)²] = 0

(3x-3y)² + (3y-4z)² + (4z-2x)² = 0

sum of squares can't be zero so this means all are 0.

2x=3y & 3y=4z

2x=3y=4z=k

so, x=k/2, y=3/2, Z= k/4

so, x,y,z are in h.p

H.p means in harmonic progression.

I hope this will help you.

Answer» $\large\underline{\bf{Solution-}}$ Given that Marked Price OD Radio = RS 5000 DISCOUNT % = 15 % Vat % = 13 % We know, Selling Price including Vat is given by $\boxed{ \bf \:SP = \dfrac{(100 - d\%) \times (100 + v\%)}{100 \times 100} \times <klux>MP</klux>}$ where, SP = Selling Price d % = Discount % v % = Vat % MP = Marked Price On substituting all the values in above formula, we GET $\rm :\longmapsto\:{\rm\:SP = \dfrac{(100 - 15) \times (100 + 13)}{100 \times 100} \times 5000}$ $\rm :\longmapsto\:{\rm\:SP = \dfrac{85 \times 113}{2}}$ $\bf\implies \:SP = 4802.50$ Hence, $\: \: \: \: \: \: \underbrace{ \boxed{ \bf{Selling \: Price \: of \: radio = Rs \: 4802.50}}}$ Additional Information :- $\begin{gathered}\: \: \: \: \: \: \begin{gathered}\begin{gathered} \footnotesize{\boxed{ \begin{array}{cc} \small\underline{\frak{\pmb{ \red{More \: Formulae}}}} \\ \\ \bigstar \: \bf{Gain = \sf S.P. \: – \: C.P.} \\ \\ \bigstar \:\bf{Loss = \sf C.P. \: – \: S.P.} \\ \\ \bigstar \: \bf{Gain \: \% = \sf \Bigg( \dfrac{Gain}{C.P.} \times 100 \Bigg)\%} \\ \\ \bigstar \: \bf{Loss \: \% = \sf \Bigg( \dfrac{Loss}{C.P.} \times 100 \Bigg )\%} \\ \\ \\ \bigstar \: \bf{S.P. = \sf\dfrac{(100+Gain\%) \: (or) (100 - Loss\%)}{100} \times C.P.} \\ \: \end{array} }}\end{gathered}\end{gathered}\end{gathered}$

the market price if a radio was rs 5000 .what will be the price of the radio.if 13% VAT was levied after allowing 15% discount on it?

Answer»

$\large\underline{\bf{Solution-}}$

Given that

Marked Price OD Radio = RS 5000

DISCOUNT % = 15 %

Vat % = 13 %

We know,

Selling Price including Vat is given by

$\boxed{ \bf \:SP = \dfrac{(100 - d\%) \times (100 + v\%)}{100 \times 100} \times <klux>MP</klux>}$

where,

SP = Selling Price

d % = Discount %

v % = Vat %

MP = Marked Price

On substituting all the values in above formula, we GET

$\rm :\longmapsto\:{\rm\:SP = \dfrac{(100 - 15) \times (100 + 13)}{100 \times 100} \times 5000}$

$\rm :\longmapsto\:{\rm\:SP = \dfrac{85 \times 113}{2}}$

$\bf\implies \:SP = 4802.50$

Hence,

$\: \: \: \: \: \: \underbrace{ \boxed{ \bf{Selling \: Price \: of \: radio = Rs \: 4802.50}}}$

Find the zeroes of the quadratic polynomial 9x2 – 6x + 1 and verify the relationship between the zeroes and the coefficients

Answer»

Step-by-step explanation:

GIVEN:-

The quadratic polynomial 9x^2 – 6x + 1

To FIND:-

Find the zeroes of the quadratic polynomial

9x^2 – 6x + 1 and VERIFY the relationship between the zeroes and the coefficients

Solution:-

Given quadratic polynomial is 9x^2-6x+1

=>P(x)= 9x^2 - 6x +1

=>P(x)= 9x^2 -3x -3x +1

=>P(x) = 3x ( 3x -1) -1( 3x-1)

=>P(x) = (3x - 1) (3x-1)

To get the zeores we can write P(x) = 0

=> P(x) = (3x - 1) (3x-1) = 0

=> 3x -1 = 0

=> 3x = 1

=> x = 1/3

The zeores are 1/3 and 1/3

Let α = 1/3 and β = 1/3

P(x)=9x^2 - 6x +1

On Comparing this with the standard quadratic Polynomial ax^2+bx+c

a = 9

b=-6

c=1

Sum of the zeros =

α + β = (1/3)+(1/3)

=> (1+1)/3

=> 2/3

=-(-6/9)

=> -b/a

α + β = b/a

Product of the zeroes = α β

α + β = (1/3)(1/3)

=> 1/9

=> c/a

α β = c/a

Verified the given relations between the zeroes and the coefficients of the given Polynomial.

Used formulae:-

Sum of the zeros = -b/a

Product of the zeroes = c/a

Answer» Concept:- Here, The all three sides of the isosceles TRIANGLE is given, we have to FIND the area of the isosceles triangle. For finding the area of the isosceles triangle we use HERON's Formula. Given:- Equal sides of the triangle is 18 cm. Third side of the triangle is 28 cm. [Note:- TAKE √2 = 1.41 ] To Find:- Area of the isosceles triangle ? Solution:- Here, We know the Heron's formula for isosceles triangle that is, $\sf{\Longrightarrow \sqrt{S (S - a)^{2} (S - b)}}$ $\sf{Where,\ S = \dfrac{2a + b}{2}}$ a is the equal side of the triangle b is the UNEQUAL side of the triangle. We have, a = 18 cm b = 28 cm $\sf{S = \dfrac{2 \times 18 + 28}{2}\ \ \Longrightarrow \ \ 32}$ Now, Putting all the values we get, $\sf{\Longrightarrow \sqrt{32 (32 - 18)^{2} (32 - 28)}}$ $\sf{\Longrightarrow \sqrt{32 \times (14)^{2} \times 4}$ $\sf{\Longrightarrow \sqrt{32 \times 196 \times 4}$ $\sf{\Longrightarrow \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 2 \times 7 \times 2 \times 2 \times 2}$ $\sf{\Longrightarrow \sqrt{\underline{2 \times 2} \times \underline{2 \times 2} \times \underline{2 \times 2} \times \underline{2 \times 2} \times \underline{7 \times 7} \times 2}$ $\sf{\Longrightarrow 2 \times 2 \times 2 \times 2 \times 7 \times \sqrt{2}$ $\sf{\Longrightarrow 112\sqrt{2}$ [ Taking √2 = 1.41 ] $\sf{\Longrightarrow 112 \times 1.41}$ $\sf{\Longrightarrow 157.92\ cm^{2}}$ Hence, Area of the isosceles triangle is 157.92 cm².

Find the area of an isosceles triangle, each of whose equal sides is 18 cm and base is 28cm. (Take 2 = 1.41)[Ans. 157.92 cm

Answer»

Concept:-

Here, The all three sides of the isosceles TRIANGLE is given, we have to FIND the area of the isosceles triangle. For finding the area of the isosceles triangle we use HERON's Formula.

Given:-

Equal sides of the triangle is 18 cm.
Third side of the triangle is 28 cm.

[Note:- TAKE √2 = 1.41 ]

To Find:-

Area of the isosceles triangle ?

Solution:-

Here, We know the Heron's formula for isosceles triangle that is,

$\sf{\Longrightarrow \sqrt{S (S - a)^{2} (S - b)}}$

$\sf{Where,\ S = \dfrac{2a + b}{2}}$

a is the equal side of the triangle

b is the UNEQUAL side of the triangle.

We have,

a = 18 cm

b = 28 cm

$\sf{S = \dfrac{2 \times 18 + 28}{2}\ \ \Longrightarrow \ \ 32}$

Now, Putting all the values we get,

$\sf{\Longrightarrow \sqrt{32 (32 - 18)^{2} (32 - 28)}}$

$\sf{\Longrightarrow \sqrt{32 \times (14)^{2} \times 4}$

$\sf{\Longrightarrow \sqrt{32 \times 196 \times 4}$

$\sf{\Longrightarrow \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 2 \times 7 \times 2 \times 2 \times 2}$

$\sf{\Longrightarrow \sqrt{\underline{2 \times 2} \times \underline{2 \times 2} \times \underline{2 \times 2} \times \underline{2 \times 2} \times \underline{7 \times 7} \times 2}$

$\sf{\Longrightarrow 2 \times 2 \times 2 \times 2 \times 7 \times \sqrt{2}$

$\sf{\Longrightarrow 112\sqrt{2}$ [ Taking √2 = 1.41 ]

$\sf{\Longrightarrow 112 \times 1.41}$

$\sf{\Longrightarrow 157.92\ cm^{2}}$

Hence, Area of the isosceles triangle is 157.92 cm².

Please tell me this page all answers please i request you

Answer»

Answer:

hey here are your answers

pls mark them as brainliest

Step-by-step explanation:

1.option a ie -3

2.it is 0

see let odd number be 1

and even as 2

then -1 will remain as it is same but due to square in ANOTHER -1 it will be converted to 1

so -1+1=0

3.option c ie 16/5

4.option d ie 10/18

5.option b ie 4x-5

6.option d ie x+7

7.option c ie 16

let three CONSECUTIVE numbers be x,,(x+1),,(x+2)

thus x+x+1+x+2=45

solve you get x=14

so the numbers would be 14 15 16

so 16 is greatest

8.option b ie right angle

9.option b ie 2

10.option b ie equal

11.option b ie bc

12.option a ie 1

see bcs sum of all angles in any triangle is 180

and obtuse measures more than 120 to 180

and if there would be two three obtuse angles the sum would go above 180 which is not possible

13.option b ie centroid

14.option a ie 6:5

use a/b/c/d property in this sum

15. option c ie 1000

because 1m=100 cm

but 1cm=10 mm

so 1m=100×10 mm

ie 1m=1000 mm

16.option c ie 100 %

17.option c ie pie chart

it is basically circle of SUITABLE RADIUS and circle is only group of non collinear points in which sectors arc segment can be plotted,, inscribed,, circumscribed

18.option b ie 2

19.option c ie 3

20.i think it must be 0 according to law of integers as 3+(-3) would cancel each other due to unlike terms

I hope my answrs were helpful to you
