Distance between AANDB A =(4,-5) = (x1,y1) & B = (1,1) = (x2,y2). = rootover(x2-x1)^2+(y2-y1)^2 = rootover(1-4)^2+(1-(-5))^2 = rootover(-3)^2+(6)^2 = rootover9+36 = rootover45. 2. Distance between BandC B = (1,1) = (x1,y1) & C = (-2,7) = (x2,y2). =rootover(x2-x1)^2+(y2-y1)^2 = rootover(-2-1)^2+(7-1)^2 = rootover(-3)^2+(6)^2 = rootover9+36 = rootover45. 3. Distance between C and A C = (-2,7) = (x1,y1) & A = (4,-5) = (x2,y2). = rootover(x2-x1)^2+(y2-y1)^2 = rootover(4-(-2))^2+(-5-7)^2 = rootover(6)^2+(-12)^2 = rootover36+144 = rootover180 Distance between A and B = Distance between B and C not equal Distance between C and A. Therefore this three points are not collinear. I hope it is helps to you.

17.

Prove that the point (4,-5),(1,1) and(-2,7) are collinear ( by distance formula)

Answer»

ANSWER:-DISTANCE formula is

rootover( x2-x1)^2+(y2-y1)^2.

Given points are A = (4,-5)

B = (1,1)

C = (-2,7).

1. Distance between AANDB

A =(4,-5) = (x1,y1) & B = (1,1) = (x2,y2).

= rootover(x2-x1)^2+(y2-y1)^2

= rootover(1-4)^2+(1-(-5))^2

= rootover(-3)^2+(6)^2

= rootover9+36

= rootover45.

2. Distance between BandC

B = (1,1) = (x1,y1) & C = (-2,7) = (x2,y2).

=rootover(x2-x1)^2+(y2-y1)^2

= rootover(-2-1)^2+(7-1)^2

= rootover(-3)^2+(6)^2

= rootover9+36

= rootover45.

3. Distance between C and A

C = (-2,7) = (x1,y1) & A = (4,-5) = (x2,y2).

= rootover(x2-x1)^2+(y2-y1)^2

= rootover(4-(-2))^2+(-5-7)^2

= rootover(6)^2+(-12)^2

= rootover36+144

= rootover180

Distance between A and B = Distance between B and C not equal Distance between C and A.

Therefore this three points are not collinear.

I hope it is helps to you.

Use euclid's division algorithm to find the hcf of 136,170&255

Answer»

Answer:

I HOPE IST helpful plz MAKE me brinslint I NEED brinslint plz make me brinslint have a great day

Step-by-step EXPLANATION:

Euclid division lemma:-

a = bq + r

0 ≤ r < b

First,find the HCF of 255 and 170

» 255 = 170(1) + 85

170 = 85(2) + 0

HCF of 255 and 170 is 85

Now find the HCF of 136 and 85

» 136 = 85(1) + 51

85 = 51(1) + 34

51 = 34(1) + 17

34 = 17(2) + 0

HCF of 136 and 85 is 17

Therefore! HCF (136,170,255) = 17

ANSWER:

therefore, x = -9/2

Step-by-step explanation:

or, 4- 3x/2 = 3x+5

or, - 3x/2 = 3x +5-4

or, -3x /2 - 3x = 1

or, -3x/2 - (3x×2/1×2) = 1

or, -3x/2 - 6x/2 = 1

or, (-3x-6x)/2 = 1

or, -9x = 1/2

or, x = 1/2/(-9)

therefore, x = -9/2

JKLM is a trapezium where JK II ML. If the diagonals MK and JL intersect each other at N, then the value of MK x NL is always equal to

Answer»

Given : JKLM is a trapezium where JK || ML. If the DIAGONALS MK and JL intersect each other at N,

To Find : value of MK × NL is always equal to

Solution:

Comparing

ΔMNL with ΔKNJ

∠MNL = ∠KNJ ( vertically opposite angles)

∠NML = ∠NKJ ( alternate interior angles)

∠NLM = ∠NJK ( alternate interior angles)

=> ΔMNL ≈ ΔKNJ (AAA Similarity criteria)

=> MN/KN = NL/NJ

=> NL * NK = MN * NJ

=> NL * ( MK - MN) = MN * NJ

=> NL * MK - NL * MN = MN * NJ

=> NL * MK = MN * NJ + MN * NL

=> NL * MK = MN ( NJ + NL )

=> NL * MK = MN ( JL)

=> NL * MK = MN * JL

MK * NL = MN * JL

Find x and y by eliminationmethodX/2-y/9=6,X/7+y/3=5

Answer»

Answer:

x = 10

x = 10y = 9

Step-by-step explanation:

x/2 - y/9 = 6 -------- 1

x/7 + y/3 = 5 ------- 2

By taking LCM, solving 1 st equation

9x - 2y/18 = 6

9x-2y = 108 -------3.

By taking LCM, solving 2ND equation

3x + 7Y/21 = 5

3x + 7y = 105 ------- 4

now solve equation. 3 and 4 by elimination method

9x - 2y = 108

(-) (-) (-)

9x + 21y = 315 { 3x +7y = 105 (×3)}

–––––––––––

-23y = -207

–––––––––––

y = 9

sub y = 9 in equation 3

9x - 2(9) = 108

9x -18 = 108

9x = 108+18

9x = 126

x = 14

Therefore by solving x = 10, Y = 9

In the adjoining figure ,AOB is a straight line. Find the value of x .Hence ,find Angle AOC ,Angle COD and Angle BOD

Answer»

Answer:

HEY you can draw this figure we can clearly see what this FORMS are linear pair so simply

3 Multiple -7 +55+X+20=108degree

4multiple +68 = 180 gives > 4x=112 gives x= 28degree

so ANGLE AOC is equals to 3 into minus 7 is equals to 84 - 7 is equal to 77

Angle B O D is equals to 2 X + 20 e equals to 28 + 20 e is equals to 48 degree

2. Find p(3), p(0) and p(-2) for the polynomials(i) x2 + 7(ii) 3x - 1

Answer»

Answer:-

(i) p(x) = x² + 7

p(3) = (3)² + 7

= 9 + 7

= 16

p(0) = (0)² + 7

= 0 + 7

= 7

p(-2) = (-2)² + 7

= 4 + 7

= 11

(ii) p(x) = 3x - 1

p(3) = 3 × (3) - 1

= 9 - 1

= 8

p(0) = 3 × (0) - 1

= 0 - 1

= -1

p(-2) = 3 × (-2) - 1

= -6 - 1

= -7

Prove that the point (4,-5),(1,1) and(-2,7) are collinear ( by distance formula)​

ANSWER:-DISTANCE formula is

rootover( x2-x1)^2+(y2-y1)^2.

Given points are A = (4,-5)

B = (1,1)

C = (-2,7).

Distance between A and B = Distance between B and C not equal Distance between C and A.

Therefore this three points are not collinear.

Use euclid's division algorithm to find the hcf of 136,170&255​

I HOPE IST helpful plz MAKE me brinslint I NEED brinslint plz make me brinslint have a great day

Euclid division lemma:-

a = bq + r

0 ≤ r < b

First,find the HCF of 255 and 170

» 255 = 170(1) + 85

170 = 85(2) + 0

HCF of 255 and 170 is 85

Now find the HCF of 136 and 85

» 136 = 85(1) + 51

85 = 51(1) + 34

51 = 34(1) + 17

34 = 17(2) + 0

HCF of 136 and 85 is 17

Therefore! HCF (136,170,255) = 17
