Litlle helped here;plz plz plz answer asap

Answer»

Answer:

11X - 7Y -6 = 0

Step-by-step explanation:

Let (5,7)=(X1,Y1) ; (-2,-4)=(X2,Y2)

Now, the equation in std form is

X-X1/X1-X2 = Y-Y1/Y1-Y2

X-5 / (5+2) = Y-7 (7+4)

X-5/7 = Y-7/11

11 x (X-5) = 7 x (Y-7)

11X - 55 = 7Y - 49

11X - 7Y - 6 = 0

To prove = 2√3 is an irrational number.

We shall prove this by the method of CONTRADICTION .

so let us ASSUME to the contrary that 2√3 is a RATIONAL number =r

2√3=r

√3=r/2

Now we know that √3 is irrational number.

SO, r/2 has to be irrational to make the EQUATION true .

This is a contradiction to our assumption . Thus our assumption is wrong .

13.	The sum of the digits of a two digit number is 10 and the digit at units place is 2/3rd of thedigit at tens place. Find the number.
Answer» GIVEN : The sum of the digits of a two digit number is 10 and the digit at units place is 2/3rd of the digit at tens place. To Find : The required number = ? Solution : Let the ten's digit of two digit number be x and ONE's digit be y. The required number = 10x + y In the question it is given that,The sum of the digits of a two digit number is 10. So, mathematically it can be expressed as : x + y = 10 [Equation (i)] It is also given that,the digit at units place is 2/3rd of the digit at tens place, mathematically it can be expressed as : y = ⅔ x [Equation (ii)] Now,plug in the value of y = ⅔ x from equation (ii) to equation (i) : → x + ⅔ x = 10 → (2x + 3X)/3 = 10 → 5x = 10 × 3 → 5x = 30 → x = 30 ÷ 5 → x = 6 Hence,the ten's digit of two digit number is 6. Now,substitute the value of x = 6 in equation (ii) : → y = ⅔ x → y = ⅔ × 6 → y = 2 × 2 → y = 4 Hence,the one's digit of two digit number is 4. ★ Finding the required number : → Required number = 10x + y → Required number = 10 × 6 + 4 → Required number = 60 + 4 → Required number = 64 Hence,the required two digit number is 64.

The sum of the digits of a two digit number is 10 and the digit at units place is 2/3rd of thedigit at tens place. Find the number.

Answer»

GIVEN :

The sum of the digits of a two digit number is 10 and the digit at units place is 2/3rd of the digit at tens place.

To Find :

The required number = ?

Solution :

Let the ten's digit of two digit number be x and ONE's digit be y.

The required number = 10x + y

In the question it is given that,The sum of the digits of a two digit number is 10. So, mathematically it can be expressed as :

x + y = 10 [Equation (i)]

It is also given that,the digit at units place is 2/3rd of the digit at tens place, mathematically it can be expressed as :

y = ⅔ x [Equation (ii)]

Now,plug in the value of y = ⅔ x from equation (ii) to equation (i) :

→ x + ⅔ x = 10

→ (2x + 3X)/3 = 10

→ 5x = 10 × 3

→ 5x = 30

→ x = 30 ÷ 5

→ x = 6

Hence,the ten's digit of two digit number is 6.

Now,substitute the value of x = 6 in equation (ii) :

→ y = ⅔ x

→ y = ⅔ × 6

→ y = 2 × 2

→ y = 4

Hence,the one's digit of two digit number is 4.

★ Finding the required number :

→ Required number = 10x + y

→ Required number = 10 × 6 + 4

→ Required number = 60 + 4

→ Required number = 64

Hence,the required two digit number is 64.

Check which of the following are solutions of an equation x+2y=4(1).(√2,-3√2)

Answer»

Answer:

( X, y ) = ( √2, - 3√2 )

Here,

x = √2

y = 3√2

x + 2y = 4

√2 + 2 ( 3√2 ) = 4

√2 + 6√2 = 4

48.	To verify the Thales theorem by method of paper foldings cutting and pasting.
Answer» Answer: To verify the Pythagoras theorem by METHOD of Paper Folding, Cutting and Pasting THEORY:- Pythagoras theorem:- It states that in a right angled triangle, the square of the largest side (Hypotenuse) is equal to the SUM of the squares of the other two sides(Perpendicular and the BASE). PRE-REQUISITE KNOWLEDGE:- Area of a Square Construction of Parallel lines and Perpendicular bisectors Construction of a Right triangle MATERIALS REQUIRED:- Coloured Paper, A pair of Scissors, Geometry box, Sketch Pens, Fevicol PROCEDURE:- 1) Cut out a right angled triangle ABC, with sides AC=8cm, AB=10cm, BC=6cm. 2) Cut 3 squares of dimensions 6cm x 6cm, 8cm x 8cm and 10cm x 10cm. 3) Place these squares on the sides of the triangle ABC corresponding to the sides of the square. 4) Now join the the diagonals of the square placed on the perpendicular or the base, say perpendicular. 5) THROUGHT the intersection POINT of the diagonals draw a line parallel to the base of the Hypotenuse AB of triangle ABC. 6) Now draw perpendicular bisector of the line segment drawn inside the square . Clearly the square is now divided into 4 parts by the former and the latter lines. 7) Now place these 4 quadrilaterals(parts) on the square of dimension corresponding to the hypotenuse such that all the right angles of the quadrilateral coincide with the 4 corners of the large square. 8) Now place the left out square in the middle space left. OBSERVATION:- we observe that the squares corresponding to the perpendicular and base of the triangle exactly fit over the square corresponding to the hypotenuse. RESULT:- Hence, we conclude that the area of the bigger square is equal to the sum of areas of two smaller squares. Hence, Square of the hypotenuse is equal to the sum of the squares of the other 2 sides of the right angled triangle. Hence, Pythagoras theorem is verified.

To verify the Thales theorem by method of paper foldings cutting and pasting.

Answer»

Answer:

To verify the Pythagoras theorem by METHOD of Paper Folding, Cutting and Pasting

THEORY:-

Pythagoras theorem:- It states that in a right angled triangle, the square of the largest side (Hypotenuse) is equal to the SUM of the squares of the other two sides(Perpendicular and the BASE).

PRE-REQUISITE KNOWLEDGE:-

Area of a Square

Construction of Parallel lines and Perpendicular bisectors

Construction of a Right triangle

MATERIALS REQUIRED:-

Coloured Paper, A pair of Scissors, Geometry box, Sketch Pens, Fevicol

PROCEDURE:-

1) Cut out a right angled triangle ABC, with sides AC=8cm, AB=10cm, BC=6cm.

2) Cut 3 squares of dimensions 6cm x 6cm, 8cm x 8cm and 10cm x 10cm.

3) Place these squares on the sides of the triangle ABC corresponding to the sides of the square.

4) Now join the the diagonals of the square placed on the perpendicular or the base, say perpendicular.

5) THROUGHT the intersection POINT of the diagonals draw a line parallel to the base of the Hypotenuse AB of triangle ABC.

6) Now draw perpendicular bisector of the line segment drawn inside the square . Clearly the square is now divided into 4 parts by the former and the latter lines.

7) Now place these 4 quadrilaterals(parts) on the square of dimension corresponding to the hypotenuse such that all the right angles of the quadrilateral coincide with the 4 corners of the large square.

8) Now place the left out square in the middle space left.

OBSERVATION:-

we observe that the squares corresponding to the perpendicular and base of the triangle exactly fit over the square corresponding to the hypotenuse.

RESULT:-

Hence, we conclude that the area of the bigger square is equal to the sum of areas of two smaller squares. Hence, Square of the hypotenuse is equal to the sum of the squares of the other 2 sides of the right angled triangle.

Hence, Pythagoras theorem is verified.

Step-by-step explanation:

I hope it helps you dear ❣❣☺☺❤❤
