17451.

Find the condition that zeroes of the polynomial ax2 + bx + c = 0 are reciprocal of each other.

Answer»

Answer:

let the ZEROS be x and y

Given x=1/y

product of zeros

xy=axc

y/y=axc

1=axc

a=c

Therefore the condition is a and c are equal

Make this sum fast please

Answer»

ANSWER:

$16 = {4}^{2}$

$({x}^{2} - 16) = ({x}^{2} - {4}^{2} )$

$({x}^{2} - {y}^{2} ) =( x + y)(x - y)$

$x = x$

$y = 4$

$( {x}^{2} - {4}^{2} ) = (x + 4)(x - 4)$

The external length, breadth and height of a closed rectangular wooden box are 20 cm, 12 cm and 6 cm respectively and thickness of wood is 0.5 cm. Find the volume of wood.

Answer»

QUESTION :-

➠ The external length, breadth and height of a closed rectangular wooden BOX are 20 cm, 12 cm and 6 cm respectively and THICKNESS of wood is 0.5 cm. Find the VOLUME of wood.

ANSWER :-

➠ Let

•external length of the closed box → L •external breadth of the closed box → B •external height of the closed box → H

so ,

L = 20 cm,
B = 12 cm,
H = 6 cm

➠ Let

•internal length of the closed box → l •internal breadth of the closed box → b •internal height of the closed box → h

so ,

l = [20 – (2 × 0.5)] cm 19 cm
b = [12 (2 × 0.5)] cm = 11 cm
h = [6 - (2 x 0.5)] cm = 5 cm

➠ External volume of the box

→ L × B x H

→ (20 × 12 × 6) cm³

→ 1440 cm³

➠ External volume of the box

→ l × b × h

→ (19 × 11 × 5) cm ³

→ 1045 ³

➠Volume of wood = External volume Internal volume

→ (1440 - 1045) cm ³

$→ 395 cm³$

Given that root 2 is irrational. Show that 5 + root 2 is irrational.

Answer»

Answer:

Given: root2 is irrational

Now,let US assume that 5 + root2 is rational

So,

5+root2 = a/b

root2 = a/b-5

Root2 = a-5b/b

This MEANS root 2 is rational.

But we KNOW that root2 is irrational.

So, our assumption was wrong.

Hence, 5+root2 is irrational.

17472.

Please give the right answer of this question and solve it with herons formula

Answer»

Step-by-step explanation:

In ∆ABD, AB=√12²+5²=13

so , AB =13

Area ∆ABD =1/2 × 12×5=30 SQ units

Perimeter of ∆ABC=A+B+C=15+14+13=42

semi-perimeter=21

Area of ∆ABC =√S(S-A)(S-B)(S-C)

=√21×(21-15)×(21-14)×(21-13)

=√21×6×7×8

=√7056

=84 sq units

Area of the shaded figure = 84-30

=54 sq units

Hence, the area of the shaded REGION is 54 sq units.

Answer» It has given that $\vec{u}=6\hat{i}+0\hat{j}-2\hat{k}$ and $\vec{v}=0\hat{i}+8\hat{j}+0\hat{k}$ To find : The cross product of $\vec{u}$ and $\vec{v}$ i.e., $\vec{u}\times\vec{v}$ solution : $\vec{u}\times\vec{v}=(6\hat{i}+0\hat{j}-2\hat{k})\times(0\hat{i}+8\hat{j}+0\hat{k})$ = (6i - 2k) × (8j ) = 6i × 8j - 2k × 8j = 48 k - 16(-i) = 48 k + 16I = 16i + 48k Therefore the cross product of $\vec{u}$ and $\vec{v}$ is (16, 0, 48). also read SIMILAR questions : RESULTANT of $\vec{P}$ and $\vec{Q}$ is $\vec{R}$ .

Let \vec{u} u ⃗ = (6,0,-2) and \vec{v} v ⃗ = (0,8,0). What is \vec{u} u ⃗ X \vec{v} v ⃗ ?

Answer»

It has given that $\vec{u}=6\hat{i}+0\hat{j}-2\hat{k}$ and $\vec{v}=0\hat{i}+8\hat{j}+0\hat{k}$

To find : The cross product of $\vec{u}$ and $\vec{v}$ i.e., $\vec{u}\times\vec{v}$

solution : $\vec{u}\times\vec{v}=(6\hat{i}+0\hat{j}-2\hat{k})\times(0\hat{i}+8\hat{j}+0\hat{k})$

= (6i - 2k) × (8j )

= 6i × 8j - 2k × 8j

= 48 k - 16(-i)

= 48 k + 16I

= 16i + 48k

Therefore the cross product of $\vec{u}$ and $\vec{v}$ is (16, 0, 48).

17491.	A fraction becomes 1/2 if 2 is added to its numerator . when 1 is subtracted from the denominatorand it becomes 1/3 .Find the fraction
Answer» ANSWER:- Let the fraction be x/y. Given: A fraction becomes 1/2 if 2 is added to numerator. → (x + 2)/y = 1/2 On cross multiplication we GET, → 2(x + 2) = y → 2x + 4 = y -- EQUATION (1) And, It becomes 1/3 if 1 is subtracted from denominator. → x/(y - 1) = 1/3 → 3x = y - 1 Substitute "y" value from equation (1). → 3x = 2x + 4 - 1 → 3x - 2x = 3 → x = 3 Substitute "x" value in equation (1). → y = 2(3) + 4 → y = 6 + 4 → y = 10 Hence, the required fraction x/y is 3/10.

A fraction becomes 1/2 if 2 is added to its numerator . when 1 is subtracted from the denominatorand it becomes 1/3 .Find the fraction

Answer»

ANSWER:-

Let the fraction be x/y.

Given:

A fraction becomes 1/2 if 2 is added to numerator.

→ (x + 2)/y = 1/2

On cross multiplication we GET,

→ 2(x + 2) = y

→ 2x + 4 = y -- EQUATION (1)

And,

It becomes 1/3 if 1 is subtracted from denominator.

→ x/(y - 1) = 1/3

→ 3x = y - 1

Substitute "y" value from equation (1).

→ 3x = 2x + 4 - 1

→ 3x - 2x = 3

→ x = 3

Substitute "x" value in equation (1).

→ y = 2(3) + 4

→ y = 6 + 4

→ y = 10

Hence, the required fraction x/y is 3/10.

Answer:

Step-by-step EXPLANATION:

a = bq+r ( Euclid's division LEMMA )

Substituting , we get ,

125 = 5q + r { This statement says that which number 'Q' multiplied with 5 gives 125 with an addition of remainder 'r' }

5*25 = 125

⇒

125 = 5(25) + 0
