Answer»

Answer:

√441 is a RATIONAL number

√27 is not rational

Step-by-step explanation:

441 is a rational number because it can be expressed as the quotient of two integers: 441÷ 1

Because there is a contradiction, the ASSUMPTION (1) that √2 is a rational number must be false. This means that √2 is not a rational number. That is, √2 is irrational.

If u subtract 1/2 from a number multiply 1/2 from it u get 1/8 solve

Answer»

ANSWER:

Let the number to be identified be x

As per the GIVEN condition

If we subtract 1/2 from a number and multiply the result by 1/2, we get 1/8.

So the EQUATION becomes

(1/2)(x – 1/2) = (1/8)

=(x – 1/2) = (1/4)

=4x – 2 = 1

=4x = 3

Hence x = 3/4

Therefore 3/4 is the number from which if we subtract 1/2 from a number and multiply the result by 1/2, we get 1/8.

If a:b=2:3 and b:c=4:5, find a:b:c.Give me the solution by explaining and give me a picture​

Answer»

ANSWER:=9:12:15:17

Step-by-step explanation: There are two ways of solving this question.

firstly,

given A:B=3:4

B:C=8:10

C:D=15:17

now, we ll find A,B,C,D respectively and then calculate the ratio

A=3x8x15 =360

now for calculating B we ll take B’s SHARE in A:B i.e. 4 instead of 3 and rest remains the same

B=4*8*15=480

similarly for c

C=4*10*15=600

and similarly in D’s share we ll take 4,10&17

D=4*10*17=680

so A:B:C:D=9:12:15:17 (DIVIDING all by 4)

thats the answer …this is simple ratio and proportion logic and will help in each variety of these questions.

second way is a SHORT cut way and it’ll SAVE a lot of time.

we have

A:B=3:4

B:C=8:10

C:D=15:17

now , we know in A:B ….A’s share is a multiple of 3 (generally written 3k)

say A=3k so, B’s share will be 4/3 of A’s share …i.e. B=4k

similarly C’s share will be 10/8 of B’s share…i.e. C=5k

and D’s share will be 17/15 of C’s share(5k) i.e…D=17/3k

multilplying complete by 3 we will get A=9k ;B=12k ;C=15k ;D=17k

so ratio A:B:C:D=9:12:15:17

if x sin ^3 theta +y cos^3 theta =sin theta cos theta and x sin theta =y cos theta ,then show that x^2 + y^2 =1

Answer»

Answer:

 

\large \text{$x^2+y^2=1$ \ proved}

Step-by-step EXPLANATION:

Given :

\large \text{$x \ sin^3\theta+y \ cos^3\theta=sin \theta. cos \theta$ and $x \ sin \theta=y \ cos\theta$}

We have prove

\large \text{$ x^2+y^2 =1$}

We KNOW that

\large \text{$tan=\dfrac{sin}{cos} $}

So we have

\large \text{ $x \ sin \theta=y \ cos\theta$}}\\\\\\\large \text{$tan \theta=\dfrac{y}{x} \ ...( i)$}

We ALSO have

\large \text{$x \ sin^3\theta+y \ cos^3\theta=sin \theta. cos \theta$}

Now divide it by cos^3 \theta we get

\large \text{$x \ \dfrac{sin^3\theta}{cos^3 \theta} +y \ \dfrac{cos^3\theta}{cos^3 \theta} =\dfrac{sin \theta. cos \theta}{cos^3 \theta} $}\\\\\\\large \text{$x \ tan^3 \theta + y = \dfrac{tan \theta}{cos \theta} $}

Now put VALUE of tan \theta=\dfrac{y}{x}

\large \text{$x \ (\dfrac{y}{x})^{3} \theta + y = \dfrac{y\sqrt{x^2+y^2} }{x\times x}$}}\\\\\\\large \text{Here we directly write $cos \theta=\sqrt{1+tan^2 \theta} $}\\\\\\\large \text{$y^3+x^2y=y\sqrt{x^2+y^2}$}\\\\\\\large \text{$x^2+y^2=\sqrt{x^2+y^2}$}\\\\\\\large \text{$1=\sqrt{x^2+y^2}$}\\\\\\\large \text{$x^2+y^2=1$}

One step it write directly you can see in picture.

Hence proved.
