Question 3:An army contingent of 616 members is to march behind an army bandof 32 members in a parade. The two groups are to march in the samenumber of columns. What is the maximum number of columns inwhich they can march?​

Answer»

Answer:

the answer is 8

Step-by-step explanation:

To get the maximum number COLUMN here we always find HCF and for minimum number we find LCM

So can use Euclid’s algorithm to find the HCF.

Here 616> 32 so always divide greater number with smaller one

When we divide 616 by 32 we get QUOTIENT 19 and remainder 8

So we can write it as

616 = 32 X 19 + 8

Now divide 32 by 8 we get quotient 4 and no remainder

So we can write it as

32 = 8 x 4 + 0

As there are no remainder so our HCF will 8

So that maximum number of COLUMNS in which they can march is 8.

Can a number 4^n, n being a natural number, end with the digit 5? Give reason.​

Answer»

Answer:

no,it will not end with 5

Step-by-step EXPLANATION:

first check with what all can 4^n end

u can see that 4^1=4       4^2=16          4^3=64          4^4=256

                      4^5=1024  4^6=4096

so after two terms the ending number is repeating this is called cyclicity

we can see that 4^n where n is odd ENDS with 4 and where n is EVEN ends with 6

if n is 0 of couurse u know that it ends with 1

therefore it will not end with 5

If d1 and d2 is the diagonal of a rhombus then find side of the rhombus

Answer»

Heya MATE!!!

we are given that D1 and D2 DIAGONAL of rhombus.. we need to find its side.

we know that parallelograms on same base and between same parallels have equal areas.

so AREA of square = equal to area of rhombus

{s}^{2}  =  \frac{1}{2} d1 \times d2

so..

s =  \sqrt{ \frac{d1 \times d2}{2} }

if alpha, beta are the roots of the quadratic equation ax^2+bx+c=0 find a quadratic equation whose roots are alpha^2+beta^2 and aloha^-2+beta^-2​

Answer»

Answer:

a²c²x² - ( b^2 - 2ac )( a^2 + c^2 )x + ( b^2 - 2ac )^2 = 0

Step-by-step explanation:

Eq. is ax^2 + bx + c = 0    ⇒ x^2 - (-b/a)x + (c/a) = 0.

Quadratic equation written in the form of x^2 - Sx + P = 0 represent S as sum of roots and P as the product of their roots.

So, here if α and β are roots.

S = α + β = - b / a  

P = αβ = c / a

Therefore,

α^2 + β^2 = (α+β)² - 2αβ

    = ( - b / a )^2 - 2( c / a )

    = b^2 / a^2 - 2c / a

    = ( b^2 - 2ac ) / a^2

1 / α^2 + 1 / β^2

= ( α^2 + β^2 ) / ( αβ )^2

= {(b^2 - 2ac)/a^2}/{(c/a)^2}

= ( b^2 - 2ac ) / c^2

Here, we are asked for the equation with roots ( b^2 - 2ac ) / a^2 and ( b^2 - 2ac ) / c^2.

 So, if that equation is x^2 - Kx + L = 0. So, K is the sum of roots and L is the product of roots.

This means :

K = ( b^2 - 2ac ) / a^2 + ( b^2 - 2ac ) / c^2

K = ( b^2 - 2ac )( a^2 + c^2 ) / ( ac )^2

 And,

L = ( b^2 - 2ac )/a^2 * ( b^2 - 2ac )/c^2

L = ( b^2 - 2ac )^2 / ( ac )^2

HENCE the REQUIRED equation is :

 x^2 - x( b^2 - 2ac )( a^2 + c^2 )/(ac)^2 + ( b^2 - 2ac )^2/(ac)^2 = 0

a²c²x² - ( b^2 - 2ac )( a^2 + c^2 )x + ( b^2 - 2ac )^2 = 0

Hence the required equation is a²c²x² - ( b^2 - 2ac )( a^2 + c^2 )x + ( b^2 - 2ac )^2 = 0.

I am trying to solve for 2001 to the power of 2.

Answer»

Answer:

Step-by-step EXPLANATION:

(2001^2)

we will use identity for it ,

(2000+1)^2

we know,

(a+b)^2 = a^2 + 2ab + b^2

i.e.

(2000+1)^2 = (2000)^2 + 2(2000)(1) + (1)^2

that is,

4000000 + 4000 + 1

= 4004001
