Present cost of bike = 40000

Given P = 40000, R = 15, n = 2

Cost after two years= P(1 - R/100)^n= 40000(1 - 15/100)^2 = 40000(1 - 3/20)^2 = 40000(17/20)^2 = 40000(.85*.85)= 40000(.7225) = 28900

Cost of bike after 2 years = Rs 28900

dist d =√(a-c)² + (b-d)²

applying it for this ques we have d=10 units10 =√(2 - 10)² + (-3-y)²squaring both sides100 = (-8)² + (9 + y² + 6y)100 = 64 +9 + y² + 6yy² + 6y - 27 = 0y² + 9y - 3y - 27 = 0y(y + 9) -3(y + 9) = 0(y-3)(y+9) = 0y=3 or y=-9

the semi perimeter of the triangle is 48mthe two sides are 24m,and 32mlet the third side be xtherefore, we know thatsemi perimeter=_24_+_32_+_x_ 2or, 48=_24_+_32_+_x_ 2=48×2=24+32+x=96=56+xtherefore,x=(96-56)=40m

rational is a right answer

Rational number is the correct

It is irrational number

√44121 rational number

it is rational because it is square root of 21.

It is a rational number

its rational.... root of 441 is 21

441is square of 21 which is irrational number

It's rational number because the square root of 441is 21 Then, 21×21=441

it is rational because root 441= 21 which is a rational number

rational number is correct

√441 = 21 it is rational number because it is written in the form of p/q.

it is not rational it is irrational is the correct answer h

root441 is rational not irrational

rational number is a correct answer

it's irrational is the best correct answer

Answer is Rational number

√441=21That's whyit is a rational number

it is rational number

21×21=441 so it is a rational number

It is a rational number

√441=21 so that is rational number

21 is the square root of 441 it is an rational number

it is a rational number because square root for 441 is 21 and 21 is a rational number

Rational is correct answer

root 441 is rational because it's value is 21

√ 441 is rational because it occurs in the form of p/q

it is not irrational no. it is rational no.

root 441is a rational number because it is the perfect square of 21

root 441 is rational number not irrational number

the square of 21 is 441 , yes this is a rational number.

root 441 is a rational number

It is a rational number as it is the square root of 21.

Your correct answer is-½-⅓-¼-⅔-¾-⅝

correct answer is -1/2, -1/3, -1/4 , -2/3, -3/4, -5/8

Let us assume that√5 is a rational number.we know that the rational numbers are in the form of p/q form where p,q are integers.so,√5 = p/q p =√5qwe know that 'p' is a rational number. so√5 q must be rational since it equals to pbut it doesnt occurs with√5 since its not an integertherefore, p =/=√5qthis contradicts the fact that√5 is an irrational numberhence our assumption is wrong and√5 is an irrational number.

45=3*3*5hence √45=3√5 hence irrational

√45=√3*3*5=3√5hence,√45 is an irrational number

=> x^3 + x^2 - 2x -3 - 5 = (x-2)(x^2+ax+b)=> x^3 + x^2 - 2x - 8 = (x-2)(x^2+ax+b)

At x = 2, x^3 + x^2 - 2x - 8 = 0=> (x - 2) is a factor of x^3 + x^2 - 2x - 8;

Dividing x^3 + x^2 - 2x - 8 by (x-2), we get ---(x-2)(x^2+3x+4) = (x-2)(x^2+ax+b)

=> x^2+3x+4 = x^2+ax+b

Comparing the co-efficients, we get

a = 3 , b = 4 -------------- Ans

x^3 + x^2 - 2x - 3 -------- where ^ represents raise to the power.

=> x^3 + x^2 - 2x -3 - 5 = (x-2)(x^2+ax+b)=> x^3 + x^2 - 2x - 8 = (x-2)(x^2+ax+b)

At x = 2, x^3 + x^2 - 2x - 8 = 0=> (x - 2) is a factor of x^3 + x^2 - 2x - 8;

Dividing x^3 + x^2 - 2x - 8 by (x-2), we get ---(x-2)(x^2+3x+4) = (x-2)(x^2+ax+b)

=> x^2+3x+4 = x^2+ax+b

Comparing the co-efficients, we get

a = 3 , b = 4

Given:root2 is irrationalNow,let us assume that 5 +3root2 is rationalSo,5+3root2 = a/b3root2 = a/b-5 =a-5b/bRoot2 = a-5b/3b

But we know that root2 is irrationalSo, our assumption was wrong.Hence 5+3root2 is irrational.

Let the width of the rectangle be xan length of the rectangle will be 3xGiven,length of its diagonal is 6√10 cmso by Pythagoras theoremx^2 +(3x)^2 =(8√10)^2x^2+9x^2= 64010x^2=640x^2=64x=8

So breadth of the rectangle = 8cmlength of the rectangle= 3×8cm=24cmSo,Perimeter of the rectangle = 2(8+24)cm= 2×32cm=64cmHence perimeter of rectangle is 64 cm

Ratios of Complementary angles ,

Two angles are said to be Complementary , if their sum is equal

to 90°.

As you know that ,

Cot ( 90 - x ) = tan x

According to the problem given,

Tan 2A = cot ( A - 18 )

Cot ( 90 - 2A ) = cot ( A - 18 )

Remove the cot both sides

we get ,

90 - 2A = A - 18

-2A - A = - 18 - 90

- 3A = - 108

A = ( - 108 ) / ( - 3 )

A = 36°
