Answer»

Step-by-step explanation:

we USE the PROPERTY i.e, ANGLES on the same ARC are equal.

from the above figure,

angle ABD = X and angle ACD = x , as both angles are in the same arc ABD .

&

angle CAB = y angle CDB = y , as both agles are in the same arc CAB .

so,

angle ABD = angle ACD = x

Answer»

Step-by-step explanation:

2.Since product of two odd number is odd

therefore, 5×7×11 is odd number

similarly 13×17 is an odd number

We KNOW, sum of two odd number is even.

Therefore,(5×7×11)+(13×17)= even number

we know, 2 is only even prime number and remaining all even number are composite.

Hence,(5×7×11) + (13×17) is a composite number.

3. here ,420>272

therefore 420= 272 × 1 + 148

272= 148 × 1 + 124

148= 124 × 1 + 24

124= 24 × 5 + 4

24= 4 × 6 + 0

since remainder is 0, thus the HCF is 4.

5.Let the two numbers be a and b.

Let the value of a be 207.

Given: HCF = 23 and LCM = 1449

We know, a × b = HCF × LCM

⇒ 207× b = 23 × 1449

⇒ ∴ b = (23 ×1449)/207

= 33327/207

= 161

Hence, the other number b is 161.

6.According to Euclid’s Division Lemma

Let take a as any positive integer and b = 9.

Then using Euclid’s algorithm we get a = 9q + r here r is remainder and value of Q is more than or equal to 0 and r = 0, 1, 2, 3, 4, 5 , 6 , 7 , 8, because 0 ≤r < b and the value of b is 9

Sp possible forms will 9q, 9q+1, 9q+2,9q+3,9q+4,9q+5,9q+6,9q+7 and 9q+8

to get the cube of these values use the formula

(a+b)³ = a³ + 3a²b+ 3ab² + b³

In this formula value of a is always 9q

So plug the value we get

(9q+b)³ = 729q³ + 243q²b + 27qb² + b³

Now divide by 9 we get quotient = 81q³ + 27q²b + 3qb² and remainder is b³

So we have to consider the value of b³

b = 0 we get 9m+0 = 9m

b = 1 then 1³ = 1 so we get 9m +1

b = 2 then 2³ = 8 so we get 9m + 8

b = 3 then 3³ = 27 and it is divisible by 9 so we get 9m

b = 4 then 4³ =64 divide by 9 we get 1 as remainder so we get 9m +1

b=5 then 5³=125 divide by 9 we get 8 as remainder so we get 9m+8

b=6 then 6³=216 divide by 9 no remainder there so we get 9m

b=7 then 7³ = 343 divide by 9 we get 1 as remainder so we get 9m+1

b=8 then 8³ = 512 divide by 9 we get 8 as remainder so we get 9m+8

So all values are in form of 9m , 9m+1 or 9m+8.

6.Let's suppose √2 is a rational number. Then we can write it √2 = a/b where a, b are whole numbers, b not zero.

We additionally assume that this a/b is simplified to lowest terms, since that can obviously be done with any fraction. Notice that in order for a/b to be in simplest terms, both of a and b cannot be even. One or both must be odd. Otherwise, we could simplify a/b further.

From the equality √2 = a/b it follows that 2 = A2/b2, or a2 = 2 · b2. So the square of a is an even number since it is two times something.

From this we know that a itself is also an even number. Why? Because it can't be odd; if a itself was odd, then a · a would be odd too. Odd number times odd number is always odd. Check it if you don't believe me!

Okay, if a itself is an even number, then a is 2 times some other whole number. In symbols, a = 2k where k is this other number. We don't need to know what k is; it won't matter. Soon comes the contradiction.

If we substitute a = 2k into the original equation 2 = a2/b2, this is what we get:

2 = (2k)2/b2

2 = 4k2/b2

2*b2 = 4k2

b2 = 2k2

This means that b2 is even, from which follows again that b itself is even. And that is a contradiction!!!

WHY is that a contradiction? Because we started the whole process assuming that a/b was simplified to lowest terms, and now it turns out that a and b both would be even. We ended at a contradiction; thus our original assumption (that √2 is rational) is not correct. Therefore √2 cannot be rational.

10.Let take a as any positive integer and b = 3.

Then using Euclid’s algorithm we get a = 3Q + r

here r is remainder and value of q is more than or equal to 0 and r = 0, 1, 2 because 0 < r < b and the value of b is 3 So our possible values will 3q+0 , 3q+1 and 3q+2

Now find the square of values

Use the formula (a+b)² = a² + 2AB +b² to open the square bracket

(3q)² = 9q² if we divide by 3 we get no remainder

we can write it as 3*(3q²) so it is in form of 3m here m = 3q²

(3q+1)² = (3q)² + 2*3q*1 + 1²

=9q² + 6q +1 now divide by 3 we get 1 remainder

so we can write it as 3(3q² + 2q) +1 so we can write it in form of 3m+1 and value of m is 3q² + 2q here

(3q+2)² = (3q)² + 2*3q*2 + 2²

=9q² + 12q +4 now divide by 3 we get 1 remainder

so we can write it as 3(3q² + 4q +1) +1 so we can write it in form of 3m +1 and value of m will 3q² + 4q +1

Square of any positive integer is either of the form 3m or 3m + 1 for some integer m.

or

let ' a' be any positive integer and b = 3.

we know, a = bq + r , 0 < r< b.

now, a = 3q + r , 0

the possibilities of remainder = 0,1 or 2

Case I - a = 3q

a2 = 9q2

= 3 x ( 3q2)

= 3m (where m = 3q2)

Case II - a = 3q +1

a2 = ( 3q +1 )2

= 9q2 + 6q +1

= 3 (3q2 +2q ) + 1

= 3m +1 (where m = 3q2 + 2q )

Case III - a = 3q + 2

a2 = (3q +2 )2

= 9q2 + 12q + 4

= 9q2 +12q + 3 + 1

= 3 (3q2 + 4q + 1 ) + 1

= 3m + 1 where m = 3q2 + 4q + 1)

From all the above cases it is clear that square of any positive integer ( as in this case a2 ) is either of the form 3m or 3m +1.

Hope it helps,

After some days of consumptionat that rate, 300 soldiers were transferred to anothergarrison and the balance food lasted for 25 days forthe remaining soldiers. If the rate of consumption ofthe remaining soldiers was 3.0 kg/dayl soldier, afterhow many days from the start, were the soldierstransferred?​

Answer»

Answer:

10 days

Step-by-step explanation:

INITIAL CONSUMPTION per day=900*2.5=2250 kg

Total amount of food =2250*30=67500 kg

after few days remaining soldier=900-300=600

total food remaining for 25 days with NEW consumption RATE= 600*3*25=45000 kg

in initial days food consumed=67500-45000=22500 kg

Answer is 450 km

Since distance travelled by PLANE is 1/3 of total journey then distance travelled by plane= 1/3×1800=600

Therefore distance travelled by TRAIN will be 5/3 × x= 5/3x

Differentiate the following functions with respect to x from first principles :(i) √x​

Answer»

ANSWER:

\displaystyle \boxed{{<klux>F</klux>'(x)=\frac{1}{2\sqrt{x}}}}

Step-by-step explanation:

Given :

f ( x ) = √ x

We have to DIFF. w.r.t. x

We have first PRINCIPLE of derivative .

If y = f ( x )

Then :

\displaystyle{f'(x)= \lim_{h \to 0}\frac{f(x+h)-f(x)}{h} }

= > f ( x + h ) = ( √ x + h )

\displaystyle{f'(x)= \lim_{h \to 0}\frac{\sqrt{x+h}-\sqrt{x}}{h} }

Now rationalize it we get :

\displaystyle{f'(x)= \lim_{h \to 0}\frac{\sqrt{x+h}-\sqrt{x}}{h} \times\frac{\sqrt{x+h}+\sqrt{x}}{\sqrt{x+h}+\sqrt{x}} }\\\\\\\displaystyle{f'(x)= \lim_{h \to 0}\frac{x+h-x}{h(\sqrt{x+h}+\sqrt{x})} }\\\\\\\displaystyle{f'(x)= \lim_{h \to 0}\frac{1}{(\sqrt{x+h}+\sqrt{x})} }

Putting h = 0

\displaystyle{f'(x)=\frac{1}{(\sqrt{x+0}+\sqrt{x})}}\\\\\\\displaystyle{f'(x)=\frac{1}{\sqrt{x}+\sqrt{x}} }\\\\\\\displaystyle{f'(x)=\frac{1}{2\sqrt{x}}}

Hence we get answer.
