5.	Find the HCF of 392 and 732 by euclid's division lemma.
Answer» Answer: The DIVISOR at this stage, ie, 4 is the HCF of 732 and 393. Given : 732 and 393 To find : The HCF of 392 and 732 by EUCLID's Division Lemma = ? Step-by-step explanation: Clearly, 732 > 392 Applying the Euclid's division lemma to 732 and 392, we get 732 = 392 × 1 + 340 Since the remainder 340 ≠ 0, we apply the Euclid's division lemma to divisor 392 and remainder 340 to get 392 = 340 × 1 + 52 We consider the new divisor 340 and remainder 52 and apply the division lemma to get 340 = 52 × 6 + 28 We consider the new divisor 52 and remainder 28 and apply the division lemma to get 52 = 28 × 1 + 24 We consider the new divisor 28 and remainder 24 and apply the division lemma to get 28 = 24 × 1 + 4 We consider the new divisor 24 and remainder 4 and apply the division lemma to get 24 = 4 × 6 + 0 Now, the remainder at this stage is 0. So, the divisor at this stage, ie, 4 is the HCF of 732 and 393.

Find the HCF of 392 and 732 by euclid's division lemma.

Answer»

Answer:

The DIVISOR at this stage, ie, 4 is the HCF of 732 and 393.

Given :

732 and 393

To find :

The HCF of 392 and 732 by EUCLID's Division Lemma = ?

Step-by-step explanation:

Clearly, 732 > 392

Applying the Euclid's division lemma to 732 and 392, we get

732 = 392 × 1 + 340

Since the remainder 340 ≠ 0, we apply the Euclid's division lemma to divisor 392 and remainder 340 to get

392 = 340 × 1 + 52

We consider the new divisor 340 and remainder 52 and apply the division lemma to get

340 = 52 × 6 + 28

We consider the new divisor 52 and remainder 28 and apply the division lemma to get

52 = 28 × 1 + 24

We consider the new divisor 28 and remainder 24 and apply the division lemma to get

28 = 24 × 1 + 4

We consider the new divisor 24 and remainder 4 and apply the division lemma to get

24 = 4 × 6 + 0

Now, the remainder at this stage is 0.

So, the divisor at this stage, ie, 4 is the HCF of 732 and 393.

if the line (x-y+1) + k(y-2k+4) =0 makes equal intercepts on the axes . Then what is the value of k ?

Answer»

$\textbf{Given:}$

$\text{<klux>EQUATION</klux> of the <klux>LINE</klux> is (x-y+1)+k(y-2k+4)=0}$

$\textbf{To find:}$

$\text{The value of k}$

$\textbf{Solution:}$

$\text{Consider,}$

$(x-y+1)+k(y-2k+4)=0$

$x+(k-1)y-2k^2+4k+1=0$

$x+(k-1)y=2k^2-4k-1$

$\text{Divide both sides by $2k^2-4k-1$}$

$\dfrac{x}{2k^2-4k-1}+\dfrac{(k-1)y}{2k^2-4k-1}=1$

$\dfrac{x}{2k^2-4k-1}+\dfrac{y}{\dfrac{2k^2-4k-1}{k-1}}=1$

$\text{Comparing this with}$

$\bf\,\dfrac{x}{a}+\dfrac{y}{<klux>B</klux>}=1$

$\text{we get}$

$\text{x-<klux>INTERCEPT</klux>,}\;a=2k^2-4k-1$

$\text{y-intercept,}\;b=\dfrac{2k^2-4k-1}{k-1}$

$\text{But,}\;a=b$

$2k^2-4k-1=\dfrac{2k^2-4k-1}{k-1}$

$1=\dfrac{1}{k-1}$

$k-1=1$

$\implies\boxed{\bf\,k=2}$

9. The correct equation of motion is(a) + = + as(d) ms10. A car starting from rest accelerates uniformly to acquire a speed 20 km in 30 mindistance travelled by car in this time interval will be(a) 6 km(b) 5 km(c) 10 kmd 400 km11. The unit of velocity is :(a) km h'b) m min(c) km min!d) ms12. The unit of retardation is :(a) ms -(b) ms 2(cm13. 18 km h' is equal to :(a) 10 ms'(b) 5 ms(c) 18 ms(d) 18 ms14. A body when projected up with an initial velocity u goes to a height h in time t and thencomes back at the point of projection. The correct statement is:(a) The average velocity is 2 h/t(b) The acceleration is zero(c) The final velocity on reaching the point of projection is 2u(d) The displacement is zero15. If the displacement of an object is proportional to square of time, then the object moves with(a) Uniform velocity(b) Uniform acceleration(c) Increasing acceleration(d) Decreasing acceleration16. Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speedof 10 ms. It implies that the boy is:a At rest(b) Moving with no acceleration(c) In accelerated motion(d) Moving with uniform velocity17. Area under a vt graph represents a physical quantity which has the unit:(a) m(b) mto mº(d) ms!18. Slope of a velocity-time graph gives(a) The distance (b) The displacement (c) The acceleration (d) The speed19. A particle is moving in a circular path of radius r. The displacement after half a circle would befal Zero(b) ar(c) 2r(d) 2512:55 pm
