If a, b, c, d, e are in continued proportion, prove that a^2+b^2+c^2+d^2,ab+bc+cd+de,b^2+c^2+d^2+e^2 |
|
Answer» (i) Since a, B, c, d are in continued proportion then a/b = b/c = c/d = k ⇒ a = bk, b = ck , c = dk ⇒ a = ck2 ⇒ a = dk3, b = dk2 and c = dk (ii) L.H.S. = (d2k6 + d2k4 + d2k2)(d2k4 + d2k2 + d2) = d2k2 (K4 + k2 + 1).d2 (k4 + k2 + 1) = d4k2(k4 + k2 + 1)2 R.H.S. = (ab + bc + cd)2 = (dk3.dk2 + dk2.dk + dk.d)2 = d4.k2(k4 + k2 + 1)2 L.H.S. = R.H.S. Hence proved. |

3x+4y=30,x+2y=12 by elimination method |
|
Answer» Answer: x=6; y=3 Step-by-step explanation: Given: 3x+4y = 30.........equation (1) x+ 2y = 12.............equation (2) In ELIMINATION METHOD, we need to manipulate the equations in such manner that one of the variables gets eliminated and only one variable remains. So multiplying equation (2) by 3 we get 3x + 6y = 36 Now subtracting the above equation from equation (1) we get- 3x + 4y - 3x - 6y = 30 - 36 or -2y = -6 or y = 3 Putting the VALUE of y in equation (1) , we get 3x + 4*3 = 30 or 3x = 30-12= 18 or x= 6 Hope you find this useful.

1 A body is moving with a velocity of 10 m/s. If it starts accelerating withthe rate of 2.5 ms? Find out its velocity after 10 s. |
Answer» <U>Given :To find :
FORMULA used :First equation of motion
( where u is initial velocity , a is acceleration , v is final velocity and t is time ) Calculation :Using first equation of motion → v = u + a t → v = (10) + (2.5) (10) → v = 10 + 25 → v = 35 ms⁻¹ Therefore, Velocity of body after 10 seconds will be 35 ms⁻¹.
