Prove that √3+√5 is an irrational |
Answer» Let √3 + √5 be a RATIONAL number , say rthen √3 + √5 = rOn SQUARING both sides,➡(√3 + √5)² = r² ➡3 + 2 √15 + 5 = r² ➡8 + 2 √15 = r² ➡2 √15 = r2 - 8 ➡√15 = (r2 - 8) / 2 Now (r2 - 8) / 2 is a rational number and √15 is an irrational number .Since a rational number cannot be EQUAL to an irrational number . Our assumption that √3 + √5 is rational wrong . |

The production of TV sets in a factory increases uniformly by a fixed number every year . It produced 16000 sets in 6th year and 22600 in 9th year. 1. Find the production in first year.2.Find the production in 8th year.3. Find the production during first 3 years.4. In which year, the production is Rs. 29,200. |
|
Answer» ong>Step-by-step explanation: Solution : Let the production during first year be a and let d be the increase in production every year. Then, T6=16000⇒a+5d=16000…(i) andT9=22600⇒a+8d=22600...(ii) On SUBTRACTING (i) from (ii), we get 3d=6600⇒d=2200 Putting d = 2200 in (i), we get a+5×2200=16000⇒a+11000=16000 ⇒a=16000-11000=5000 Thus, a = 5000 and d = 2200. (i) Production during first year, a = 5000 (ii) Production during 8TH year is given by T8=(a+7d)=(5000+7×2200)=(5000+15400)=20400. (iii) Production during first 6 YEARS is given by S6= 6 2
{2a+5d}=3(2×5000+5×2200) =3(10000+11000)=63000 |

Find theẢ Principal Value of sin -¹A (1/2)1333he |
|
Answer» ONG>Answer: 2 x √ 1 − x 2 Step-by-step EXPLANATION: y = arcsin x , then x = y
sin ( 2 arcsin x ) = sin 2 y = 2 sin y cos y
cos 2 y + sin 2 y = 1
cos 2 y = 1 − x 2
⇒
cos y = √ 1 − x 2
∴ sin ( 2 arcsin x ) = 2 x √ 1 − x 2 |
