5.A train 280 metres long is running at a speed of 42take to pass a man standing on a platform?6.A train 350 metres long crosses an electric pole in 28the train in km/hr. |
|
Answer» QUESTION 5) :- A train 280 metres LONG is RUNNING at a SPEED of 42km/h. How much time it take to pass a man standing on a platform ? Answer :- → Distance covered in crossing a man = Length of train = 280m . → Speed of train = 42 km/h = (42*5/18) = (35/3) m/s . → Time to cover = (Distance/Speed) = 280 ÷ (35/3) = 280 * (3/35) = 24 seconds (Ans.) ______________________Question 6) :- A train 350 metres long crosses an electric pole in 28seconds . Find the speed of train in km/hr. . ? Solution :- → Distance covered in crossing a Electric pole = Length of train = 350m . → Time to cross = 28 seconds . → Speed of Train = (Distance/Time) = (350/28) = (25/2) m/s = (25/2) * (18/5) = 45 km/h (Ans.) ____________________________ |

Proportional of a and cis b then prove that a, C,(b) If b is the mean proportional of a and c, prove that the mean proportional of a? +62 and b? + c?is ab + bc.(c) If b is the mean proportional of a and c, prove thatab + bc + ca= abc.a+b+c3 |
|
Answer» Answer:
please reply if you had understood . Step-by-step explanation:
Since, B is the mean PROPORTIONAL between a and C. So B2 = ac. L.H.S. = a2 – b2 + c2/a-2 – b-2 + c-2 = a2 – b2 + c2/1/a2 – 1/b2 + 1/c2 = (a2 – b2 + c2)/b2c2 – a2c2 + a2b2/a2b2c2 = a2b2c2 (a2 – b2 + c2)/b2c2 – b4 + a2b2 = b4 × b2(a2 – b2 + c2)/b2(c2 – b2 + a2) b4 = R.H.S. Hence proved. |

A sum of money Rs.2323 is divided among P:Q:R:S in the ratio x:4:5:6 and share of P is Rs.808. Then, find the fourth proportional to (x-6), (x-4) and (3x-1). |
Answer» Solution :-→ Share of P = {x/(x + 4 + 5 + 6)} * 2323 → 808 = {x/(x + 15)} * 2323 → 808(x + 15) = 2323x → 808x + 808*15 = 2323x → 2323x - 808x = 808*15 → 1515x = 808 * 15 → x = (808*15/1515) → x = 8 . Therefore, → (x - 6) = 8 - 6 = 2 → (x - 4) = 8 - 4 = 4 → (3x - 1) = 3*8 - 1 = 24 - 1 = 23 . __________Now, we have to find fourth proportional to 2,4 and 23. Let fourth proportional to 2,4 and 23 is x . Than, → 2 : 4 :: 23 : x → 2 * x = 4 * 23 → x = 2 * 23 → x = 46 (Ans.) Hence, 46 is the Answer for this problem. |

Prove that√p+√q where these are irrattional numbers |
|
Answer» Answer: LETS ASSUME that √p is rational, ⇒ √p = a/b ( where 'a' and 'b' are co primes, meaning they don't have any COMMON factors EXCEPT for 1) From squaring both sides, p = a²/b² ⇒pb² = a² ⇒ b² = a²/p Since 'p' divides a², it also divides 'a' meaning 'a' has a factor of p Let 'a' = pm (where m is a positive integer) ⇒ a² = p²m² Now, pb² = a² pb² = p²m² pb²/p²= m² b²/p =m² ∴ 'p' divides 'b' ⇒ 'b' also has a factor 'p' ∴ 'a' and 'b' are not co primes and our assumption was wrong ⇒ √p is irrational Similarly √q is irrational ∴⇒ √p + √q is irrational |
