10th standard - samacheer kalvi - English - Memory Poem - "Life" - Henry Van Dyke

Life

Henry Van Dyke
(Watch Video ЁЯСЙЁЯСЙЁЯСЙ  click here ЁЯСИЁЯСИЁЯСИ ро╡ீроЯிропோро╡ாроХ рокாро░்роХ்роХ)

Let me but live my life from year to year, 
With forward face and unreluctant soul;
Not hurrying to, nor turning from the goal; 
Not mourning for the things that disappear 
In the dim past, nor holding back in fear 
From what the future veils; but with a whole And happy heart, that pays its toll 
To Youth and Age, and travels on with cheer.

So let the way wind up the hill or down, 
O'er rough or smooth, the journey will be joy: Still seeking what I sought when but a boy, New friendship, high adventure, and a crown, My heart will keep the courage of the quest, And hope the road's last turn will be the best.

6th standard - Samacheer kalvi - 3rd term - English - Memory Poem - " Indian Seasons" - Nisha Dyrene

Indian Seasons
(watch video ЁЯСЙЁЯСЙclick here ЁЯСИЁЯСИ ро╡ீроЯிропோро╡ாроХ рокாро░்роХ்роХ)


summer comes
in a blaze of heat 
with sunny smiles 
and dusty feet

Then seasons change 
to muddy roads 
monsoons and mangoes 
leapfrogs and toads

Spring is pretty 
but short and sweet
when you can smell the grass 
from your garden seat

Autumn is English
in red, yellow and brown 
Autumn is Indian 
Whenever leaves fall down"

________________

Question 1.
If n(A × B) = 6 and A = {1, 3} then n(B) is
(1) 1
(2) 2
(3) 3
(4) 6
Answer:
(3) 3

Hint:
If n(A × B) = 6
A = {1, 1}, n(A) = 2
n(B) = 3

Question 2.
A = {a, b,p}, B = {2, 3}, C = {p, q, r, s)
then n[(A ∪ C) × B] is ………….
(1) 8
(2) 20
(3) 12
(4) 16
Answer:
(3) 12

Hint: A ∪ C = [a, b, p] ∪ [p, q, r, s]
= [a, b, p, q, r, s]
n (A ∪ C) = 6
n(B) = 2
∴ n [(A ∪ C)] × B] = 6 × 2 = 12

Question 3.
If A = {1, 2}, B = {1, 2, 3, 4}, C = {5, 6} and D = {5, 6, 7, 8} then state which of the following statement is true.
(1) (A × C) ⊂ (B × D)
(2) (B × D) ⊂ (A × C)
(3) (A × B) ⊂ (A × D)
(4) (D × A) ⊂ (B × A)
Answer:
(1) (A × C) ⊂ (B × D)]

Hint:
A = {1, 2}, B = {1, 2, 3, 4},
C = {5, 6}, D ={5, 6, 7, 8}
A × C ={(1,5), (1,6), (2, 5), (2, 6)}
B × D = {(1, 5),(1, 6),(1, 7),(1, 8),(2, 5),(2, 6), (2, 7), (2, 8), (3, 5), (3, 6), (3, 7), (3, 8)}
∴ (A × C) ⊂ B × D it is true

Question 4.
If there are 1024 relations from a set A = {1, 2, 3, 4, 5} to a set B, then the number of elements in B is ………………….
(1) 3
(2) 2
(3) 4
(4) 8
Answer:
(2) 2

Hint: n(A) = 5
n(A × B) = 10
(consider 1024 as 10)
n(A) × n(B) = 10
5 × n(B) = 10
n(B) = 105 = 2
n(B) = 2

Question 5.
The range of the relation R = {(x, x2)|x is a prime number less than 13} is
(1) {2, 3, 5, 7}
(2) {2, 3, 5, 7, 11}
(3) {4, 9, 25, 49, 121}
(4) {1, 4, 9, 25, 49, 121}
Answer:
(3) {4, 9, 25, 49, 121}]

Hint:
R = {(x, x2)/x is a prime number < 13}
The squares of 2, 3, 5, 7, 11 are
{4, 9, 25, 49, 121}

Question 6.
If the ordered pairs (a + 2,4) and (5, 2a + 6) are equal then (a, b) is ………
(1) (2, -2)
(2) (5, 1)
(3) (2, 3)
(4) (3, -2)
Answer:
(4) (3, -2)

Hint:

The value of a = 3 and b = -2

Question 7.
Let n(A) = m and n(B) = n then the total number of non-empty relations that can be defined from A to B is
(1) mn
(2) nm
(3) 2mn – 1
(4) 2mn
Answer:
(3) 2mn - 1

Question 8.
If {(a, 8),(6, b)} represents an identity function, then the value of a and 6 are respectively
(1) (8,6)
(2) (8,8)
(3) (6,8)
(4) (6,6)
Answer:
(1) (8,6)

Hint:
 f = {{a, 8) (6, 6)}. In an identity function each one is the image of it self.
∴ a = 8, b = 6

Question 9.
Let A = {1, 2, 3, 4} and B = {4, 8, 9, 10}. A function f : A → B given by f = {(1, 4),(2, 8),(3, 9),(4, 10)} is a
(1) Many-one function
(2) Identity function
(3) One-to-one function
(4) Into function

Answer:
(3) One-to one function

Hint:

A = {1, 2, 3, 4), B = {4, 8, 9,10}
Question 10.
If f(x) = 2x^2 and g (x) = 1/3x, Then fog is
Answer:
(3) 2/9x^2

Queston 11.
If f: A → B is a bijective function and if n(B) = 7 , then n(A) is equal to …………..
(1) 7
(2) 49
(3) 1
(4) 14

Answer:
(1) 7

Hint:
n(B) = 7
Since it is a bijective function, the function is one – one and also it is onto.
n(A) = n(B)
∴ n(A) = 7

Question 12.
Let f and g be two functions given by f = {(0, 1), (2, 0), (3, -4), (4, 2), (5, 7)} g = {(0, 2), (1, 0), (2, 4), (-4, 2), (7, 0)} then the range of fog is
(1) {0, 2, 3, 4, 5}
(2) {-4, 1, 0, 2, 7}
(3) {1, 2, 3, 4, 5}
(4) {0, 1, 2}

Answer:
(4) {0, 1, 2}

Hint:
gof = g(f(x))
fog = f(g(x))
= {(0, 2),(1, 0),(2, 4),(-4, 2),(7, 0)}
Range of fog = {0, 1, 2}

Question 13.
Let f (x) = √1+x^2then ………………..
(1) f(xy) = f(x) f(y)
(2) f(xy) >= f(x).f(y)
(3) f(xy) <= f(x). f(y)

Answer:
(3) f(xy) <=f(x) . f(y)

(2) (2, -1)
(3) (-1, -2)
(4) (1, 2)

Answer:
(2) (2,-1)

Hint:
g(x) = ╬▒x + ╬▓
╬▒ = 2
╬▓ = -1
g(x) = 2x – 1
g(1) = 2(1) – 1 = 1
g(2) = 2(2) – 1 = 3
g(3) = 2(3) – 1 = 5
g(4) = 2(4) – 1 = 7

Question 15.
f(x) = (x + 1)3 – (x – 1)3 represents a function which is …………….
