Simplify 21/5+-53/10+3/2

Answer»

ANSWER:

Step-by-step explanation:

21/5 - 53/10 + 3/2

=> 42/10 - 53/10 + 15/10 (see rules for addition in fractional no.s with different denominators)

=> (42/10 + 15/10) - 53/10 (according to BODMAS RULE, which is Brackets, multiplication( having 'of'), division, multiplication, addition, subtraction, in accordance with the preference of solving simplification having all those abbr. , brackets and numerical symbols)

=> 57/10 - 53/10

=> 4/10

=> 2/5 (ans.)

Step-by-step EXPLANATION:

QUADRATIC EQUATION :

x²-(sum of roots)x + PRODUCT of roots = 0

or, x²- (2/3-5)x+2/3×-5 = 0

or, x²- (-13/5)x - 10/3 = 0

or, x² + 13x/5 - 10/3 = 0

or, (15x²+39x - 50)/15 = 0

Answer» Step-by-step EXPLANATION: Solving RHS (sec theta + TAN theta )² = sec²theta + 2 × sec theta × tan theta + tan² theta = 1/cos² theta + 2× (1/COS theta )× (sin theta / cos theta ) + sin² theta / cos² theta = 1/cos²theta + 2SIN theta / cos²theta + sin²theta / cos²theta = (1+2sintheta + sin²theta )/cos²theta =( 1 + sintheta )²/(1 - sin²theta ) By using algebraic formulae , we get , (1+sintheta ) ( 1+sintheta ) / (1 - sintheta )(1+ sintheta) = (1+ sintheta )/ (1 - sin theta )

1556.

Proove that:- 1 + sin tita / 1 - sin tita = (sec tita + tan tita )²Please answer as soon as possible

Answer»

Step-by-step EXPLANATION:

Solving RHS

(sec theta + TAN theta )²

= sec²theta + 2 × sec theta × tan theta + tan² theta

= 1/cos² theta + 2× (1/COS theta )× (sin theta / cos theta ) + sin² theta / cos² theta

= 1/cos²theta + 2SIN theta / cos²theta + sin²theta / cos²theta

= (1+2sintheta + sin²theta )/cos²theta

=( 1 + sintheta )²/(1 - sin²theta )

By using algebraic formulae , we get ,

(1+sintheta ) ( 1+sintheta ) / (1 - sintheta )(1+ sintheta)

= (1+ sintheta )/ (1 - sin theta )

1562.	Essay on childhood of Guru teg bahadur ji (600-700) words
Answer» Answer: Guru Tegh BAHADUR was born on 1 April 1621 in Amritsar and was named Tyaga Mal at birth. His parents were Guru Hargobind and MATA Nanaki. Guru Hargobind was the sixth Sikh Guru. As a child, Guru Tegh Bahadur was trained in martial arts, swordsmanship and horse riding. But DESPITE being an able fighter alongside his father in different battles, he seemed to choose a path of renunciation and meditation. He was married to Gujari in 1633. In 1656, they moved to the village of Bakala where Tegh Bahadur would spend a lot of time in contemplation and prayers. Tegh Bahadur’s father had not chosen him as his successor as he felt that the SIKHS at that time needed a worldly leader and his son had chosen the path of renunciation. So, Guru Hargobind elected his grandson Guru Har Rai as his successor. After Har Rai’s death at the age of 31, his son Har Kishan became the seventh Guru at the age of five. Har Kishan, however, died of a disease at the age of 7 in 1664. After that, there was CONFUSION as to who would become the ninth Guru. Before his death, Guru Har Kishan had pronounced that the next Guru would be found in Bakala. This was followed by many ‘pretenders’ in Bakala each claiming to be the Guru.

Allen Annie travels at xm/s and ym/s respectively. If the distance covered by both of them is same, what is the ratio of time taken by Annie

Answer»

LET the distance covered by both be S.

Let the time TAKEN by ALLEN be t1 and time taken by ANNIE be t2.

Speed = Distance/ Time

Time = Distance/ Speed.

t1 = S/ x

t2 = S/ y

Ratio of time taken by Annie to time taken by Allen= t2/ t1

= (S/y) / (S/x)

Find any three rational numbers between 3/5&4/7

Answer»

${\huge{\mathcal{\boxed{\blue{answer}}}}}$

: Three RATIONAL numbers between -3/7 and -2/7 are -11/28, -10/28 and -9/28

Let's find the EQUIVALENT FRACTIONS of -3/7 and -2/7

Explanation:

We multiply numerator and DENOMINATOR by 4,

-3/7 = (- 3 × 4) / (7 × 4) = -12/28

-2/7 = (-2 × 4)/ (7 × 4) = -8/28

Now, the numbers between -12 and -8 are -11, -10, -9

Three rational numbers between -12/28 and -8/28 are -11/28 , -10/28 , -9/28.

Therefore, three rational numbers between -3/7 and -2/7 are -11/28, -10/28 and -9/28
