If a+b+c=9 and ab+bc+ca=40,find a square +b sqaure+c square

Answers

Hi there !!

Given,

a + b + c = 9

ab + bc + ca = 40

To find : a² + b² + c²

The FOLLOWING expression matches to the algebraic identity

(a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ac or

(a + b + c)² = a² + b² + c² + 2( ab + bc + ac)

Thus,

(a + b + c)² = a² + b² + c² + 2(ab + bc + ac)

substituting the values,

we have,

9² = a² + b² + c² + 2( 40)

81 = a² + b² + c² + 80

Transposing 80 to LHS,

we have,

81 - 80 = a² + b² + c²

Thus,

a² + b² + c² = 1

The sum of three numbers whose ratios are 3 whole 1 by 3 ratio 4 whole 1 by 5 ratio 6 whole 1 by 8 is 4917 find the numbers.

Answer»

,hey buddy hope this finds u well ALSO mark me brainliest


10/3x+21/5x+49/8x=4917.........(1)
x[10/3+21/5+49/8]=4917
x[10*5*8+21*3*8+49*3*5]
= 4917*3*5*8
x[400+504+734]=4917*3*5*8
x[1639]=590040
x=590040/1639=360
x=360.
put the VALUE of x into equation (1) and we get,
10/3x=1200,
21/5x=1512,
49/8x=2205.
we get the three numbers are 1200, 1512, and 2205.

Simplify (x+3) (x-3) (x+5) (x-5) using suitable formulas

Answer»

Answer:

x² - 34X + 225

Step-by-step EXPLANATION:

(x+3) (x-3) (x+5) (x-5)

[(x+3)(x-3)] * [(x+5)(x-5)]

By using identity: (a+b)(a-b) = a² - b²

{ In both [(x+3)(x-3)] and [(x+5)(x-5)] }

[(x+3)(x-3)] * [(x+5)(x-5)] = (x² - 3²) * (x² - 5²)

                                      = (x² - 9) * (x² - 25)

Now, by using identity: (a + m)(a + N) = a² + (m+n)a + mn

{ On (x² - 9)(x² - 25) }

(x² - 9)(x² - 25) = x² + [-9 + (-25)]x + (-9)(-25)

                        = x² + (-34)x + 225

(x² - 9)(x² - 25) = x² - 34x + 225

Note: (*) sign represents here for multiplication.

Hope this helps...

Sum of the squares of two consecutive natural numbers is 313 find the natural number​

Answer»

\Large{\textbf{\underline{\underline{According\;to\;the\;Question}}}}

ASSUMPTION,

FIRST consecutive NUMBER be p

ALSO,

Second consecutive number be p + 1

Now,

Situation,

⇒ p² + (p + 1)² = 313

⇒ 2p² + 2p + 1 = 313

⇒ 2p² + 2p - 312 = 0 ...... (1)

Now,

Divide (1) by 2

⇒ p² + p - 156 = 0

⇒ p² + 13p - 12p - 156 = 0

⇒ p(p + 13) - 12(p + 13) = 0

⇒ (p + 13) (p - 12) = 0

⇒ p + 13 = 0

⇒ p = -13 (Not possible)

Also,

⇒ p - 12 = 0

⇒ p = 12

⇒ p = 12

Hence,

First number = p = 12

Second number = p + 1 = 12 + 1 = 13

One card is drawn from a well shuffled deck of 52 cards .Find the probability of getting*a king of red colour*a spade please answer this question please say correct answer ​

Answer»

Step-by-step explanation:

your answer is here

ANSWER

i) King of red colour can be hearts King or a diamond king.

So, the possibility is 2.

P(Red king)= 522

= 261

ii) A face card can be JACK, queen, king of any suite.

In this way we will get 3×4=12 face cards.

P(Face card)= 5212

= 133

iii) A red face card can be EITHER hearts or diamond king, jack or queen, which means there are 3×2=6

P(Red face card)= 526

= 263

IV) There is only one Jack of hearts.

P(Jack of hearts)= 521

v) There are 13 SPADES in total.

So, P(Spade)= 5213

= 41

vi) There is only one queen diamond.

Hence, P(Queen diamond)= 521

hi friend

Religion can never reform mankind because religion is slavery. It is far BETTER to be free, to leave the forts and barricades of fear, to stand erect and face the future with a smile. It is far better to give yourself sometimes to negligence, to drift with wave and tide, with the BLIND force of the world, to THINK and dream, to forget the chains and limitations of the breathing LIFE, to forget purpose and object, to lounge in the picture gallery of the brain, to feel once more the clasps and kisses of the past, to bring life's morning back, to see again the forms and faces of the dead, to paint fair pictures for the coming years, to forget all Gods, their promises and threats, to feel within your veins life's joyous stream and hear the martial music, the rhythmic beating of your fearless heart. And then to rouse yourself to do all useful things, to reach with thought and deed the ideal in your brain, to give your fancies wing, that they, like chemist bees, may find art's nectar in the weeds of common things, to look with trained and steady eyes for facts, to find the subtle threads that join the distant with the now, to increase knowledge, to take burdens from the weak, to develop the brain, to defend the right, to make a palace for the soul. This is real religion. This is real worship”
