Find the value of a, if the distance between the two points is: (4,-5), (-2,a) is √85 units?

Answer»

Answer:-

There Are Two values of 'a' is possible:-

  1. 2 and,
  2. - 12.

Explanation:-

Given:-

  • Two POINTS (4, -5) and (-2, a).

  • Distance between these two points is \tt\sqrt{85} Units.

To FIND:-

  • The possible values of a.

Formula USED:-

Distance Formula,

\gray{\bullet \boxed{ \green{ \bf d =  \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2}. }}}}

Where,

  • \tt x_2\:\:and\:\:x_2 Are the x coordinates of both the points.

  • \tt y_1\:\:and\:\:y_2 Are the y coordinates of both the points.

  • d = Distance between both the points.

So Here,

  • \tt x_2\:\:and\:\:x_2 Are -2 and 4 respectively.

  • \tt y_2\:\:and\:\:y_2 Are a and -5 respectively.

  • d = \sqrt{85} Units.

Now,

By PUTTING the above values in formula we get,

\\ \bf\mapsto \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2}} = d.  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \: \\  \\ \tt \mapsto \sqrt{ \bigg(( - 2) - (4) \bigg) {}^{2} +  \bigg( ( a)- ( - 5) \bigg) {}^{2}} =  \sqrt{85}  \: units. \\  \\ \tt\mapsto \sqrt{( - 2 - 4) {}^{2} + (a + 5) {}^{2}  }  =  \sqrt{85}  \: units. \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \tt\mapsto \sqrt{ (- 6) {}^{2} + ( {a}^{2} + 2 \times a \times 5 + 5 {}^{2} )  }  =  \sqrt{85}  \: units \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\\ \tt\mapsto\sqrt{ {a}^{2}  + 10a + 61}  =  \sqrt{85}  \: units.  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\ \tt\mapsto \bigg(\sqrt{ {a}^{2}  + 10a + 61} \bigg) {}^{2}  =  \bigg( \sqrt{85} \bigg) {}^{2} units. \\  \\  \bf(squaring \:  \: both \:  \: the \:  \: sides).

\\ \tt\mapsto {a}^{2}  + 10a + 61 =85. \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \tt\mapsto {a}^{2}  + 10a + 61 - 85 = 0. \\  \\ \tt\mapsto {a}^{2}  + 10a - 24 = 0. \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \tt\mapsto {a}^{2}  + (12 - 2)a - 24 = 0. \\  \\  \bf(splitting \:  \: middle \:  \: term) \\  \\ \tt\mapsto {a}^{2}  + 12a - 2a - 24 = 0. \\  \\ \tt\mapsto a(a + 12) - 2(a + 12) = 0. \\  \\ \tt\mapsto(a + 12)(a - 2) = 0. \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\\ \tt\mapsto either \: (a + 12) = 0 \:  \: or \:  \: (a - 2) = 0. \\  \\ \tt \red{\mapsto \:  \: \boxed{ \blue{ \bf  either \:  \: a =  - 12 \:  \:  \:  \: or \:  \:  \:  \: a = 2.}}}

Therefore The required values of a are -12 and 2.

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.

Answer»

GIVEN

α \:  , β \:  are \:  the \:  roots  \: of  \: ax² + bx + c = 0  \: where  \: a , b , c \:  \in \mathbb{Q}

TO PROVE

i] α + β is always rational

ii] α - β is always irrational

iii] αβ is always rational

iv] α , β are conjugate to each other

CONCEPT TO BE IMPLEMENTED

A general equation of quadratic equation is

a {x}^{2} +  bx + c = 0

Now ONE of the way to solve this equation is by SRIDHAR ACHARYYA formula

For any quadratic equation

a {x}^{2} +  bx + c = 0

The roots are given by

\displaystyle \: x =  \frac{ - b \pm \:  \sqrt{ {b}^{2} - 4ac } }{2a}

EVALUATION

Sridhar Acharya Formula for finding the roots of the quadratic equation ax² + bx + c = 0

The roots of the quadratic equation

ax² + bx + c = 0 is given by

\displaystyle \: x =  \frac{ - b \pm \:  \sqrt{ {b}^{2} - 4ac } }{2a}

Let

\displaystyle \:  \alpha \:  \:  =  \frac{ - b  +    \sqrt{ {b}^{2}  - 4ac} }{2a}

and

\displaystyle \:  \beta \:  =  \frac{ - b  - \:  \sqrt{ {b}^{2}  - 4ac} }{2a}

i)

\displaystyle \:  \alpha  +  \beta\:  \:

\displaystyle \:   =  \frac{ - b  +    \sqrt{ {b}^{2}  - 4ac} }{2a}  +    \frac{ - b   -     \sqrt{ {b}^{2}  - 4ac} }{2a}

\displaystyle \:   =  -  \frac{2b}{2a}

\displaystyle \:  =  -  \frac{b}{a}

Which is rational

So α + β is always rational

ii)

\displaystyle \:  \alpha  -  \beta\:  \:

\displaystyle \:  =  \frac{ - b  +    \sqrt{ {b}^{2}  - 4ac} }{2a}  - \frac{ - b   -     \sqrt{ {b}^{2}  - 4ac} }{2a}

\displaystyle \:  = \frac{ 2 \sqrt{ {b}^{2}  - 4ac} }{2a}

\displaystyle \:  = \frac{ \sqrt{ {b}^{2}  - 4ac} }{a}

Which is irrational

So α - β is always irrational

iii)

\displaystyle \:  \alpha   \beta\:  \:

\displaystyle \:   =  \frac{ - b  +    \sqrt{ {b}^{2}  - 4ac} }{2a}   \times \frac{ - b   -     \sqrt{ {b}^{2}  - 4ac} }{2a}

\displaystyle \:  =   \frac{ {b}^{2} - ( {b}^{2}  - 4 ac\: ) }{4 {a}^{2} }

\displaystyle \:  =   \frac{ {b}^{2} - {b}^{2}   +  4 ac\:  }{4 {a}^{2} }

\displaystyle \:  =   \frac{4ac}{4 {a}^{2} }

\displaystyle \:  =    \frac{c}{a}

Which is rational

So αβ is always rational

iv)

SINCE α & β are of the form

x +  \sqrt{y}  \:  \: and \:  \: x -   \sqrt{y}respectively

Also

\displaystyle \:  \alpha \beta \:  =  \frac{c}{a}

So α , β are conjugate to each other

To Find : n ज्ञात कीजिए  ​

Solution:

राम ने साल के पहले सप्ताह में ₹5 की बचत की

a = 5

फिर सप्ताह एक बचत में 1. 75 रूपों की वृध्दि कि

d = 1.75

nthसप्ताह में उसकी सप्ताहिक बचत 20. 75 रूपए हो जाती है

aₙ =a  + (n-1)d

=> 20.75  = 5  + (n-1)(1.75)

Prove that√p+√q where these are irrattional numbers​

Answer»

Answer:

\huge\bold\star\pink{Answer}\star

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
