(a + b - c)^2 is equal to

Answer»

ANSWER:

$(a + b - c)^{<klux>2</klux>}$ = $a^{2}+b^{2}+c^{2}+2ab-2bc-2ac$

Step-by-step explanation:

IDENTITY: (x+y+z)^2= $x^{2}$ + $y^{2} +z^{2}$ +2xy+2yz+2xz

Here, x=a, y=b, z=-c

Applying the identity,

=> $a^{2}+b^{2}+c^{2}+ 2(a)(b) + 2(b)(-c) + 2(a)(-c)$

latika bought a teapot for ₹240 and a set of cups for ₹400 . she sold the teapot ata profit of 8% and a cups at a loss of 8% . find the amount received by her on selling the teapot and set of cups

Answer»

Step-by-step explanation:

CP of teapot = 240ru

CP of set of cups = 400 RU

SP INCREASE % OF TEAPOT = 8%

SP DECREASE % OF SET OF CUPS = 8%

SP OF TEAPOT = BY UNITARY SYSTEM

1%=2.4 RU
8%. = 2.4*8 = 16+3.2 = 19.2RU
240+19.2 = 259.2 RU

SP OF CUP SET = BY UNITARY SYSTEM

1% = 4RU
8% = 32RU
400 - 32 = 368 RU

19.	If 3 Subtract from 5 times a number, the resultis 42. find The number
Answer» ANSWER:- The Required Number is 9. Explanation:- Given:- If 3 is subtracted from a number the result would be equal to 42. To FIND:- The Number. So, Let the Number be x. Therefore ATQ:- ↦ (5 × Number) - 3 = 42. ↦ (5 × x) - 3 = 42. ↦ 5x - 3 = 42. ↦ 5x = 42 + 3. ↦ 5x = 45. ↦ x = 45/5. ↦ x = 9. Therefore the Number is x which is equal to 9. More Related Information:- The equation having only ONE VARIABLE in it i.e. unknown value is called equation in one variable. Transportation method is the most common method to find out the value of unknown variable in such equations. In transportation method all known values are transported to one SIDE (Mostly Right Side i.e. RHS) and unknown values to another side (Mostly Left side i.e. LHS). During this transportation (+) become (-) and vise-versa, (×) becomes (÷) and vise-versa.

If 3 Subtract from 5 times a number, the resultis 42. find The number

Answer»

Explanation:-

Given:-

If 3 is subtracted from a number the result would be equal to 42.

To FIND:-

The Number.

So,

Let the Number be x.

Therefore ATQ:-

↦ (5 × Number) - 3 = 42.

↦ (5 × x) - 3 = 42.

↦ 5x - 3 = 42.

↦ 5x = 42 + 3.

↦ 5x = 45.

↦ x = 45/5.

↦ x = 9.

Therefore the Number is x which is equal to 9.

More Related Information:-

The equation having only ONE VARIABLE in it i.e. unknown value is called equation in one variable.

Transportation method is the most common method to find out the value of unknown variable in such equations.

In transportation method all known values are transported to one SIDE (Mostly Right Side i.e. RHS) and unknown values to another side (Mostly Left side i.e. LHS).

During this transportation (+) become (-) and vise-versa, (×) becomes (÷) and vise-versa.

38.	A man throws ball with the same speed vertically upwards one after the other at an interval of 2 seconds. What should be the speed of the throw so that more than two balls are in the sky at any time ? (Given g = 9.8m/s2 )
Answer» A man THROWS ball with the same speed VERTICALLY upwards one after the other at an interval of 2 SECONDS. What should be the speed of the throw so that more than two balls are in the sky at any time ? (GIVEN g=9.8m/s 2 ) ANSWER The correct option is A. We have t=2s When the ball is thrown upward the final velocity BECOME zero. Therefore, v=u+at 0=u−gt Here, g is acceleration due to gravity u=gt =9.8×2=19.6 m/s Thus, when he throws a ball with a minimum speed of 19.6m/s in a time interval of 2s. Then two balls can be in the air simultaneously.

Answer»

A man THROWS ball with the same speed VERTICALLY upwards one after the other at an interval of 2 SECONDS. What should be the speed of the throw so that more than two balls are in the sky at any time ? (GIVEN g=9.8m/s

2

)

ANSWER

The correct option is A.

We have t=2s

When the ball is thrown upward the final velocity BECOME zero.

Therefore,

v=u+at

0=u−gt

Here, g is acceleration due to gravity

u=gt

=9.8×2=19.6 m/s

Thus, when he throws a ball with a minimum speed of 19.6m/s in a time interval of 2s.

Then two balls can be in the air simultaneously.

The sum of first n terms of an AP is 13n2 - 21n , find its 10th term.anybody help pls!

Answer»

Step-by-step EXPLANATION:

Sn=1/2(3n^2+7n)

S1=1/2(3+7)=5

S2=1/2(3*4+7*2)=26/2=13

We KNOW

S1=a1=5

S2=a1+a2=13

S2-s1=a1+a2-a1

13-5=a2

a2=8

We know d=a2-a1

d=8-5=3

nth term of AP =an=5+(n-1)3

an= 2+3n

Therefore 20th term =

a20= 2+3(20)=62

Hence 20th term of AP is 62
