The positive solutions of the equation ux + vy = w always lie in which quadrant?

Answer»

Step 1

It is given that the solution of the EQUATION is positive, it means the values of the X and y is positive.

Therefore, x>0 and y>0


Step 2

Since we KNOW that if the values of x and y in the first quadrant is positive, i.e. greater than 0 and

hence we can say that the positive solutions of the equation px + QY + r = 0 always LIE in first

quadrant as shown below.


thus they lie in the first Quadrant

A man distributed 236 toffees to children such that each child get as many toffees as there were children. Find the no. of children, if 11 toffees were left out after the distribution.

Answer»

Given total NUMBER of toffees DISTRIBUTED = 236.


Number of children's LEFT out = 11.


Number of children's left in = 236 - 11


= 225.



Given that Each child GET as many toffees as there were children.


= > \sqrt{225}


= > \sqrt{15^2}


= > 15.



Therefore, the number of children = 15.

Please solve this question step by step

Answer»

Given : <klux>X</klux> = 1 - \sqrt{<klux>2</klux>}


= > \frac{1}{x} = \frac{1}{1 - \sqrt{2}} * \frac{1 + \sqrt{2}}{1 + \sqrt{2}}


= > \frac{1 + \sqrt{2}}{1^2 - (\sqrt{2})^2}


= > \frac{1 + \sqrt{2}}{1 -  2}


= > \frac{1 + \sqrt{2}}{-1}


= > -1 - \sqrt{2}


Now,


= > x - \frac{1}{x} = 1 - \sqrt{2} - (-1 - \sqrt{2})


= > 2.


Therefore,


= > (x - 1/x)^3 = (2)^3


= 8.

43.

C is twice efficient as a and b is thrice time consume thanc.of a complete alone work in 12 days then find how many days all complete the work.

Answer»

C is twice EFFICIENT as A


efficiency is inversely proportional to time


A takes 12 days to complete so C will TAKE 6 days


And B takes thrice the time of C


So B takes 18 days


Now total work = LCM of 12, 6, 18 = 36


1 day work = 1/12 + 1/6 + 1/18 = (3+6+2) / 36 = 11/36


so whole work will be completed in 36/11 days = 3 3/11 days

Fill in the blanks (please answer the questions with separately)1)(2x-3y)³ = _________________2)(2x+Y-z)²=________________3)(3a+b)³=__________________

Answer»

(1)


(a - b)^3 = a^3 - b^3 - 3ab(a - b).


(2x - 3Y)^3 = (2x)^3 - (3y)^3 - 3(2x)(3y)(2x - 3y)


= 8x^3 - 27y^3 - 36x^2y + 54xy^2.




(2)


Given (2x + y - z)^2


= > (2x + y - z)(2x + y - z)


= > 4x^2 + 4xy - 4xz + y^2 - 2YZ + z^2.




(3)


(a + b)^3 = a^3 + b^3 + 3ab(a + b).


Given : (3a + b)^3


= > (3a)^3 + (b)^3 + 3(3a)(b)(3a + b)


= > 27a^3 + b^3 + 9ab(3a + b)


= > 27a^3 + b^3 + 27a^2b + 9ab^2.
