Solve the equation and get the answeer.

Aseem Mahajan 6 years, 2 months ago

1500×250/x -125 = x/2 => x²/2 = 375000 -125x

Aseem Mahajan 6 years, 2 months ago

Then put y =1500/x (as xy =1500)

Aseem Mahajan 6 years, 2 months ago

250y-x/2=125 not 0

Aseem Mahajan 6 years, 2 months ago

Wsit last 3 steps are wrong !! I sm so sorry!

Aseem Mahajan 6 years, 2 months ago

After solving u get x = 500√3 , so the ysual speed u let as x is 500√3 kmph

Aseem Mahajan 6 years, 2 months ago

Put y = 1500/x , (as u get before xy=1500)

Aseem Mahajan 6 years, 2 months ago

Then u get xy -x/2 +250 y -125 =xy Cancel xy , u get 250y -x/2=0

Aseem Mahajan 6 years, 2 months ago

Remember to take time in hours

Aseem Mahajan 6 years, 2 months ago

So , (x+250)(y-1/2) = xy

Aseem Mahajan 6 years, 2 months ago

Fhe speed is increased and time decreased , but the distance will be same , i e, xy

Aseem Mahajan 6 years, 2 months ago

Then the distance = xy = 1500 km

Aseem Mahajan 6 years, 2 months ago

Let the speed of aeroplane be x and normal time to cover the distance be y

Discriminant = b²-4ac

Aadya Singh ? 6 years, 2 months ago

x + 1/3 - 3 = 0
=> 3x-8 = 0
D= b^2 - 4ac
3^2+ 4×0×8
=> 9

Considering AZ = ZB, that means {tex}A Z^{2}=Z B^{2}{/tex}

{tex}(x-5)^{2}+(y-1)^{2}=(x+1)^{2}+(y-5)^{2}{/tex}

Squaring both the sides we get the factors and then simplifying them we get:

{tex}x^{2}+25-10 x+y^{2}+1-2 y=x^{2}+1+2 x+y^{2}+25-10 y{/tex}

12x = 8y

3x = 2y  

Hence proved

{tex}Distance\: from\\ \:the \:point \:P(3,2)\: and\\ \:the \:origin\\=5{/tex}

Step-by-step explanation:

{tex}\boxed{Distance\: from\\ \:the \:point \:(x,y)\: and\\ \:the \:origin\: is\: \sqrt{x^{2}+y^{2}}}{/tex}

{tex}Distance\: from\\ \:the \:point \:P(3,2)=(x,y)\: and\\ \:the \:origin\\= \sqrt{3^{2}+2^{2}}\\=\sqrt{9+4}\\=\sqrt{13}\\{/tex}

Therefore,

{tex}Distance\: from\\ \:the \:point \:P(3,2)\: and\\ \:the \:origin\\=\sqrt{13}{/tex}

It is given that, difference of two natural numbers is 5

Let the x, (x+5) are two natural numbers.

Reciprocals of the numbers are

x and 1/(x+5)

According to the problem given,

{tex}\frac{1}{x}-\frac{1}{x+5}=\frac{1}{10}{/tex}

{tex}\implies \frac{x+5-x}{x(x+5)}=\frac{1}{10}{/tex}

{tex}\implies \frac{x}{x^{2}+5x}=\frac{1}{5}{/tex}

Do the cross multiplication, we get

{tex}\implies 50=x^{2}+5x{/tex}

=> x²+5x-50=0

Splitting the middle term, we get

=> x²+10x-5x-50=0

=> x(x+10)-5(x+10)=0

=>(x+10)(x-5)=0

=> x+10 = 0 Or x-5=0

=> x = -10 Or x = 5

But the two numbers are natural numbers.

x = 5

Therefore,

Required two natural numbers are,

x = 5

and

x+5 = 5+5 = 10

See if we construct a circle and draw a triangle taking diameter as one of its side . Then its side become 2R ( diameter=R*2). Now ar of triangle=1/2*base*height. Here height is Radius i.e. 'R' so area =1/2*2R*R=R^2

Given that sin theta + 2 cos theta=1 Cos theta = 1 - sin theta by 2. (-1) Now we need to prove that 2 sin theta - cos theta=2. (-2) Now put the value of equation 1 in eq 2 We have 2 sin theta -(1 - sin theta by 2)=2 4 sin theta - 1 + sin theta by 2=2 4 sin theta + sin theta - 1 = 4 Sin theta =1. Put the value of sin theta in 1 equation Cos theta=1-1 by 2 Cos theta=0 Put the value in 2 equation 2*1-0=2 2=2 Hence proved
