We have to find the equation of a circle with center (0,0). The circle touches the line 5x - 12y = 52. So the line is a tangent. The radius of the circle is the distance from (0,0) to the line 5x -...

• Math
We have to find the sum 1/[1+x/(y+z)]+1/[1+y/(z+x)]+1/[1+z/(x+y)] 1/[1+x/(y+z)]+1/[1+y/(z+x)]+1/[1+z/(x+y)] => (y + z)/(x + y + z) + (z + x)/(x + y + x) + (x + y)/(x + y + z) => (y + z + z +...

• Math
It is given that 18 added to x gives y => 18 + x = y Also, 18 multiplied by 4x gives y^2 => 18*4x = y^2 Now substituting y = 18 + x in 18*4x = y^2 => 18*4x = (18 + x)^2 => 72x = 18^2 +...

We have to solve 2x^4 - 11x^3 + 23x^2 - 19x + 5 = 0 2x^4 - 11x^3 + 23x^2 - 19x + 5 = 0 => 2x^4 - 3x^3 - 8x^3 + 12x^2 + 10x^2 + x^2 - 15x - 4x + 5 = 0 => 2x^4 - 3x^3 + x^2 - 8x^3+ 12x^2 - 4x +...

• Math
The value of lim_(x->0)(sqrt(1+x) - 1)/(3*sqrt(1+x) - 1) can be found by substituting x with 1. Doing so gives: (sqrt(0+1) - 1)/(3*sqrt(0+1) - 1) =>(1 - 1)/(3 - 1) =>  0/2 =>...

• Math
An odd function is one where f(-x) = -f(x). Here it is given that both f(x) and g(x) are odd functions. This means f(-x) = -f(x) and g(-x) = -g(x) fog(x) = f(g(x)) fog(-x) = => f(g(-x)) as g(-x)...
