SIZIF [17.4K]

Answer:

P + Q = 1

Step-by-step explanation:

Given: \frac{1+\sqrt{3} }{1-\sqrt{3} }  = P - \sqrt{Q}

This is a question on surd, so we need to rationalize the denominator to have;

\frac{1+\sqrt{3} }{1-\sqrt{3} }  * \frac{1+\sqrt{3} }{1+\sqrt{3} } = \frac{1+\sqrt{3}+\sqrt{3}  + 3}{1+\sqrt{3}-\sqrt{3} -3 }

   = \frac{4+ 2\sqrt{3} }{1-3}

   = \frac{4+2\sqrt{3} }{-2}

   = -2 - \sqrt{3}

Thus,

-2 - \sqrt{3} = P - \sqrt{Q}

⇒ P = -2 and Q = 3

Therefore, the value of P + Q = -2 + 3

                                                 = 1

Thus,

P + Q = 1

Answer:

The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.
