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

Triangle ABC has vertices A (1,1), B (3,2) and C (0,-2), It is dilated by a scale factor of 1/2 about the origin to create trian
Ghella [55]

Answer:

The length is 2.5 units

Step-by-step explanation:

Before we find the value of the length of the side, we need the measure of the coordinates after dilation

B’ = 1/2 B = 1/2(3,2) = (1.5, 1)

C’ = 1/2 C = 1/2( 0,-2) = (0,-1)

The measure of the length is the distance between the two points

Mathematically, that would be;

D = √(x2-x1)^2 + (y2-y1)^2

D = √(0-1.5)^2 + (-1-1)^2

D = √(2.25 + 4)

D = √6.25

D = 2.5 units

A submarine sits at -300 meters in relation to sea level. Then it descends 115 meters. What is it’s new position in relation to
Anna71 [15]

Answer:

A. -415m

Step-by-step explanation:

-300 meters is the starting point.

Then, the submarine goes 115m further below the surface, which can be represented as -115.

Add -300 and -115 and you get -415m.
