Which, if any, of
Nadya [2.5K]

You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)

We can covert, using the following formulas:

Find r:

(x, y) --> (2, 2\sqrt{3})

r^2 = \sqrt{x^2 + y^2}

r^2 = \sqrt{2^2 + (2\sqrt{3})^2}

r = 4

Now, find our angle:

Use the inverse of tan

\tan^{-1} \frac{2}{2\sqrt{3}} = 30\deg

Turn 30 degrees to radian

\frac{\pi}{180} * 30 = \frac{1}{6}\pi

Answer = (4, \frac{1}{6}\pi) = C

I need to algebraically prove that a polynomial I created is true for a project.
natta225 [31]

The factors are

(x-y)(x-y)
or
(x-y)^2

Explanation:

We need to factor the trinomial
x^2-2xy+y^2

The factors of x^2 = (x)(x)
The factors of y^2 = (y)(y)

Since the second sign is positive we are adding the factors meaning the signs of the factors need to be the same. Since the first sign is negative both signs must be negative.

The factors are

(x-y)(x-y)
or
(x-y)^2

Check by FOIL
Firsts (x)(x) = x^2
Outers (x)(-y) = -xy
Inners (-y)(x) = -xy
Lasts (-y)(-y) = y^2
combine the middle terms
(-xy)+(-xy) = -2xy
