PRECALC QUESTION! Convert the polar representation of this complex number into its standard form: z = 2(cos 11pi/6+ i sin 11pi/6

Tanzania [10]

$\bf z=2\left[ cos\left( \frac{11\pi }{6} \right) + i\ sin\left( \frac{11\pi }{6} \right) \right]\qquad 
\begin{cases}
r=2\\
\theta=\frac{11\pi }{6}\\
-----\\
a=x=rcos(\theta)\\
b=y=rsin(\theta)
\end{cases}\implies a+bi
\\\\\\
2cos\left( \frac{11\pi }{6} \right)+2sin\left( \frac{11\pi }{6} \right)\ i\implies 2\cdot \cfrac{\sqrt{3}}{2}+2\cdot \cfrac{-1}{2}\ i\implies \sqrt{3}-1i
\\\\\\
\boxed{\sqrt{3}-i}$

What is the GCF of 2x4 and 4x2<br> a) 2x^2. B) 2x^4. C) 4x^2

Zinaida [17]

Answer:

$a)\ \ \ 2x^2$

Step-by-step explanation:

-Greatest common factor is defined as the greatest positive that divides a set of whole numbers evenly and without a remainder.

-Given the set $2x^4\ \ and \ \ 4x^2$

we notice, that the GCF can't be an integer with the power of x greater than 2:

$=>\frac{2x^4}{2x^2}=x^2\\\\=>\frac{4x^2}{2x^2}=2\\\\GCF= 2x^2$

Since, there's no other positive integer than can evenly divide the set of quotients, the GCF is $2x^2$

2.When I walked into King Soopers yesterday, I noticed that the Colorado Rockies t-shirts had a sign reading “25% off sale!”. If

daser333 [38]

Given:

The discount is 25%.

The selling price of the shirt after the sale is $20.99.

To find:

The selling price of the shirt before the sl;e

Explanation:

Let the old price be x.

The equation can be framed as follows,

$\begin{gathered} (\frac{100-25}{100})\times x=20.99 \\ \frac{75}{100}\times x=20.99 \\ x=20.99\times\frac{100}{75} \\ x=27.986 \\ x\approx27.99 \end{gathered}$

Final answer:

The selling price of the shirt before the sale is $27.99.
