Answer:

30°, 45° and 105°

Step-by-step explanation:

2 + 3 + 7 = 12 parts

180/12 = 15 degrees each part

First angle (2 parts)

2(15) = 30°

Second angle (3 parts)

3(15) = 45°

Third angle (7 parts)

7(15) = 105°

Hope this helps

Given f(x) = 2x² + 4 and g(x) = 3x – 1 ……<br> What is (fg)(x)? <br><br> Show your work.

Lelu [443]

Answer:

(fg)(x) = 6x³ - 2x² + 12x - 4

Step-by-step explanation:

( f g ) ( x ) = f ( x ) * g ( x )

f(x) = 2x² + 4

g(x) = 3x – 1

( f g ) ( x ) = (2x² + 4) (3x – 1)

= 6x³ - 2x² + 12x - 4

-4|x-11|=-16 solve for x in the equation

BigorU [14]

Answer:

x = 7 and 15

Step-by-step explanation:

Divide both sides by -4...

| x - 11 | = 4

because

| -4 | = 4 and

| 4 | = 4

x - 11 = -4 and x - 11 = 4

solve for x in both equations.

x = 7 and x = 15

Find the argument of the complex number z=1+iv3

elena-14-01-66 [18.8K]

Given:

The complex number is:

$z=1+i\sqrt{3}$

To find:

The argument of the given complex number.

Solution:

If a complex number is $z=x+iy$ , then the argument of the complex number is:

$\theta=\tan^{-1}\dfrac{y}{x}$

We have,

$z=1+i\sqrt{3}$

Here, $x=1$ and $y=\sqrt{3}$ . So, the argument of the given complex number is:

$\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}$

$\theta =\tan^{-1}\sqrt{3}$

$\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)$

$\theta =\dfrac{\pi}{3}$

Therefore, the argument of the given complex number is $\theta =\dfrac{\pi}{3}$ .

Joe was planning a business trip to Canada, so he went

nika2105 [10]

Answer:

2203.20 pesos

Step-by-step explanation:

Joe's original amount was $200

#We convert this amount to $CDN:

$\$1=1.02\$CDN\\\\=200\times 1.02\\\\=204\$CDN$

Joe now has to convert the Canadian dollars to Mexican pesos(at a rate of 10.8 pesos per $1 CDN):

$=204\times10.8\\\\=2203.2$

Hence, he gets a total of 2203.20 pesos in exchange for his Canadian dollars.
