Answer:

Arc length of circle with circumference 18 and an arc with a 120° central angle is:

6

Step-by-step explanation:

The arc length of a circle is given by:

Here, circumference=18

i.e. 2πr=18

and

Arc length=

Hence, Arc length of circle with circumference 18 and an arc with a 120° central angle is:6

A set of equations is given below:

y=2x+6

y=2x+2

Solve y=2x+6 for y

Substitute 2x+6 for y in y=2x+2

y=2x+2

2x+6=2x+2

Add -2x to both sides

2x+6-2x= 2x+2-2x

6=2

Add -6 to both sides

6-6=2-6

0=-4

Let z =38 (cos(pi/8)+ i sin(pi/8)) and w = 2 (cos( pi/16 ) + i sin(pi/16))
mario62 [17]

Answer:

zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )

Step-by-step explanation:

Given

z =38 (cos(\frac{\pi}{8})+ i sin(\frac{\pi}{8}) and

w = 2 (cos(\frac{\pi}{16} ) + i sin(\frac{\pi}{16})

Required

Determine zw

Given that:

x = v_1(cos(a) + isin(a)) and y = v_2(cos(b) + isin(b))

x * y = (v_1 * v_2)*((cos(a+b) + isin(a+b))

So, we have:

zw=(38 * 2) * (cos(\frac{\pi}{8} + \frac{\pi}{16}) + isin(\frac{\pi}{8} + \frac{\pi}{16}))

zw=76 * (cos(\frac{2\pi + \pi}{16})+isin(\frac{2\pi + \pi}{16}))

zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )
