Answer:

a=8

Step-by-step explanation:

We are asked to solve this equation -90=-2(6a-3) . As here our variable is a , we will solve it for a. Let us do it step by step

1. Opening the brackets and distribution of -2 inside

-90=-12a+6

2. Subtracting 6 from both sides we get

-90-6=-12a+6-6

-96=-12a

3. Dividing both sides by 12 we get

$\frac{-96}{-12}=\frac{-12a}{-12}$

$a=8$

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:

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

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

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