Which of the following is a third root of the given complex number? 27(cos(pi/5)+isin(pi/5))
Digiron [165]
<span>The third root of the given complex number 27(cos(pi/5)+isin(pi/5)) is <span>3(cos(pi/15)+i sin(pi/15)) 

</span>The solution would be like this for this specific problem:</span>   <span>2^5 = 32 so you need a 2 out front the 5th root of cos(x) + i sin(x) is cos(x/5) + i sin(x/5). Additionally, 5 roots are located at even intervals around the circle. They are spaced every 2 pi/5 or 6 pi/15 radians. </span>   <span>Roots are located at pi/15, pi/15+ 10pi/15 = 11 pi/15 and pi/15+ 20pi/15 = 21 pi/15 (or 7 pi /5 ).</span>

PLEASE HELP ASAP!! WILL GIVE BRAINLIEST
andrew11 [14]

Step-by-step explanation:

12) y = 4 + 7x

x = 3,-1

y = 4 + 7(3) = 25

13) y = x - 11

x = 72,

y = 72 - 11 = 61

14) y = 6x - 5

y = 6(-4) - 5 = -29

y = -11 (x = -1)

y = -5 (x = 0)

y = 13 (x = 3)

15) y = x + 1, each relation is a function

16) An = 22 + (n-1)11

A(2) = 22 + 1(11) = 33

A(5) = 22 + 4(11) = 66
