Answer:
(-1,5) (3, 1/125)
Step-by-step explanation:
I used desmos to graph the equation then the points attached you will see the screenshot so you can be sure. The points are the same color as the circle on the left side of the point. Hope this helps!
Step-by-step explanation:
<DBA=180 since it is a straight line
<HBA=73
mHG=73
<span>use De Moivre's Theorem:
⁵√[243(cos 260° + i sin 260°)] = [243(cos 260° + i sin 260°)]^(1/5)
= 243^(1/5) (cos (260 / 5)° + i sin (260 / 5)°)
= 3 (cos 52° + i sin 52°)
z1 = 3 (cos 52° + i sin 52°) ←← so that's the first root
there are 5 roots so the angle between each root is 360/5 = 72°
then the other four roots are:
z2 = 3 (cos (52 + 72)° + i sin (52+ 72)°) = 3 (cos 124° + i sin 124°)
z3 = 3 (cos (124 + 72)° + i sin (124 + 72)°) = 3 (cos 196° + i sin 196°)
z4 = 3 (cos (196 + 72)² + i sin (196 + 72)°) = 3 (cos 268° + i sin 268°)
z5 = 3 (cos (268 + 72)° + i sin (268 + 72)°) = 3 (cos 340° + i sin 340°) </span>

Answer:
0.0332
Step-by-step explanation:
Min put too many zeros in front of 33.2. 33.2 with 3 zeros in front is 0.0332
