3. D. 3√2+3√6i, -3√2-3√6i
4. A. cos60°+i sin60°, cos180°+i sin180°, cos300°+i sin300°
5. D. 2√3(cos π/6+i sin π/6), 2√3(cos 7π/6+i sin 7π/6)
Answer:
in order from least to greatest:
-1.6, -1.4, -0.9, 0.25, 0.6
Step-by-step explanation:
Convert each numeral into its mixed number decimal fraction equivalent:
-1.4 = -1.4
-8/5 = -1.6
0.6 = 0.6
-0.9 = -0.9
1/4 = 0.25
Now arrange these in order from least to greatest:
-1.6, -1.4, -0.9, 0.25, 0.6
