Answer:
-4
Step-by-step explanation:
[√2(cos(3π/4) + i sin(3π/4))]⁴
(√2)⁴ (cos(3π/4) + i sin(3π/4))⁴
4 (cos(3π/4) + i sin(3π/4))⁴
Using De Moivre's Theorem:
4 (cos(4 × 3π/4) + i sin(4 × 3π/4))
4 (cos(3π) + i sin(3π))
3π on the unit circle is the same as π:
4 (cos(π) + i sin(π))
4 (-1 + i (0))
-4
Answer:The answer is 130
Step-by-step explanation:
Answer: 970
Step-by-step explanation:
3,880 divided by 100= 38.8*25=970
C=2/5 with syptolis thereon so 2/5(C5/9) is the abswer for C (F-32)= hypoteticulos syptolis F-25/32(-32/35) this the answer for (F-32)
Answer:
Earns 56,500
Tax 56,500 × 10/100
=5,650
Invest = 50,850 × 50/100
= 25,425
Food = 25,425 × 30/100
=7,627.5
Shopping = 17,797.5 × 20/100
=3,559.5
Remaining = 14,237.5
