Hello,
1)
z=√3-i
==>ρ²=3+1=4==>ρ=2
arctg(√3/-1)=-60°
z=2∠-60°=2(cos(-60°)+i sin(-60°))
w=-2-2i
==>ρ²=4+4=8==>ρ=2√2
arctg(-2/-2)=45°
w=2√2∠45°=2√2(cos(45°)+i sin(45°))
2)
z²=(√3-i)²=3+1-2√3*i=4-2√3*i
3)w^4=(2√2∠45°)^4=(2√2)^4 ∠180° =-64+0i
You may use radian but i like more degree.
Answer:
should get 0.2 hope this helps you!
Step-by-step explanation:
Answer:
The hurricane traveled 260 miles per hour.
Step-by-step explanation:
Given,
Distance covered by hurricane = 130 miles
Then time = hours= hour
Distance=Speed*Time
Speed=
Speed=
Speed=260 miles per hour
So, the hurricane traveled 260 miles per hour
Answer:
non-linear it's parallel line
