Answer:
y/4+8=22
y/4=22-8
y/4=14/1
y=56
Answer:
y = 3.5
Step-by-step explanation:
First, you do 14/4 which = 3.5
Hope this helps!
Write your answer in the form a + bi.
The sum of -2 + i and its complex conjugate is:
w = -4 + 0i
The complex conjugate of a number z = a + bi is:
z' = a - bi.
Then the complex conjugate of -2 + i is -2 - i.
The sum will give:
w = -2 + i + (-2 - i) = -4 + 0
Writing it in the wanted form we get:
w = -4 + 0i

Answer:
- 4
Step-by-step explanation:
The conjugate of - 2 + i is - 2 - i, thus
- 2 + i + (- 2) - i
= - 2 + i - 2 - i ← collect like terms
= - 4 ← in the form a + bi with b = 0
equation:
n=
2 - 2i
Answer:
a+ib=2sqrt2(cos7pi/4+isin7pi/4)
Step-by-step explanation:
a+ib=r (cos theta+isin theta)
r=sqrt a^2+b^2
r=sqrt (2)^2 +(-2)^2
r=2sqrt 2
theta=tan^-1(y/x) or (a/b)
theta= tan^-1(-2/2)
theta=-45 degrees
Now, I know that theta is in the fourth quadrant because cos (x-value) is positive. So, I am going to subtract my value from 360 degrees.
360-45= 315
theta=315
I can convert degrees to radians (if need be): 315 times pi/180= 7pi/4
Theta=7pi/4 r=2sqrt2
Substitute: a+ib=2sqrt2(cos7pi/4+isin7pi/4) this is radian format
or... a+ib=2sqrt2(cos 315+isin315) this is degree format
