Answer:
20
Step-by-step explanation:
the whole angle needs to be 180 degrees 180-100=80 80-20=60 20×3=60 60+20=80 80+100=180
It will be 48/52 because there are 4 kings so 52-4=48
Answer:
The circulation of the given vector is (5/2)x² + 7yz + 6yz + C
Step-by-step explanation:
Given that F = 5xi + 7zj + 6yk
The circulation of F is given as
Integral of F.dr
dr = idx + jdy + kdz
F.dr = (5xi + 7zj + 6yk).(idx + jdy + kdz)
= 5xdx + 7zdy + 6ydz
Integral of F.dr = Integral of (5xdx + 7zdy + 6ydz)
= (5/2)x² + 7yz + 6yz + C
Answer:
C: 4
Step-by-step explanation:
We can rearrange the numbers:

The complex conjugate of <span>7i</span><span> is </span><span>−7i </span>The complex conjugate of a number
z is a number with opposite imaginary part.
So if <span>z=a+bi</span> then conjugate is: <span><span>¯z</span>=a−bi</span> for any <span>a,b∈R</span>
We can note, that if we represent all complex numbers in coordinate system, then for any number: the number z and its conjugate <span>¯z</span> are symetrical according to "real part" axis.
