The complex number is given as: 2-8i
So for conjugate, you just flip the sign of the imaginary part:
2+8i will be the answer
It’s b. :) hope this helps you
The circumference of a circle is equal to C=2πr
From the question, we have 615.44.
Assume that pi is equal to 3.14
Substitute and solve for r
615.44= 2(3.14)r
r= 615.44/ 6.28
r=98.4704
r=98
Therefore, the radius is about 98 units.
To check:
C=2πr
C=2 x 3.14 x 98
C=6.28 x98
C=615.44
Answer:
the constant of proportionality is 6.32
