Question

Z=−24−12.77. What are the real and imaginary parts of zz?

A. Real part: −36.77 Imaginary part: 0
B. Real part: −36.77 , Imaginary part: −24
C. Real part: −12.77 Imaginary part: −24
D. Real part: −12.77 , Imaginary part: 0

Answer 1

The real part of zz is -36.77 and the imaginary part is -24.

Step-by-step explanation:

The real part of a complex number is the part that does not involve the imaginary unit, which is represented by the letter 'i'. In this case, the complex number is zz, which is equal to -24 - 12.77i. So the real part of zz is -24. The imaginary part of a complex number is the part that involves the imaginary unit 'i'. In this case, the imaginary part of zz is -12.77.

Therefore, the correct answer is B. Real part: -36.77, Imaginary part: -24.
