Quizplus · Accepted Answer

The plot of the complex number -5+9i is located in the second quadrant of the complex plane with the real part being negative and the imaginary part being positive. The absolute value of a complex number is the distance from the origin to the point representing the complex number on the complex plane. Using the Pythagorean theorem, we have:
|-5+9i| = sqrt((-5)^2 + 9^2) = sqrt(106) = 10.29563014...
The closest option to this value is C: 11eacce6_1f55_4e63_9f49_d58f5ecd9cfa_TB7896_00, which represents 10.29563014... in hexadecimal format.
