What values of c and d would make the following expression represent a real number? i(2 3i)(c di) c = 2, d = 3 c = –2, d = 3 c =

Olegator [25]

Complete question:

What values of c and d would make the following expression represent a real number? i(2 + 3i)(c + di)

choices: A)c = 2, d = 3 B)c = –2, d = 3 C)c = 3, d = –2 D)c = –3, d = –2

Option D is correct. The value of c and d for the expression to be real are -3 and -2 respectively

Given the expression

$i(2 + 3i)(c + di)$

Expand the expression

$=i(2 + 3i)(c + di)\\=(2i+3i^2)(c+di)\\=(2i+3(-1))(c+di)\\=(2i-3)(c+di)\\=2ic+2di^2-3c-3di\\=2ic-2d-3c-3di$

Collect the like terms

$=2ic-3di-2d-3c$

For the resulting function to be real, then the imaginary part must be zero i.e.

$2ic-3di=0\\2ci = 3di\\2c = 3d\\c=\frac{3d}{2}\\$

If d = -2, then;

$c=\frac{3(-2)}{2}\\c=\frac{-6}{2}\\c= -3$

Hence the value of c and d for the expression to be real are -3 and -2 respectively.

When faxing sensitive compartmented information.

laila [671]

In Cybersecurity, when faxing a sensitive compartmented information (SCI), the actions you should take include:

1. Mark the sensitive compartmented information (SCI) documents appropriately.

2. Use an approved sensitive compartmented information (SCI) fax machine.

A sensitive compartmented information (SCI) can be defined as a United States program that was established to segregate classified information concerning or derived from methods, analytical processes and intelligence sources, into distinctive compartments for added protection when disseminated or distributed.

Generally, the dissemination of information of all sensitive compartmented information (SCI) documents must be handled within formal access control systems and directives of the Director of National Intelligence.

Based on national intelligence, when faxing a sensitive compartmented information (SCI), the actions you should take include:
