Explanation of Solution
Given information:
The given statement is:
“What is the complex conjugate of a complex number”
When the real part and the imaginary part of a complex number is equal in magnitude, but has opposite signs, then it is called the complex conjugate of a complex number.
d.

d.

Explanation of Solution
Given information:
The given statement is:
“How do you add, subtract, multiply and divide complex numbers.
In addition of complex numbers, the real parts and the imaginary parts are added separately.
In subtraction of complex numbers, the real parts and the imaginary parts are subtracted separately.
In multiplication of complex numbers, multiply like binomials using
In division of complex numbers, multiply the numerator and denominator by the complex conjugate of the denominator.

- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall?
