Answer:
C
Step-by-step explanation:
<em>You will cover halfway up each wall. Since the total height of the wall is 8 feet, you will cover half of that, which is 4 feet. </em>
Length is 12 feet and full length will be covered.
So area covered in 1 wall is sq. ft.
There are 4 walls, so total area to be covered is sq. ft.
Each panel board is 4 feet by 8 feet, so 1 panel board's area is sq. ft.
So number of panel boards required to cover 192 sq. ft. with 32 sq. ft. boards is
So we need 6 panels. Answer choice C is right.

Answer:
The imaginary part is 0
Step-by-step explanation:
The number given is:
First, we can expand this power using the binomial theorem:
After that, we can apply De Moivre's theorem to expand each summand:
The final step is to find the common factor of i in the last expansion. Now:
The last part is to multiply these factors and extract the imaginary part. This computation gives:
(It is not necessary to do a lengthy computation: the summands of the imaginary part are the products sin(a)cos(b) and cos(a)sin(b) as they involve exactly one i factor)
A calculator simplifies the imaginary part Im(x⁶) to 0
