<h3>
Answer: 5 - 4i (choice A)</h3>
===================================================
Work Shown:
x = the other number
(5+4i)*x = 41
x = 41/(5+4i)
x = 41*(5-4i)/( (5+4i)*(5-4i) ) ..... see note below
x = 41*(5-4i)/( 41 )
x = (41/41)*(5-4i)
x = 5 - 4i
As a way to check, (5+4i)*(5-4i) = 5^2+4^2 = 25+16 = 41
The rule used is (a-bi)(a+bi) = a^2 + b^2
-----------
Note: I multiplied top and bottom by (5-4i) to get rid of the imaginary term in the denominator.
The horizontal asymptote is the line which the curve approaches to cross but never crosses the boundary. The horizontal asymptote can be identified when the exponent in the denominator<span> of the function is larger than the exponent in the numerator. If not, no horizontal asymptote exists. WHen there is, we equate the denominator to zero and get x</span>
Were the question too answer sorry ?
Imagine that you have 8 apples which you want to hand out to 2 people. You want each person to get an equal amount of apples, so you decide to
give 2 apples at a time (one apple to each), until you run out or
you don't have enough to give each of the 2 people another apple. Notice
that each time you give out 2 apples, you have to subtract 2
from the total left over, and each person gets one apple. Let's
see what happens:
1. 8-2=6 -- each person now has 1 apple, and there are 6 more to hand out;
2. 8-2-2=4 -- each person now has 2 apples, and there are 4 more to pass out;
3. 8-2-2-2=2 -- each person now has 3 apples, and there are 2 more to distribute;
4. 8-2-2-2-2=0 -- each person now has 4 apples and there are no more apples to pass out.
Then you hand out 8 apples to 2 people and each of the get 4 apples. This meansthat 8÷2=4.
