<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.
Answer:
to get a percent you would get the decimal and move it two places and you will get 115.21%
Step-by-step explanation:
with 1.1521 you will get the decimal and move it to the right to get 115.21%
I would use the formula
Initial x multiplier^time
So the initial is 7,500, the multiplier will be 1.03975 and then it would be to the power of 10 (time).
7500 x 1.03975^10 = $11,075.17
