Answer: $6.75
Step-by-step process:
100%-25%=75%
therefore, they will cost 75% of the original price
75% of $9.00 = .75*9
= $6.75

Answer:
- 0.5 + 2.985i
- 1 + 2.828i
- 1.5 + 2.598i
- 2 + 2.236i
Explanation:
Complex numbers have the general form a + bi, where a is the real part and b is the imaginary part.
Since, the numbers are neither purely imaginary nor purely real a ≠ 0 and b ≠ 0.
The absolute value of a complex number is its distance to the origin (0,0), so you use Pythagorean theorem to calculate the absolute value. Calling it |C|, that is:
Then, the work consists in finding pairs (a,b) for which:
You can do it by setting any arbitrary value less than 3 to a or b and solving for the other:

I will use b =0.5, b = 1, b = 1.5, b = 2

Then, four distinct complex numbers that have an absolute value of 3 are:
- 0.5 + 2.985i
- 1 + 2.828i
- 1.5 + 2.598i
- 2 + 2.236i
Answer:
The answer is D
Step-by-step explanation:
$13.95 divided by 100 = 1% which is equal to $0.1395
To get 15% of her bill, you need to multiply $0.1395 by 15 which gives you $2.0925. You then round this to 2 significant figures, which totals to $2.10.
