Answer:
she has saved $5 in the last 9 days because she has saved 500 cents the last 9 days there are 100 cents in a dollar which means she has to save $5
Answer:
1/2
Step-by-step explanation:
Sine is opposite over hyp.
So the opp is 5 and the hyp is 10
5/10 equal 1/2
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
-10.22, -7.89, -5.23, +34.98, +51.02, +51.22 because the closer a number is to 0 the smaller it is.
