3 0

Answer:

1/2 or 0.5

Step-by-step explanation:

First think: How many numbers are there between 5 and ten that are odd?

5,7 and 9 are all odd (that makes 3 numbers)

Then you take that and divide it by the total number of numbers between 5 and 10

5,6,7,8,9,10 (that makes 6 numbers)

You then get 3/6, simplified to 1/2 or 0.5

What is the quotient of the complex number 4-3i divided by its conjugate?

almond37 [142]

Answer: C. $\frac{7}{25}-\frac{24}{25}i$

Step-by-step explanation:

1. You have the following division:

$\frac{4-3i}{4+3i}$ (As you can see, to find the conjugate of 4-3i you must change the sign between the terms).

2. To solve this division, you must multiply the numerator and the denominator by the conjugate of the denominator, as following:

$=\frac{(4-3i)}{(4+3i)}\frac{(4-3i)}{(4-3i)}=\frac{16-12i-12i+9i^{2}}{16-9i^{2}}$

3. Keeping on mind that $i^{2}=-1$ , you have:

$=\frac{16-12i-12i+9(-1)}{16-9(-1)}$

4. Simplifying:

$=\frac{7-24i}{25}=\frac{7}{25}-\frac{24}{25}i$

5. The result is:

$\frac{7}{25}-\frac{24}{25}i$
