3+5i/-2+3i perform operation

melisa1 [442]

Answer:

$\dfrac{9}{13}-\dfrac{19}{13}i$

Step-by-step explanation:

Remember $i^2=-1$

You are given the fraction $\dfrac{3+5i}{-2+3i}$

First, multiply the numerator and the denominator by -2-3i:

$\dfrac{3+5i}{-2+3i}=\dfrac{(3+5i)(-2-3i)}{(-2+3i)(-2-3i)}=\dfrac{(3+5i)(-2-3i)}{(-2)^2-(3i)^2}=\dfrac{(3+5i)(-2-3i)}{4-9i^2}=\dfrac{(3+5i)(-2-3i)}{4+9}$

This gives you 13 in denominator, now multiply two complex numbers in numerator:

$(3+5i)(-2-3i)=-6-9i-10i-15i^2=-6-19i+15=9-19i$

Thus, the initial fraction is

$\dfrac{9-19i}{13}=\dfrac{9}{13}-\dfrac{19}{13}i$

What is the slope of (1,2) (-3,-9)

kati45 [8]

Answer:

(11/4) is the slope

Step-by-step explanation:

1) Subtract the second y value (-9) by the first y value (2) in the coordinates. This equals 11.

2) Then, subtract the second x value (-3) by the first x value (1) in the coordinates. This equals 4.

3) Divide the answer you get for step one by the answer for step 2 and that's your slope. 11/4

45 students attend camp the number of 6th graders is one half the number of 7th graders. The number of 8th graders is the same a

slamgirl [31]

The number is fairly easy to come across. The first thing that I see is that there are 45 students at the camp. This means, based on the clues given to me, that the number of 6th graders is odd. Because the number of 6th graders is half the number of 7th graders, and 8th grade equals 7th grade, that you have to use an even number less than 20, but more than ten.This leaves the numbers 14 and 18. Now we use trial and error. Half of 14 is 7. 14+14=28
28+7=35
35≠45

Half of 18 is 9.
18+18=36
36+9=45
45=45

So the answer is as follows:
6th grade: 9
7th grade: 18
8th grade: 18
