Question

( What is the Radius for 32? )... Graph the circle (x + 2)2 + (y + 1)2 = 32. Label the center and at least four points on the circle.

Answer 1

Hint:
Rewrite 32 as:
\[(\sqrt{32})^{2}\]

Answer 2

The square of a square root = whatever is under the square root

Answer 3

I know. I already did that and got, 5.65 but how would I graph that.. A little over five?

Answer 4

Yeah..just estimate.

Answer 5

6 ? lol

Answer 6

I would go with 5.5 ish for the radius approximation.

The center is at (-2,-1).

So, start at -2 and move 5.5 units to the left and then to the right in a horizontal motion.

Then, start at -1 and move 5.5 units up and then down in a vertical motion.

What would those 4 sets of coordinates be?

Answer 7

okay, one moment while I get my coordinates.

Answer 8

Wow, I think I have my coordinates backwards. Ugh!

Answer 9

How?

Answer 10

I named the points incorrectly. What did you get?

Answer 11

okay, so I have the cords. (-2,6.5) , (3, 1.5) , (-2, -4.5) and ( -7 , 1.5 )

Answer 12

Second Attempt

Answer 13

Did we get the same answers?

Answer 14

Check these two.

Answer 15

@dopegyal_

Answer 16

Check graph of coordinates of center on screenshot.

Answer 17

(3.5, -1) , (7.5 , -1)

Answer 18

It look so uneven...

Answer 19

Check this one: (7.5 , -1)

Answer 20

Plus, the center on your screenshot is incorrectly located.

Answer 21

Does that matter? The numbers are still there.

Answer 22

oh I got it. -7, 1.5

Answer 23

I don't know what is being submitted. If you are submitted the graph for grading, then it is wrong. If it is just the numbers that you are submitting, then the graph does not matter, I suppose.

Answer 24

I'm submitting everything. ):

Answer 25

omg.

Answer 26

(-7.5, -1)

If you are submitting the graph, then you need to fix the center.

Answer 27

This is the graph I was provided with though, I just screen shot it and pasted it on my paint.

Answer 28

The grid and maybe the circle, yes. But, who wrote the incorrect coordinates of the center of the circle on the graph?

Answer 29

Question: Is this typed in correctly? --> (x + 2)^2 + (y + 1)^2 = SQRT(32)

Answer 30

Yes, the original question is in the screen shot.

Answer 31

Maybe it's just to trick us, and have us thinking outside the box. Lol...

Answer 32

If you want to submit a graph with the center marked in the wrong place, then it's on you. :)

Answer 33

):

Answer 34

Are you supposed to locate the points on the graph? This problem is giving me a headache. ):

Answer 35

Do you have the screenshot on this problem?

Answer 36

Yes, I am supposed to. Here, let me send the screenshot of my work.

Answer 37

That looks correct to me.

Answer 38

What about this: are you supposed to label the four points and give the coordinates on the graph. You put them up top in a list but look at the instructions.

Answer 39

Is this that awesome screenshot program from the other night? I need to put it on my machine if it is.

Answer 40

No. I just did what you told me to do before, with the print screen button.

Answer 41

Okay. Look, what about e-mailing the teacher and finding out if the c(0,0)rdinates of the four points are supposed to be shown on the actual graph or if it is okay just to list them.

Answer 42

Then, we can move on.

Answer 43

Directrix you're overthinking this. You need me to screenshot the directions as well?

Answer 44

He wants the coordinates on the graph, this is why he provided us with it. Not for advertisement.

Answer 45

I already read them. Ask your teacher if I'm overthinking. :) And, is there such a thing as overthinking, I wonder.

Answer 46

Let's move on before I think too much more. :)

Answer 47

Lol. If he says he wants us to graph it.......... I've waisted so much time. ))): I have 10 problems!

Answer 48

Post the next one.

Answer 49

okay(:
