Question

17. the equation (x+6)^2+(y+4)^2=36 models the position and range of the source of a radio signal. describe the position of the sorce and the range of the signals. (3 points)
I don't get this at all help please :(

Answer 1

\[(x+6)^{2}+(y+4)^{2}\] I'm not sure I understand. seems like \[(x+y+10)^{2}\]
I know it doesn't help much. I am still kinda young.

Answer 2

As In should be in pre algebra, or learning algebra, stuff like that.

Answer 3

i just need the describe the position of the sorce and the range of the signals. part really ii need to explain it :/ im completely lost

Answer 4

If its like a graphing thing, your best bet is probably graph 6 or 36 on the x, 4 or 16 on the y. If not, your best bet is coolmath.com . I learn almost EVERYTHING there

Answer 5

ok ill try that too

Answer 6

That has to be one of THE best math assistance sites.

Answer 7

ok so that site is really confusing and hurts the eyes o.o too many colors

Answer 8

LOL. I know, right? You just get used to it after a while.

Answer 10

this is the equation of a circle

the general form is

\[(x - h)^2 + (y - k)^2 = r^2\]

the centre of the circle is (h, k)

the radius is r

match your equation to the general form to find the centre and radius

Answer 11

i know that much but what i don't get is how i would do the describing part

Answer 12

describe the position of the sorce and the range of the signals <-- how would i do that

Answer 13

well start with the origin and use compass directions

6 units west and 4 south of the origin and the signal strength is 6 units (the range)

Answer 14

ok i think i get it now thank you

Answer 15

you could even draw a number plane and show the centre and draw a circle of 6 units..

Answer 16

so the radio mast, centre of the signal is... as above...
