Question

PLEASE HELP ME !! :(

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 source and the range of the signal

Answer 1

Do you know what sort of geometric figure is described by that equation?

Answer 2

@whpalmer4 im assuming its on a graph chart

Answer 3

okay, but is it a square, a triangle, a circle, pentagon, hyperbola, ???

Answer 4

its explaining the circumference of the radio signal in reference to a chart

Answer 5

circle

Answer 6

bingo! do you know the general form of the equation for a circle?

Answer 7

uhm no im not sure?

Answer 8

I don't think I know

Answer 9

okay, do you want to see how to figure it out?

Answer 10

A circle is just the set of points equidistant from the center point, right?

Answer 11

yes pleaseeee

Answer 12

right??

Answer 13

let's take the simplest case. That's a circle with the center at the origin (0,0), and radius of 1.

Answer 14

Now, the distance from the center to any of the points where the circle crosses the x or y axis is 1, right?

Answer 15

0,0 to 0,1 = 1
0,0 to 1,0 = 1
0,0 to 0,-1 = 1
0,0 to -1,0 = 1

Answer 16

ok yes
