<h3>How to identify the source and range of the signal?</h3>
Remember that a circle of radius R, centered at the point (a, b) is described by the equation:
In this case, we have the equation:
First, notice that 49 = 7², so we can rewrite:
Then, comparing this with the general circle equation, we can see that the center is at (5, -2) and the radius is R = 7.
Then the source is at (5, -2) and the range is 7 units.

Answer:
41.34
Step-by-step explanation:
We can use the Pythagorean theorem to solve for the distance. First we will create an <em>imaginary </em><em>triangle </em>with the leg lengths being the x distance and y distance between the 2 points and the hypotenuse being the distance between the 2 points.
x distance =
y distance =
We can now use the Pythagorean theorem (a²+b²=c²) with our <em>imaginary </em><em>triangle</em>
xdistance²+ydistance²=distance²
35²+22²=distance²
1709=distance²
In decimal form the distance would be around 41.34.
That is the answer
