Answer:

Step-by-step explanation:
The equation for a circle is given by:

Where (h,k) is the center and r is the radius.
The center is the red dot, which is (1,2). Thus, h=1 and k=2.
To find the radius, you need to use the distance formula. We are given two coordinates: the center (red dot) at (1,2) and a blue dot on the circle at (2.5,4). Find the radius by using the distance formula:

Let (1,2) be <em>x₁ </em>and <em>y₁ </em>and let (2.5,4) be <em>x₂ </em>and <em>y₂. </em>Therefore:

Thus, r is 2.5.
Plugging these numbers into the equation, we have:

Answer:
Horizontal Asymptote: x = 0
Vertical Asymptote: x = 5
Step-by-step explanation:
The function is given as 
<em>Horizontal asymptotes are found by equating numerator to 0 and solving for x</em>
<em>Vertical asymptotes are found by equating denominator to 0 and solving for x</em>
<em />
<u>Horizontal Asymptote:</u>
x = 0
<u>Vertical Asymptote:</u>
x - 5 = 0
x = 5
