Given:

Equation of a circle

(x+4)^2+y^2=7

Required:

Find the center and radius of the circle. Then graph of circle.

Explanation:

We have a standard equation of circle

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

Whose radius is (h, k) and radius r.

We have equation of a circle

(x+4)^2+y^2=7

Now, we will compare with standard equation of a circle

We\text{ will get center\lparen-4, 0\rparen and radius }\sqrt{7}.

Graph of circle is

Answer:

Hence, this is the answer.

AlekseyPX
For the answer to the question above,  we will use this formula to solve this problem
<span>d = kv^2 </span>

<span>plugging in, </span>
<span>4.2 = k*10^2 </span>
<span>k = 0.042 </span>

<span>d = 0.042v^2 </span>

<span>the revoised equation will be </span>
<span>d = 0.9*0.042v^2 , i.e. </span>

<span>d = 0.0378v^2
