PLEASE HELP ASAP! Write the equation in standard form for the circle with radius √43 and center (4, − 7).

Step-by-step explanation:

The standard equation of a circle is given by:

Where (h, k) is the center and r is the radius.

We are given that the center is (4, -7) and that the radius is √(43).

So, h = 4, k = -7, and r = √(43). Substitute:

Simplify. Hence, our equation is:

step-by-step :

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
