The median of the stem-and-leaf plot is 23
Option A:
is the equation of the circle
Explanation:
The equation of the circle is 
We need to write the equation of the circle in standard form.
Let us subtract 10 from both sides of the equation.
Thus, we have,

Grouping the terms,we have,

Now, we shall complete the square, let us add and subtract the equation by 9 to write the term
in the form of 
Thus, we have,

Simplifying, we get,


Similarly, we shall complete the square for the term
in the form of 
Thus, we have,

Simplifying, we get,


Thus, the equation of the circle in standard form is 
Hence, Option A is the correct answer.
Answer:
D
Step-by-step explanation:
only b and d have the equation equal on both sides
and only D has it that 5 is the hypotenuse, and the opposite angle is 90 degrees
