Answer:
Step-by-step explanation:
The standard equation for a circle is given by:
Where (h, k) is the center and r is the radius.
We know that the center is (-4, 8). So, substitute -4 for h and 8 for k:
Simplify:
Now, we will need to find r.
We know that it passes through the point (-2, -1). So, we can substitute -2 for x and -1 for y and solve for r. So:
Evaluate:
Square:
Add:
So, r squared is 85.
We don’t actually have to solve for r itself, since we will have to square it anyways.
So, we have:
Substituting 85 for r squared, we get:
And we have our equation.
Answer:
The Value of d is 5.
Step-by-step explanation:
Given:
We need to solve for d
Hence for solving for the term d we get;
Now we will use Addition property for equality and add both side by 8 we get;
Now we will use Division property for equality and Divide both side by 3 we get;
Hence the Value of d is 5.
