<u><em>Convert the equation of the circle in center radius form</em></u>
Group terms that contain the same variable
Complete the square twice. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
The center of the circle is (-3,8)
The radius of the circle is 8 units
<u><em>Verify each statement</em></u>
A. The center of the circle is (3,-8).
False
The center of the circle is (-3,8)
B. The circle is tangent to the x-axis
True
The circle is tangent to x=5 and x=-11 and is tangent to y=0 and y=16
Remember that y=0 is the x-axis
C. The circle has a radius of 64
False
The radius of the circle is 8 units
The diagonals of a parallelogram are congruent
The length WY is 32
<h3>How to determine the length WY</h3>Given that:
and
Then, we have:
diagonal
Subtract x^2 from both sides
Divide both sides by -6
The length WY is calculated as:
So, we have:
Substitute 8 for x
Simplify
Hence, the length WY is 32
