Answer:
(-4,1)
Step-by-step explanation:
The given parabola is
When we rewrite in vertex form, we get;
Or
When we compare to:
We have 4p=-4
This means p=-1
But the vertex is at:
(-4,2)
Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.
Hence the focus is (-4,1)
Answer:
A. KM
Step-by-step explanation:
A circle is named by its center. Circle K has its center at point K.
A radius is a line segment that extends from the center of the circle to a point on the circle. Point K must be one end of any radius.
<h3>Application</h3>Segment KM is a radius.
Segments between points on the circle are <em>chords</em>. The other named segments in the answer choices are all chords of the circle.
