Answer:
- Circle X with radius 2 cm.
- Either of two lines parallel to AB.
Step-by-step explanation:
1. The definition of a circle is all the points in a plane that are at some radius r from a given point (the circle center). That is what you have, with a radius of 2 cm.
__
2. Parallel lines are the same distance apart everywhere. Each line will have two parallel lines at some given distance from it, one on each side. Here, the separation distance from AB is 1 cm, so your locus of points is the two lines parallel AB that are 1 cm from it on either side.

Number of medium cherry slices : 10
number of medium orange slices : 40
ratio of cherry to orange : 10/40 reduces to 1/4 or 1:4 or 1 to 4
Answer:
16 degrees
Step-by-step explanation:
180 degrees = 164 degrees + x,
x = (180 - 164) degrees,
x = 16 degrees
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form 
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots
