Step-by-step explanation:
2x²+3x-2=0
(2x-1)(x+2)
x+2=0
x=-2 (no, because x must be >0)
2x-1=0
2x=1
x=½ (yes, because x>0)
Answer: Radius: 1) from point H to point A and 2) from point H to point G
Diameter: 1) from point E to point A and 2) from point D to point G
Step-by-step explanation:
Radius is from the exact point of the middle of the circle until the circumference.
Diameter is a straight line passing from side to side through the center of the circle.
Answer:
Step-by-step explanation:
A circle is a curve sketched out by a point moving in a plane. If the distance from A to C is 6 units, then the distance from C to B is 6 units.
<h3>What is a circle?</h3>
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
If the distance from A to C is 6 units, then the distance from C to B is 6 units. This is because AC and BC are the radii of the circle, therefore, both are equal to each other.
