Match the term radius arc chord secant tangent circumference (c-e have corresponding pictures that will be in order down below) a.) a line that intersects a circle in exactly one point b.) the distance around a circle c.) circle a and a line segment connecting points b and c which are on the circle. d.) circle a and the portion of the circle between points b and c is darkened. e.) circle a and a line segment connecting points b and c which are on the circle. f.) f) a segment between the center of a circle and a point on the circle

Radius matches with option F.

Arc matches with option D.

Chord matches with option C.

Secant matches with option E

Tangent matches with option A

Circumference matches option B

Step-by-step explanation:

Given the diagram in which chord is given, arc is given and secant is given.

we have to match the terms with their characteristics.

Radius is a segment between the centre of a circle and a point on the circle where the distance is same from each point of circumference to center.

Radius matches with option F.

Arc is the portion of the circle between points B and C is darkened represented in figure 2.

Arc matches with option D.

Chord of a circle is a line segment connecting points B and C which are on the circle shown in circle 1.

Chord matches with option C.

Secant is a line segment connecting points B and C which are on the circle shown in circle 3.

Secant matches with option E

Tangent  that is a line intersects a circle in exactly one point.

Tangent matches with option A

Circumference is the distance around a circle.

Circumference matches with option B

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
