Match term definition diameter a) a segment between two points on a circle that passes through its center circumference b) a piece of the circumference of a circle radius c) circle a and a line segment connecting points b and c which are on the circle. secant d) the distance around a circle concentric circles e) circle a and a line segment connecting points b and c which are on the circle. arc f) two circles that share the same center.

Your options C and E are same.

The correct matches to the terms are :

Diameter - a segment between two points on a circle that passes through its center.

Circumference - the distance around a circle.

Radius - Circle A and a line segment connecting points B and C which are on the circle. It can also be defined as half of the diameter. or also a line segment connecting two points B and C like B is the center of circle and C is on the circle.

Secant - Circle A and a line segment connecting the points B and C which are both on the circle.

Concentric Circle - Two circles that share the same center.

Arc -  a piece of the circumference of a circle

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
