What defines a circle? a) two rays with a common endpoint b) a piece of a line with two end points c) a piece of a line with one end point d) all coplanar points equidistant from a given point

The answer is choice D. All coplanar points equidistant from a given point.

In other words, all points that arethe same distance away from a fixed point. For example, if you have some fence post and you are 2 feet away from the fencepost, then that marks one point on the circle. Then move to another point that is also 2 feet away from the fencepost. Repeat until you have a bunch of points. All of these points will form a circle. The term "coplanar" means "all in the same plane". A plane is a flat surface like a flat piece of paper that doesn't bend or curve.

b

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
