The definition of a circle uses the undefined term _______.

Mathematics

Answer:

C. Plane

Step-by-step explanation:

One definition of a circle is: "It is the set of all points in a plane that are at a given distance from a fixed point."

The undefined term is the word "plane."

You could define a plane as a flat surface with zero thickness and extends infinitely in all directions, but it isn't in the definition of a circle.

Euclid defined a plane as "a surface that lies evenly with the lines on it" before he defined a circle, so the meaning was understood.

A, B, and D are wrong. They aren't mentioned in the definition.

50 POINTS PLZ ANSWER CORRECTLY

belka [17]

Hey there! :D

So, we want to multiply that by 2. The table represents one year at Weatherford College.

8,965*2= 17,930

I heard the question mention 'reasonable'. It also said 'meet the cost'. So I would assume that 17,930 meets most of the cost. I think that's what it wanted to have. A couple thousand dollars may be reasonable, but will it meet the cost? Probably not.

I would say "A" is the best answer.

I hope this helps!

Complete this conjecture about multiplying powers of ten 10a over 10b= 10

jeyben [28]

For this case we have the following expression:

$\frac{10 ^ a}{10 ^ b}$

For power properties we have:

In the division, when we have the same base, the exponents are subtracted.

We then have to rewrite the expression:

$\frac{10 ^ a}{10 ^ b} = 10 ^ {a-b}$

Answer:

Completing the expression we have:

$\frac{10 ^ a}{10 ^ b} = 10 ^ {a-b}$
