Which is the most precise definition of a circle?

2 answers:

8 0

The best answer is D.

A is incorrect because that means that all squigly lines that have ends that meet are circles, which is false.
B is incorrect because this is not very precise as a definition. Also, compasses are not completely perfect, so the points are slightly off from being completely equidistant from the point.
C is incorrect because that's describing a sphere (notice how it says space instead of plane).

D. The set of all points in a plane that are equidistant from a fixed point.

Y is directly proportional to x,and y=216 when x=2. Find y when x=7.

makkiz [27]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=216\\
x=2
\end{cases}\implies 216=k2\implies \cfrac{216}{2}=k
\\\\\\
108=k\qquad therefore\qquad \boxed{y=108x}
\\\\\\
\textit{when x = 7, what is \underline{y}?}\qquad y=108(7)$

Determine whether the following statement is a tautology, contradiction, or neither (~PVQ) ~Q Tautology Contradiction • Neither

Tom [10]

Answer:

The statement $(\lnot P \lor Q)\rightarrow \lnot Q$ is neither a tautology nor a contradiction.

Step-by-step explanation:

A tautology is a statement that is always true.

A contradiction is a statement that is always false.

We are going to use a truth table to determine whether the statement $(\lnot P \lor Q)\rightarrow \lnot Q$ is a tautology, contradiction, or neither

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The statement $(\lnot P \lor Q)\rightarrow \lnot Q$ is compound by these simple statements:

$\lnot P$
$\lnot Q$
$(\lnot P \lor Q)$

and we are going to use these simple statements to build the truth table.

The last column contains true and false values. Therefore, the statement is neither a tautology nor a contradiction.

soo are these real math questions? I mean like do your teachers actually ask you these kind of questions or you are making all this up? because they seem to have no answers for them at all

I hope this is a joke tbh
