Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~PAP Q~QvQ
NNADVOKAT [17]

Answer:

The statement \lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q is a tautology.

Step-by-step explanation:

We have the following statement \lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q

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 simple statements from the statement given are:

\lnot P, \lnot Q, \lnot P \land P, \lnot P \land P \rightarrow Q, and \lnot Q \lor Q with these you can construct the following truth table.

A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.

The last column contains only true values. Therefore, the statement is a tautology.

Helpp need this done ASAP
lorasvet [3.4K]
Number two is proportional just do Y over X y/x meaning divided all the y’s over the x’s so 25 divided by 5 30 divided by 6 35/7 40/8 they all equal 5 so it’s proportional
number three isn’t proportional when you do y/x they all come out differently so you do y2-y1 over x2-x1 16-4/4-2 16-4=12 4-2=2 then you divided 12/2 that equals 6 you do that again but with the next numbers but they don’t equal so it’s no equation no constant

Is this a function? Please help me! I literally cant do this!
julsineya [31]

Answer:

Yes, this is a function.

Step-by-step explanation:

This is a function because every input goes to exactly one output. Although 1 is listed twice in this example, it still goes to the same output of 15.
