Assume that a chocolate bar consists of n squares arranged in a rectangular pattern. The entire bar, a smaller rectangularpieceo

motikmotik

Step-by-step explanation:

Claim:

it takes n - 1 number of breaks to break the bar into n separate squares for all integers n.

Basic case -> n = 1

The bar is already completely broken into pieces.

Case -> n ≥ 2

Assuming that assertion is true for all rectangular bars with fewer than n squares. Break the bar into two pieces of size k and n - k where 1 ≤ k < n

The bar with k squares requires k − 1 breaks and the bar with n − k squares

requires n − k − 1 breaks.

So the original bar requires 1 + (k−1) + (n−k−1) breaks.

simplifying yields,

1 + k − 1 + n − k − 1

1 - 1 + n - 1

n - 1

Therefore, we proved as we claimed that it takes n - 1 breaks to break the bar into n separate squares.

If p and q are both true, then which of the following statements has the same truth-value as ~p → q?

olganol [36]

If p and q are both true, then

$\neg p \implies q$

is an implication of the form

$F \implies T$

which is true, because every implication starting with false is true, i.e.

$F \implies T = T,\quad F \implies F = T$

So, we're looking for an expression evaluating to true. Let's see what we have:

A) is an AND proposition. Logical AND is true only if both parts are true. So, you have

$\neg P \land \neg Q = F \land F = F$

So it's not the right option.

B) is an OR proposition. Logical OR is true whenever one of the two parts is true. So, you have

$\neg P \lor\neg Q = F \lor F = F$

So it's not the right option.

C) is again an AND proposition. You have

$P \land \neg Q = T \land F = F$

So this is not the right option.

D) Finally, the last one is again an implication, and again it starts with false:

$\neg Q \implies P = F \implies T = T$

So this is true, and thus is the correct option.
