Answer:

$(p\vee q)\wedge(\neg p\vee r)\equiv(p\wedge r)\vee(\neg p\wedge q)$

Explanation:

The statements are logically equivalent if they have the same truth tables. So let´s use truth tables in order to determine if they are logically equivalent or not:

The picture that I attached you shows the truth table for each case. As you can see in the highlight columns:

$(p\vee q)\wedge(\neg p\vee r)\equiv(p\wedge r)\vee(\neg p\wedge q)$

They are logically equivalent because they have exactly the same truth values between each other. Hence, we can conclude that they are logically equivalent.

Answer: B

Explanation:

WHATS GOOD DAVE STRIDER? WHATS UP MAN I - i man put the bunny back in the box what pumpkin apple juice?

ok so application software performs specific tasks for an end user and utility software just runs routine maintenance on your computer to ensure it runs smoothly. in this sense, the answer is B because if your computer crashed then you have no backup. things do not run smoothly obviously.

think of utility software as things such as antivirus, compression tools, defragmenter, and the other boring stuff that is meant for your computer to run smoothly
