Explanation:
I think you can try logging out from your account. Try cancelling your subscription. Before you do that, reach out to Brainly support.
It's either microsoft or office. Based on research I would say office.
I really hope this helps you! :-)
Answer:
Explanation: search engine uses system algorithm to search out items or information as required by the user. Example is google, chrome.
Data base are archives where information could be retrieve. Its contain information such as publications, abstract,journals.
Search engine provides wide range of information depending on you request while database are mostly for academics related materials.
Data base- A good place to generate this information is library, archivals while journal, publiications are kept while search engine can be used anywhere you have an internet facilities.
In a data base, information is searched in an organized way. The collections are already well arranged in different cubicle search engine provides wide range of information not organized.
Data base may contain more complex information not easily understood, search engine provides more elaborate answers.
Similarity of the two is that they both provide information.
They are both reliable.
School library is an example of where journals and publication are kept and can be retrived.
Answer:
-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂
Explanation:
2's complement is a way for us to represent negative numbers in binary.
To get 2's complement:
1. Invert all the bits
2. Add 1 to the inverted bits
Summary: 2's complement = -N = ~N + 1
1. Inverting the number
3874₁₀ = 1111 0010 0010₂
~3874₁₀ = 0000 1101 1101₂
2. Add 1 to your inverted bits
~3874₁₀ + 1 = 0000 1101 1101₂ + 1
= 0000 1101 1110₂
You can pad the most signigicant bits with 1's if you're planning on using more bits.
so,
12 bits 16 bits
0000 1101 1110₂ = 1111 0000 1101 1110₂
They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.
32 bits
= 1111 1111 1111 1111 1111 1111 1101 1110
