I am writing to recommend Stacie Allen; Stacie is a very hard-working individual she's dedicated to her work and always wants to help others out. She accomplished many things while at Toms shoes.
Stacie dedicates all her time to her job and cares about everyone's wellbeing and happiness and is always there to pick people up. She has accomplished so many things and helps her company come up with ideas and better ways for us to do things.
I believe she would be great for this company,
<span>Pinhole cameras were one of the most sophisticated devices of the period, it made tasks much easier it basically worked exactly like the human eye and is something just like tracing.
Hope it helps! :)</span>
Answer: Reusing software device has some economical challenges such as:
- Investment cost in reusing the device is considered as the extra cost.It might require some extra components for the working to become usable
- Requires skilled person who can develop and design the software to be used again.The creating and designing of new software design is comparatively easy but making the system reusable requires someone who has more designing skill who will be highly paid for the work
- Cost of writing and reading of the software can also be considered as the economical challenge as the reused system created is to be studied by some other organization members or sources not familiar with the functioning. .
The logical expressions are
- (X NOR Y ) OR Z ⇒

- (A NAND B) AND NOT C ⇒

<h3>How to determine the
logical expressions?</h3>
<u>Logical expression 1</u>
X and Y are linked by the NOR gate.
So, we have:
X NOR Y
The X NOR Y is linked to Z by the OR gate.
So, we have:
(X NOR Y) OR Z
Hence, the logical expression is (X NOR Y ) OR Z ⇒ 
<u>Logical expression 2</u>
A and B are linked by the NAND gate.
So, we have:
A NAND B
The A NAND B is linked to C by the AND gate.
So, we have:
(A NAND B) AND C
Hence, the logical expression is (A NAND B) AND NOT C ⇒
