Answer:
Hi, for this exercise we have two laws to bear in mind:
Morgan's laws
NOT(А).NOT(В) = NOT(A) + NOT (B)
NOT(A) + NOT (B) = NOT(А).NOT(В)
And the table of the Nand
INPUT OUTPUT
A B A NAND B
0 0 1
0 1 1
1 0 1
1 1 0
Let's start!
a.
Input OUTPUT
A A A NAND A
1 1 0
0 0 1
b.
Input OUTPUT
A B (A NAND B ) NAND (A NAND B )
0 0 0
0 1 0
1 0 0
1 1 1
C.
Input OUTPUT
A B (A NAND A ) NAND (B NAND B )
0 0 0
0 1 1
1 0 1
1 1 1
Explanation:
In the first one, we only need one input in this case A and comparing with the truth table we have the not gate
In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.
In the third case we have that the OR is A + B and we know in base of the morgan's law that:
A + B = NOT(NOT(А).NOT(В))
So, we have to negate the two inputs and after make nand with the two inputs negated.
I hope it's help you.
On a graph, move 2 spaces to the right and from there move 18 spaces down. Now, where you've ended, make a dot. The distance fro the origin is -2/18 (as a fraction).
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
5 ( x + 4 ) = 4 ( x - 6)
5x + 20 = 4x - 24
5x -4x + 20= 4x - 4x - 24
1x + 20 = -24
1x + 20 - 20 = -24 - 20
1x = -44
check
5 (-44 + 4) = 4 ( -44 - 6)
5 (-40) = 4 (-50)
-200 = -200
Answer:
I grew up in the early internet stages. when i was young we would always have to sit at school, meetup somewhere, in town, or use the home phone. But when the internet was invented we could talk to each other through our computers at home. Old computers were so bulky and slow, but that was the coolest thing around. Now i can sit at home with my 20'' moniter on my 5g wifi and talking to my friends like theres no tomorrow. The internet has changed so much in the last years. If you were gonna tell me that one day ill be sitting at home playing games online and working from home on a laptop i would have told you that you were crazy.
