Answer: (B) It's easier, cheaper, and more reliable to build machines and devices that only have to distinguish between binary states.
Explanation:
The representation of the digital data in the computer system in the binary form because it is easier and cheaper to use in the system. It is more reliable to build the machine and the devices for distinguish the binary states.
Computer basically uses the 0 and 1 binary digits for storing the data in the system. The computer processor circuits are basically made up of the various types of transistors that uses electronic signals for the activation process in the system.
The o and 1 are the binary digits that reflect the different states of the transistor that is OFF and ON state.
Answer:
Let f be a function
a) f(n) = n²
b) f(n) = n/2
c) f(n) = 0
Explanation:
a) f(n) = n²
This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.
Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:
f(a) = f(b) ⇒ a² = b² ⇒ a = b
The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.
b) f(n) = n/2
The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:
f(2n) = [2n/2] = n
The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:
When the value of n=1, then
n/2 = [1/2] = [0.5] = 1
When the value of n=2 then
n/2 = [2/2] = [1] = 1
c) f(n) = 0
The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
word = whatever value you want.
if "mold" in word:
print("Mold is in the variable word.")
else:
print("Mold is not in the variable word.")
Python has a help page on google I would definitely recommend that. Here is a link to the beginners guide https://wiki.python.org/moin/BeginnersGuide
High-level language programs must be translated into machine language before they can be executed. (Machine language instructions are encoded as binary numbers that are meant to be used by a machine, not read or written by people. The Java compiler translates Java programs into a language called Java bytecode.
