Answer:
The correct answer to the following answer will be Cinematographe.
Explanation:
A motion picture camera apparatus which serves as a projector for a film is known as Cinematographe, invented by Louis Lumiere and Lyon by Auguste in the 1890s.
- We can use it both as camera and projector.
- It could be used to make extra prints of a film.
The other three options will not be the correct answer because:
Kaleidoscope (basically a toy having two or more reflecting mirrors inside it),
Kinetoscope (helps to view moving pictures without any sound) and
Vitaphone (helps to show images on the wall with the help of light rays).
Hence, Cinematographe is the right answer.
Answer:
Explanation:
Let n be an integer
Given that 
is odd
To prove that n is even
a) Proof by contraposition
Let be non odd
Then this would be a multiple of 2 being even
i.e. we get cube of n is odd since gives remainder 1 when divided by 2
It follows that n is odd.
Thus proved by contraposition
b) contradiction method:
If possible let is odd for n odd.
Then we get
since n is odd,
is odd being the product of three odd numbers
When we add 5, we get
is even being the sum of two odd numbers
A contradiction
Hence our assumption was wrong
if n is an integer and n^3 + 5 is odd, then n is even
