Answer:
Sir William Crookes invented the cathode ray tube in 1878, but these discoveries took many years to merge into the common ground of television. His mechanical system used a scanning disk with small holes to pick up image fragments and imprint them on a light-sensitive selenium tube. A receiver reassembled the picture.

<u>Answer:</u>
<em>A prototype for a function called isPrime that returns is true.</em>
<u>Explanation:</u>
Function prototype is just a skeletal part of the function which has <em>a return type, function name and the respective parameters. </em>
There is a difference between function and function prototype.
Function is nothing but a <em>function definition</em>, where it actually has all the lines of codes which need to be processed when it is called. It can be invoked any number of times and anywhere within the<em> scope of the function</em>. <em> </em>

<em>bool isPrime (int);

The question above wants to assess your interpretation of conic shapes and sections in art and architecture. For that reason, I can't write an answer for you, but I'll show you how to write it.
The conical sections can be seen in structures that assume one of the shapes considered conical. These formats are easy to identify, especially in architecture, where they are very popular. These shapes can be classified as Parabola, Circle, Ellipse, and Hyperbole
In this case, to write your answer, you should search for architectural works or works of art that present one of these types of conic sections and show how the use of this format is important for these works.
Some examples of works that use conic sections are:
- Parabola: Eiffel Tower.
- Circle: Farmer's Cottage Deluxe Summer House
- Ellipse: Tycho Brahe Planetarium.
- Hyperbole: McDonnell Planetarium
