The screen size of a TV is given by the length of the rectangular diagonal.
Traditional TVs come in 4:3 ratio, that is, the ratio of length to width is 4 to 3. This means, if the length is x inches, then the width is (3/4)x.
LCD TVs come in 16:9 ratio.
Instructions
Write a program that:
Prompts the user to input the length of the diagonal (in inches) of the screen
Allows the user to select which type of TV the user would like to view the dimensions for
Ex.1: Traditional TV area. 2: LCD TV Area 3: Both types of TVs area
Have the program calculate and display the:
Screen length
Screen width
Screen area
for the specified type of TV.
A county collects property taxes on the assessment value of property, which is 60 percent of the property’s actual value. If an acre of land is valued at $10,000, its assessment value is $6,000. The property tax is then 75¢ for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $45. Write a program that asks for the actual value of a piece of property and displays the assessment value and property tax.
Procedure 2. Write a program that takes the x-y coordinates of a point in the Cartesian plane
and prints a message telling either an axis on which the point lies or the quadrant in which it is
found. If x or y is 0, the code will print out "The point is on x or y axis".
For example, if your input x is 2.5, and y is 1, it will print out "The point is in Quadrant One"; if
the input x is -2.3, and y is -3.2, it will print out "The point is in Quadrant Three"; if the input x
is 0, and y is 20, it will print out "The point is on x or y axis ".
Requirements:
1. The inputs of x and y should be float data type.
2. The input should prompt a message on the screen to ask for the input x and y.
