Chapter 2, Problem 14PE
(Hard drive storage capacity) If you buy a 40 GB hard drive, then chances are that the actual storage on the hard drive is not 40 GB. This is due to the fact that, typically, a manufacturer uses 1,000 bytes as the value of 1K bytes, 1,000 K bytes as the value of 1 MB, 1,000 MB as the value of 1 GB. Therefore, a 40 GB hard drive contains 40,000,000,000 bytes. However, in computer memory, as given in Table 1-1 (Chapter 1), 1 KB is equal to 1,024 bytes, and so on. So the actual storage on a 40 GB hard drive is approximately 37.25 GB. (You might like to read the fine print next time you buy a hard drive.) Write a

pizza (python)Mario owns a pizzeria. Mario makes all of his pizzas from 10 different ingredients, using 3 ingredients on each pizza. Mario’s cousin Luigi owns a pizzeria as well. Luigi makes all his pizzas from 9 ingredients, using 4 ingredients on each pizza. Mario and Luigi have made a bet: Mario believes that customers can order a larger selection of pizzas in his pizzeria than they can order in Luigi’s pizzeria. Use functions for this assignment.
Implement a factorial() function yourself (do not use the one from the math module)
When choosing k items from n possible items, the number of possibilities can be obtained using the following formula:
(??)=?!?!(?−?)!(nk)=n!k!(n−k)!
Make a function called choose with two parameters n and k, that implements the above formula.
Write a program that calculates the number of pizzas Mario and Luigi can make. The outcome should look like this:
Mario can make 120 pizzas.Luigi can make 126 pizzas. Luigi has won the bet.
Assume we are using constructive solid geometry (CSG) in 2D with union
U, intersection n, and subtraction / operations. Check the example below
to see how to draw a circle and draw the results of other cases using CSG.
Example:
circle(3,2, 1); //a circle centered at (3,2) with radius 1
write a code that decodes the coloured bands on a resistor.Each colour band printed on a resistor has a corresponding numeric value, as shown in the table below:
Colour

2
orange
3
yellow
4
green
5
blue
6
violet
7

8
white

To calculate the total resistance value, the following formula should be used:
resistance=(10a+b)⋅10^c
where a, b, and c are the numeric values of the first, second, and third colour bands respectively.
For example, let's say that the colour bands on a resistor are red-green-orange. In this case, a=2, b=5, and c=3 (using the table). Hence the resistance value is 25000 ohms:
resistance=(10*2+5)⋅10^3=25000 ohms
Your task is to write a program which asks the user to input the three colour bands. The program should then calculate and output the resistance value indicated by the bands.
As part of your solution, you must define and use a function named colour_to_number. This function should take one…

- (Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft).

For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ftarrow_forwardCorrect and detailed answer please.

Because you only recently started programming, you are not very quick at writing code, and can only write 20 lines of code each hour. However, the more code you write, the faster you become, and so the number of lines you can write each hour changes. ⦁ If the number of lines you are writing increases by seven lines each hour, calculate the total amount of lines you would have written after 10 hours.⦁ If the amount of lines increases by a factor of 1.2 each hour, calculate the total amount of lines you would have written after 8 hours.⦁ You and your friend are both working on writing simple programs, whenever one of you finishes a program; they go outside to take a small break, then returns to work on the next program. If you need 112 minutes to write one program, and your friend needs 150 minutes to write one, after how many minutes will both of you be outside together for a break?arrow_forward
