Answer:

The modified program in Python is as follows:

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

wall_width = int(input('Enter wall width (feet):\n'))

area = wall_height*wall_width

print('Wall area:',area,'square feet')

paint_needed = area/350.0

print('Paint needed: {:.2f} gallons'.format(paint_needed))

print('Cans needed:',round(paint_needed),'can(s)')

color = input("Choose a color to paint the wall: ")

print("Cost of purchasing", color, "paint: $",paint_colors[color])

Explanation:

The italicized are given from the question [unchanged]

<em>import math</em>

<em> paint_colors = {'red': 35,'blue': 25,'green': 23} </em>

<em>wall_height = int(input('Enter wall height (feet):\n')) </em>

This gets input for width

wall_width = int(input('Enter wall width (feet):\n'))

Calculate the wall area

area = wall_height*wall_width

Print the calculated wall area

print('Wall area:',area,'square feet')

Calculate the amount of paint needed

paint_needed = area/350.0

Print the amount of paint needed to 2 decimal places

print('Paint needed: {:.2f} gallons'.format(paint_needed))

Print the amount of can needed to nearest integer

print('Cans needed:',round(paint_needed),'can(s)')

Prompt user for color of paint [here, we assume the user input is correct]

color = input("Choose a color to paint the wall: ")

Prints the corresponding amount for the color

print("Cost of purchasing", color, "paint: $",paint_colors[color])

gladu [14]

Answer:

Explanation:

try

clc

clear

close all

x=linspace(0,2*pi,7);

z=cos(pi.*x./3)

% the output on mine is to 4 decimals so it looks a bit different than what the output on your example is , but, I think if you change the format to decimal 2 it will look the same  :)

What is not true of efs
Lemur [1.5K]

Answer:

EFS cannot store files encrypted.

Explanation:

EFS) is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption. EFS is useful for mobile computer users, whose computer are subject to physical theft, and for storing highly sensitive data. Encryption itself is the method where the information is converted into secret code that hides the information's true meaning. (EFS) is used to encrypt files and folders. EFS is easy to use, with nothing more than a check box in a file’s properties. It is not fully supported on Windows 7 Starter, Windows 7 Home Basic, and Windows 7 Home Premium!

An object reference provides a(an)______for an object and is used to gain access to the object (Points : 2) entry
sdas [7]

Answer: Instance

Explanation: Instance is the term found in the object-orient programming concept. It is used for the realization of the variation present in any object specifically.The program execution at each time instant is known as the instance of program. Generation of realized instance is known as instantiation.

This helps in the accessing of the object in the program.Other options are incorrect entry , target and handle are not the technical term related with the accessing of object .Thus the correct answer is instance.

Review universal data models and discuss how these are being used more widely today. Does a data modeling project using a packag
adell [148]

Answer:

2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.

Explanation:

1a. Review of universal models:

A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.

A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.

1b. Discuss how these are being used more widely today.

*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.

*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.

*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.

2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.

I am having trouble figuring out if this is correct. Can someone please help me ASAP?
CaHeK987 [17]

Explanation:

The X's have been correctly placed in the chart

A surge suppressor, which is also commonly known as a surge protector, is an important equipment that helps prevent damage to electric components from an unexpected increase of voltage. Let’s assume that you are living in a county where the effective utility voltage is between 110 to 120 volts. Assume that the accepted peak voltage should not be anything higher than 170 volts. If there is a surge and this surge reaches peak levels of 170 volts and higher, surge suppressors should jump in and prevent the peak AC voltage from going above the threshold.

People tend to confuse line conditioners and surge suppressors. While surge suppressors protect components from surges, line conditioners are built to make up for the loss of voltage from the lines. It does so by storing some power energy. This stored energy can later be modified and used when the volts drops to the desired 110 volts.

A UPS has DC battery power that provides battery backup power when the electricity goes off or when the levels of voltage drop significantly. When the electricity goes off means that the voltage is at 0 volts and it is the work of the UPS to kick its backup power in.
