which of the following statements about the evolving relationship between traditional newspaper operations and blogging is true?

Alex_Xolod [135]

Newspapers will continue to collapse or have their newsroom staffs substantially reduced as a result of their excessive debt.

One of these was advocacy journalism, where the journalist actively advances a specific cause or point of view. Early American newspapers were partisan and sensational, but in the late nineteenth and early twentieth century, they started to become more objective and professional. Many journalists have been confused by the fall in recent years since readers don't seem to be all that interested in reading newspapers. The decline in newspaper production is caused by a number of factors, including social media, corporate ownership, internet access, and advertising. Three of the four primary purposes of mass communication—surveillance, correlation, and cultural transmission—involve journalism to a significant extent.

Suppose Alice, Bob, and Carol want to use secret key technology to authenticate each other. If they all used the same secret key

HACTEHA [7]

Answer:

No. This is not more secure.

Explanation:

this is not more secure than having all of Carol, bob and Alice having the same key.

alice would be able to know Carol's key for her to be able to verify the answer Carol gave to a challenge by her. she would also have to know bob's key to do the same.

any of these 3 would have to know someone else's secret key to verify answers to any challenge.

the challenge is to know the secret keys if the other two and if done, decryption can easily be done and they can impersonate.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:

sdas [7]

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]

import math

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

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

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])

(Exhibit: Production Possibilities Curves 2) Assume that a nation is operating on production possibilities curve CD. Economic gr

Alex

Answer:

b. shift from curve CD to curve EF.

Required Details of the Question:

The image of the curve required to answer the question has been attached.

Explanation:

A production possibilities curve shows various combinations of the amounts of two goods( in this case capital and consumer goods) which can be produced within the given resources and a graphical representation showing all the possible options of output for the two products that can be produced using all factors of production.

Now the growth of an economy is best illustrated in the image by the shift from curve CD to curve EF, this means that as the nation's production capacity increases, its production possibilities curve shift outward showing an increase in production of both goods.
