Answer:

Color contrast refers to the disparity in brightness between text (or any foreground item) and the background it is set against.

Explanation:

In the realm of web accessibility, the extent to which one color contrasts with another dictates whether the information can be easily read by most individuals.

Contrast creates visual differences and helps elements stand out.

Answer:

1. The home tab

2. Font group

3. The small arrow at the bottom right of the font command group.

4. Under "Font" heading (then "All text" subheading)

Explanation:

This explanation will guide Su in completing her task.

1. Navigate to the home tab;

2. From the home tab, Su will access a variety of command groups, but for her needs, she requires the Font command group.

3. A tiny arrow can be found at the bottom left of the font command group section; clicking it will unveil the font dialogue.

4. Within the font dialogue, there are two headings. The "font" heading and the "character spacing" heading.

For her purposes, she must focus on the "Font" heading, which includes various subheadings. To reach the underline color option, she needs to select the "All text" subheading.

Answer:

tryagain = "Y"

while tryagain.upper() == "Y":

    x1 = int(input("x1: "))

    y1 = int(input("y1: "))

    x2 = int(input("x2: "))

    y2 = int(input("y2: "))

    x3 = int(input("x3: "))

    y3 = int(input("y3: "))

    area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))

    if area > 0:

         print("Inputs form a triangle")

    else:

         print("Inputs do not form a triangle")

    tryagain = input("Press Y/y to try again: ")

Explanation:

To check for this, we will simply compute the area of the triangle given that inputs are on a coordinate plane i.e. (x,y).

An area greater than 0 means it's a triangle

Conversely, if not, it's not a triangle.

This line starts the loop with variable tryagain set to Y

tryagain = "Y"

while tryagain.upper() == "Y":

Following lines retrieve the triangle's coordinates     x1 = int(input("x1: "))

    y1 = int(input("y1: "))

    x2 = int(input("x2: "))

    y2 = int(input("y2: "))

    x3 = int(input("x3: "))

    y3 = int(input("y3: "))

Now, this computes the area

    area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))

Finally, this checks the condition mentioned above.

    if area > 0:

         print("Inputs form a triangle") This message appears if the condition is true

    else:

         print("Inputs do not form a triangle") This is printed if the condition is not met

    tryagain = input("Press Y/y to try again: ") It prompts the user to input new values

If a packet gets figuratively “sucked into a black hole” and is not received by the original sender, with no message returned to clarify the situation, there is an issue. This lack of communication indicates there is a problem with the _____.

A.) ICMP

B.) TCP/IP

C.) HTTP

D.) ISO

A.) ICMP
