What considerations have to be kept in mind with JPEG

1 answer:

8 0

JPEG is a file format for an image that will be compressed. Since it compressed the file size will be much smaller. That makes JPEG is one of the most used file types for images and was a default format for many application. But the drawback of compressing an image is that a portion of the data will lose and will cause the image quality dropped or produce a noise.

Does a triangle with sides of lengths 1.5 ft, 2.5 ft, and 2 ft form a right triangle? How do you know?

timama [110]

Answer:

Yes, the side lengths of 1.5, 2.5, and 2 ft form a right triangle.

Explanation:

Before we solve this problem, we need to know a couple of things.

In a right triangle, you have two legs and a diagonal line that goes from one leg to the other or from one side to the other. This line is called the hypotenuse. It is the longest side of a right triangle. This length can be calculated by using a special formula that is over a thousand years old.

The formula is called the Pythagorean Theorem.

The formula states that if you square one leg and the other leg and add it up. You get the side of hypotenuse which is squared as well.

Here it is in simple terms: $a^{2} +b^{2} =c^{2}$ .

a and b are your two legs.

C is your hypotenuse.

In this case 1.5 and 2 are your legs and 2.5 is your hypotenuse since it is the longest side.

Before we calculate, there is a converse to the Pythagorean Theorem.

If $a^{2} +b^{2} \neq c^{2}$ , then it is not a right triangle.

Lets make 1.5 for a

and 2 for b.

We know 2.5 is for c.

Here it is.

$1.5^{2} +2^{2} =2.5^{2}$ . The / means it is a fraction.

1.5 squared is 9/4 and 2 squared is 4. Add 4 and 9/4 and you get 25/4 squared. Take the square root of 25/4 and you get 5/2.

5/2 is equal to 2.5, so the Pythagorean Theorem applies to this triangle. Therefore, these side lengths do form a right triangle.

Hope this helps!

When one method calls another, which of the following statements are true?

jonny [76]

Answer:

I. The class methods and instance methods of one class may call the public class methods of another class using dot notation and referencing the name of the other class.

Explanation:

Private methods are being accessed from only within the class or scope specified. No other means of accessibility is possible, and even through inheritance. And instance methods can never call without using dot notation, any of the class method of the same class. Hence second and third options are not correct. And the class method and the instance methods of one class may call the public class methods of another class using the dot notation and referencing the name of the other class. Hence, the correct option is the first one.

(Disclaimer: I am not a professional, so it might not be the most concise answer possible, but I did run the Python script and it works)

Answer:

user_input = input("What food do you have in your refrigerator? ").lower()

count = 0

while True:

if user_input != 'apples':

count += 1

print(f'You have a {user_input} with a total of {count} food(s)\n')

user_input = input("What food do you have in your refrigerator? ")

else:

A security analyst accesses corporate web pages and inputs random data in the forms. The response received includes the type of

leonid [27]

Answer:

Option c is the correct answer for the above question.

Explanation:

The vulnerability is a term that is used to state that any system has some limitation by which the system causes an error while performing the action.
The above question states a software and asked the action which is used by the analyst to prevent the limitation. So the system will use the input validation.
It is because this prevents the error. it is because this will help to proceed with the wrong or invalid information on the database and the database or system can not hold the wrong data.
Hence option c is the correct answer while the other option is not correct because other options can not able to fix the limitation of the above system.
