1 answer:
Delicious77 [7]2 years ago
4 0

Answer:

E) all of the above

Explanation:

Your device can track your location, which means that it will tell where you've been. When you post on social media or just online, you are sharing what you're thinking. Your friends and family can easily be traced back to you, so they know who your friends and family are, and we leave evidence of what we've done because whatever you click gets tracked. hope this helps :)

Suppose that a computer can run an algorithm on a problem of size 1,024 in time t. We do not know the complexity of the algorith
Setler79 [48]

Answer:

Time Complexity of Problem - O(n)

Explanation:

When n= 1024 time taken is t. on a particular computer.

When computer is 8 times faster in same time t , n can be equal to 8192. It means on increasing processing speed input grows linearly.

When computer is 8 times slow then with same time t , n will be 128 which is (1/8)th time 1024.

It means with increase in processing speed by x factor time taken will decrease by (1/x) factor. Or input size can be increased by x times. This signifies that time taken by program grows linearly with input size n. Therefore time complexity of problem will be O(n).

If we double the speed of original machine then we can solve problems of size 2n in time t.

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?
Ganezh [65]

Answer:

The correct answer to the following question will be "Adaptive Optics".

Explanation:

  • AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
  • It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.
  • It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.
  • Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.

Therefore, Adaptive Optics is the right answer.

We initialize the parameters to all zero values and run the linear perceptron algorithm through these points in a particular ord
Usimov [2.4K]

The main aim of running the parameters in the linear perceptron algorithm is to be able to develop a machine learning algorithm for binary classification tasks.

<h3>What is a linear perceptron algorithm?</h3>

This refers to the linear classification algorithm that is used in machine learning.

This is done in order to learn a decision boundary that divides different classes using a hyperplane.

Hence, we can see that your question is incomplete because the parameters are not included, hence a general overview was given to give you a better understanding of the concept.

Which of the following is used to allocate memory for the instance variables of an object of a class?1. the reserved word public
kodGreya [7K]

Answer:

The correct answer to the following question will be 2. the operator new.

Explanation:

New operator is used to allocating the memory to the instance object.The new object can be created by using a "new" keyword in java .

Syntax of using 'new' operator is :

class_name object_name=new class_name() // it allocated the memory to the class

For Example :

ABC obj = new ABC;  

Now, this time obj points to the object of the ABC class.

obj = new ABC ();

call the construction of ABC class
