Rachel is planning on writing code that will have to do computations with very large
numbers. Which of the following is the most important issue she should check
before writing her code?
PLEASE
Group of answer choices.
A. Rachel should look up how many bits are used to store integers and floating point numbers in the programming language she is using.
B. Rachel should reset her machine to store data using hexadecimal values instead of binary.
C. Rachel should run a program to ensure that she has enough memory on her machine to write the program itself.
D. Rachel does not have to worry about the size of the numbers
Answer:
A. Rachel should look up how many bits are used to store integers and floating point numbers in the programming language she is using.
Explanation:
In Computer programming, a bit is a short word for the term binary digit and is primarily the basic (smallest) unit measurement of data or information.
A bit is a logical state which represents a single binary value of either one (1) or zero (0). This ultimately implies that, a single bit in computer science represents a boolean value of;
1. True or ON, which is equal to one (1).
2. False or OFF, which is equal to zero (0).
Additionally, a binary numbering represents all numeric values that are to be written in sequences of ones (1s) and zeroes (0s). Therefore, a binary number refers to any numerical value (number) that is expressed in base-2 numerical system; 0s and 1s.
Also, the total numbers which can be represented with an 8 bit binary (base-2) system is 256.
For all computations that would involve the use of very large numbers, it's important to look up how many bits are used to store integers and floating point numbers.
In this context, Rachel should ensure that she check how many bits the chosen high-level programming language uses to store integers and floating point numbers before writing her codes.

Your knowledge of algorithms helps you obtain an exciting job with the Acme Computer Company, along with a $10,000 signing bonus. You decide to invest this money with the goal of maximizing your return at the end of 10 years. You decide to use the Amalgamated Investment Company to manage your investments. Amalgamated Investments requires you to observe the following rules. It offers n different investments, numbered 1 through n. In each year j , investment i provides a return rate of rij . In other words, if you invest d dollars in investment i in year j , then at the end of year j, you have drij dollars. The return rates are guaranteed, that is, you are given all the return rates for the next 10 years for each investment. You make investment decisions only once per year. At the end of each year, you can leave the money made in the previous year in the same investments, or you can shift money to other investments, by either shifting money between existing investments or moving money to a new investement. If you do not move your money between two consecutive years, you pay a fee of f1 dollars, whereas if you switch your money, you pay a fee of f2 dollars, where f2 > f1.
a) The problem, as stated, allows you to invest your money in multiple investments in each year. Prove that there exists an optimal investment strategy that, in each year, puts all the money into a single investment. (Recall that an optimal investment strategy maximizes the amount of money after 10 years and is not concerned with any other objectives, such as minimizing risk.)
b) Prove that the problem of planning your optimal investment strategy exhibits optimal substructure.
c) Design an algorithm that plans your optimal investment strategy. What is the running time of your algorithm?
d) Suppose that Amalgamated Investments imposed the additional restriction that, at any point, you can have no more than $15,000 in any one investment. Show that the problem of maximizing your income at the end of 10 years no longer exhibits optimal substructure.

You work for a retail clothing chain whose primary outlets are in shopping malls and are conducting an analysis of your customers and their preferences. You wish to find out if there are any particular activities that your customers engage in, or the types of purchases made in the month before or after purchasing select items from your store. To do this, you will want to use the data mining software you are using to do which of the following?
a. Identify clusters
b. Identify sequences
c. Classify data
d. Identify associations
Answer: Identifying sequences
Explanation:
Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.
In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.
Therefore, the best option is B.

write difference between dvd r and dvd ram( Any 3 points or any a little big paraph for test)
Answer:
Following are the differences two the given questions:
Explanation:
DVD-R:
DVD-R is a common DVD recordable media that seems like a conventional DVD, and it can only be used once for writing data or analyzing information many times.It is identical to a regular DVD, however, it can be used to record data like a CD-R. Once a DVD-R is "burned," it cannot be read to anymore.There is a 650 nm range recording, nicknamed "Authoring DVD-R." "DVD-R for general" is another format with protection against duplicating, which records at 635 nm. Whilst DVD-R(a) and DVD-R(g) may read forms of one another, they cannot write formats of each other.DVD-RAM:
This is a technology for optical DVD storage where the information may be read, deleted & written constantly.It offers outstanding integrity of data, preservation, and avoidance of damages that can be used for basic storing data, data preservation, or data backup.Those disc drives can indeed be frequently recorded and deleted, and only compatible with DVD-RAM format devices produced by corporations.list three social implications of the wider range of piracy

A college student borrowed his roommate's notebook computer without permission because he needed to write a term paper that was due the next day. While the computer was sitting open on the student's desk overnight, a water pipe in the ceiling began leaking and water dripped down on the computer, rendering it inoperable. A computer repair service estimated that it would cost $500 to repair all the damaged components. At the time it was damaged, the computer was worth $700. If the roommate sues the student for the damage caused to the computer, what will be the extent of his recovery
Answer: $700
Explanation:
Based on the information given in the question, if the roommate sues the student for the damage caused to the computer, the extent of his recovery will be $700.
In this scenario, the student has committed a conversion as the right of possession of the roommate's computer was interfered with by the student as he took it without the roommate's permission, which later sustained damage that was more than 70% of the computer's value. In such case, the extent of the recovery will be the fair market value which is $700.
