A monthly loan payment of $200 is something you can manage. When will the debt be paid off? As a hint, a while time will be beneficial. Just the interest will be a perpetual payment, which is 100/0.005 = 20,000.
What does that loop in mean?In computer programming, a loop is a set of commands that are regularly carried out up until a particular condition is satisfied. Typically, a specific action is carried out, such as acquiring and altering a piece of information, and then a criteria is checked, such as evaluating whether the count had reached a specific value.
Calculation
We will calculate the present value of a 100 dollars monthly payment discounted at 6% annual rate compounded monthly.
the monthly rate will be the annual rate divided by 12 months within a year:
6% / 12 = 0.5% = 0.005
A perpetuity will be a payment wich only cover the interest :
100 / 0.005 = 20,000

An array is a data structure used to store a collection of items. Items in an array are typically stored in sequential memory locations, and each item can be accessed with an index number. Arrays can store any type of data, including numbers, strings, objects, and even other arrays. Arrays are commonly used in programming to represent collections of data, such as a list of student grades or a list of product prices. Arrays can also be used to store data structures, such as linked lists and binary trees. Arrays are often used to speed up operations such as searching and sorting, as the data is stored in a pre-determined order. Arrays can also be used to generate random numbers, and to simulate mathematical equations. Arrays are typically fixed-size, meaning that once a certain number of elements have been added, no more can be added. However, dynamic arrays can be resized to accommodate more elements.

In the four-component performance formula, the CPU time is determined by (select all):
• Instruction count
• Compilation time
• CPI
• Clock rate
CPU time = Instruction count * CPI / Clock rate.
What is the formula for calculating CPU time?
CPU efficiency is a measure of how well an application utilizes its requests for CPU. Efficiency is calculated with the following formula: efficiency=cpu_time / (run_time x number_of_cpus).The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). A “cycle” is technically a pulse synchronized by an internal oscillator, but for our purposes, they're a basic unit that helps understand a CPU's speed.The execution time or CPU time, which we call Ci, is the total amount of time that the process executes; that time is generally independent of the initiation time but often depends on the input data. We often define deadlines for periodic processes, but we may also want to define a deadline for an aperiodic process.To learn more about CPU refers to:

The predicate is WHERE FirstName = 'Tim'.
What is ORDER BY ?
ORDER BY is a clause used in SQL statements to sort data in either ascending or descending order. It can be used to sort data by one or more columns and allows for the specification of the direction (ascending or descending) of the sorting. SQL (Structured Query Language) is a standard language for storing, manipulating and retrieving the data in databases. It is used by many relational database management systems for example such as Oracle , Sybase, and Access. SQL is used to query, update, and manage databases.
