Answer:

Given,

P = (22, 1, 42, 10)

Q = (20, 0, 36, 8)

a. Formula for Euclidean Distance :

distance = ((p1-q1)^2 + (p2-q2)^2 + ... + (pn-qn)^2)^(1/2)

Now,

distance = ( (22-20)^2 + (1-0)^2 + (42 - 36)^2 + (10-8)^2) ) ^(1/2)

=( (2)^2 + (1)^2 + (6)^2 + (2)^2 ) ) ^(1/2)

=(4+1+36+4)^(1/2)

=45^(1/2)

Distance = 6.7082

b.Manhattan distance :

d = |x1 - x2| + |y1 - y2|

d = |22- 20| + |1 - 0|

d = |2| + |1|

The operating systems, and utility programs that perform system

Phantasy [73]

Answer:

System softwares.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

Basically, softwares are categorized into two (2) main categories and these are;

I. Utility software.

II. System software.

The operating systems, and utility programs that perform system maintenance and protection tasks such as error correction and backup are called system softwares.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

On the other hand, a utility software can be defined as a software application or program designed to add more functionality to a computer system, as well as to improve its performance efficiently. Some examples of commonly used utility tools in computer are file and folder backup tools, file management, antivirus, hard disk diagnostics, registry cleaner, network performance monitor, screensavers etc.

Neko [114]

Answer:

D. Create a cell reference in a formula by typing in the cell name or clicking the cell.

Further Explanation:

To create a cell reference in a formula the following procedure is used:

First, click on the cell where you want to add formula.

After that, in the formula bar assign the equal (=) sign.

Now, you have two options to reference one or more cells. Select a cell or range of cells that you want to reference. You can color code the cell references and borders to make it easier to work with it. Here, you can expand the cell selection or corner of the border.

Again, now define the name by typing in the cell and press F3 key to select the paste name box.

Finally, create a reference in any formula by pressing Ctrl+Shift+Enter.

Write a program to draw a text-based graph of a mathematical function f(x)

Makovka662 [10]

I have a very good example of the program you need written on Python. You can use this (sorry for bad tabulation):
import math import math def main(): function = input("Enter a function f(x):\n") x = 0 y = 0 for rows in range(10,-11,-1): for col in range(-10,11,1): x=col roundfx = round(eval(function)) if roundfx == rows: print("o", end="") if rows==0 and col==0 and not rows == roundfx: print("+", end="") if col == 0 and not rows == 0 and not rows == roundfx: print("|", end="") if rows==0 and not col==0 and not rows == roundfx: print("-", end="") else: if not rows == 0: if not col == 0: if not rows == roundfx: print(" ", end="") print() main()
