If an occupation is projected to decline by 7% over the next 10 years, how would you rate the job outlook?

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance

Stels [109]

Answer:

#include <stdio.h>

int main()

{

float your_value1, your_value2, your_value3, your_value4, your_value5;

printf("Enter a frequency: ");

scanf_s("%f", &your_value1);//storing initial key frequency in your value 1

float r = 2.0 / 12;//typing 2.0 so it is treated as float and not int

your_value2 = your_value1 * r * 1; //initial*r*n

your_value3 = your_value1 * r * 2; //initial*r*n

your_value4 = your_value1 * r * 3; //initial*r*n

your_value5 = your_value1 * r * 4; //initial*r*n

printf("%0.2f %0.2f %0.2f %0.2f %0.2f", your_value1, your_value2, your_value3, your_value4, your_value5);

return 0;

}

Explanation:

The purpose of this exercise is to make you understand the difference between float and int. float variables are used when you need decimals in your calculations. int is used when you need integers. The problem in this exercise was the formulation of r. Now r is = 2/12, this means that when we type r as that, the computer assumes that it is an integer and treats it as such. So, it will convert the 0.166667 into 0. To overcome this, all you have to do is type 2.0 instead of 2 alone.

The %0.2 command restricts the float variable to 2 decimal places. By default, it has 6 decimal places.

I have used the function scanf_s instead of scanf simply because my compiler does not work with scanf.

I'm using assembly language. This is my assignment. I kinda confused about how to write code for this assignment. Can anyone exp

Brut [27]

Answer:

oid changeCase (char char_array[], int array_size ) {

__asm{

mov eax, char_array;

mov edi, 0;

readArray:

cmp edi, array_size;

jge exit;

mov ebx, edi;

shl ebx, 2;

mov cl, [eax + ebx];

check:

//working on it

cmp cl, 0x41;

jl next_indx;

cmp cl, 0x7A;

jg next_indx;

cmp cl, 'a';

jl convert_down;

jge convert_up;

convert_down:

or cl, 0x20; //make it lowercase

jmp write;

convert_up:

and cl, 0x20;

jmp write;

write:

mov byte ptr [eax + ebx], cl

next_indx:

inc edi;

exit:

cmp edi, array_size;

jl readArray;

mov char_array, eax;

}

Explanation:

Move char_array to eax as it is base image .
Use ebx as offset .
Use ecx as the storage register .
check if cl is <= than ASCII value 65 (A) .

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)

alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

$\dfrac{y-0}{x-4} = -4$

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

pentagon [3]

Answer:

XML (Extensible Markup Language):

Explanation:

XML (Xtensible Markup Language):

It is a markup language that is used for creating web-pages, it defines a set of rules that makes it readable both to humans and machine.

XML was primarily designed to be a software and hardware independent tool and it's focus was on data. XML provides a framework for defining markup languages.

XML, HTML and XHTML are all related to each other because they are all markup languages and can be used to build websites.

Basically,

-HTML is primarily for web-pages.

-XML is primarily for data.

-XHTML is a standard based on HTML that follows the strict rules of XML.
