-(2) maths

Answers

Answer:

Let get small number is x and large number is y.

The difference between two numbers is 308328.

ie. y- x = 308328.

If the smaller number is

6524.

So, x= 6524.

Hence,

y - x = 308328

y- 6524 = 308328

y = 308328 + 6524

y = 314852

Answers

Answer:

y = 2x - 22

Step-by-step explanation:

y = 2x + 1

Parallel slope: 2

(7, -8)

y - y1 = m(x - x1)

y + 8 = 2(x - 7)

y + 8 = 2x - 14

y = 2x - 22

Answer:

Solution given:

equation of line 1 is:

y=2x+1

2x-y+1=0.......[1]

slope of line 1 is

m1=[tex] \frac{ -coefficient \:of\: x }{coefficient\: of \:y} [/tex]

[tex] \frac{ - 2}{ - 1} = 2[/tex]

Since the lines are parallel than slope of another line m2=m1=2

It passes through (x1,y1)=(7,-8)

equation of a line is:

(y-y1)=m2(x-x1)(y+8)=2(x-7)y+8=2x-142x-y=8+142x-y=22[tex] \frac{2x}{22} - \frac{y}{22} = 1[/tex][tex] \frac{x}{11} - \frac{y}{22} = 1[/tex]

is a required equation of a line in slope intercept form.

Answer:

y = - [tex]\frac{3}{2}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-3}{2-0}[/tex] = - [tex]\frac{3}{2}[/tex]

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = - [tex]\frac{3}{2}[/tex] x + 3 ← equation of line

In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.

Answers

Answer:

11699 square centimeters

Step-by-step explanation:

In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.

When given two sides of a triangle and an angle, the area of the triangle is calculated as:

1/2jksintheta

theta = 173°

Hence:

Area of triangle =

1/2 × 800 × 240 × sin 173

= 11699.456967 square centimeters

Approximately = 11699 square centimeters

ANSWER ASAP! PLEASE I BEG YOU!Passage A: Andrew Carnegie: A Friend of the People1 What makes a successful life? A look at the life of Andrew Carnegie offers some clues. Carnegie was a nineteenth-century industrialist who rose from poverty to build a steel empire. He ultimately became the richest man in the world. His success was largely a product of his study of business and industrial trends and of his management of his relationships with well-connected people.2 Carnegie was poor when he arrived in the U.S. at the age of 13, but his habits of study and personal skills enabled him to rise quickly. He worked long days and weeks in a textile mill, but read widely and applied himself to the study of bookkeeping at night. At 14, he landed a job as a messenger in a telegraph office. He again studied to get ahead, memorizing a street map of Pittsburgh, the locations of local businesses, and the faces of important businessmen. He also became one of only three people in the U.S. at the time to learn to decipher Morse code by ear. His work paid off when he was promoted to the position of telegraph operator, and his skills soon made him the fastest operator in his office. At 17, Carnegie caught the attention of a railroad superintendent, Thomas A. Scott, who hired him as his personal secretary. In this quick succession of events, it is easy to see how Carnegie used his immense drive and skill to lay a foundation for his later success.3 As a developing and eventually successful businessman, Carnegie advanced through a continued close attention to relationships and to his eras business and industrial trends. He worked closely at Scotts side. There he learned about stocks and making sound investments. At the close of the Civil War, he left the railroad. Hed decided that he could better realize his goal of attaining a fortune by building upon his interests in iron. When he later expanded into the steel industry, Carnegie assessed the current technology and decided to apply what is known as the Bessemer process to his production method. This enabled him to increase production while keeping his prices low. Ultimately, this allowed him to rule the industry. As he built his companies, he carefully maintained and grew his relationships with Scott and the railroads president, J. Edgar Thomson. He named his first steel mill after Thomson, and he offered both men opportunities to invest in his ongoing ventures.4 Beyond his business achievements, he was a man who gave much to others. He donated hundreds of millions of dollars to education, the arts, free public libraries, and foundations dedicated to world peace. His generosity has improved the lives of generations of people. He died a rich man, in more ways than one.Based on the first text, what did Carnegie's relationship with Thomas A. Scott contribute to his eventual success? A. business sense and connections B. an entry into the steel business C. telegraphing and secretarial skills D. a fortune to invest in stocks Calculate the pH of a solution with [H+] =1x10^-5 define investment bank. what is 7p = -42 i need help i cant find the answer Could someone please help me find the missing X?
