How you use the Pythagorean theorem in 3D.

Answers

Answer:

If the base of the prism has dimensions x and y, and the diagonal along the base is represented by c, then x² + y² = c². The longest diagonal in the solid, s, is the hypotenuse of the triangle formed by the sides c and the height of the solid, z. So we know that, c² + z² = s².

solve the system of linear equations by substitution

Answers

Answer:

(-4, 5)

Step-by-step explanation (work shown in attached picture):

1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.

2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.

Since x = -4 and y = 5, the solution is (-4, 5).

Answer:

Value of x is -4 Value of y is 5

find the value of x.

Answers

x = 31

180 = 3x + 25 + 2x
180 = 5x + 25
-25. -25
155 = 5x
x = 31

Answer:

x=31

Step-by-step explanation:

Hello there!

the shown angles are supplementary meaning that the sum of the two is 180

so we create an equation

180=3x+25+2x

step 1 combine like terms

3x+2x

now we have

180=25+5x

step 2 subtract 25 from each side

180-25=155

now we have

155=5x

step 3 divide each side by 5

155/5=31

5x/5=x

we're left with x=31

Giorgio is learning to play the piano. By the end of each month, he has learned 3 new songs.

Part A Graph 5 points on the coordinate plane below that show the total number of songs Giorgio has learned by the end of each month from month 1 to month 5.

Which equation represents the relationship between the independent variable, x , and the dependent variable, y?

Answers

Answer: y = 3x

Step-by-step explanation:

The answer is y=3x because every month Giorgio learns a new song. so for the first month they learned 3 songs and in the second month they learn 3 more that adds up to 6 song total, so if you just times the month by 3 you will get your answer.

EMERGENCY HELP PLS: The state decided that the angle a wheelchair ramp
makes with the ground should be no more than 4.3º.
a) What is the maximum height of a 25-foot ramp? Round to the nearest tenth of a foot.
b) What distance along the ground would this ramp
cover? Round to the nearest tenth of a foot.
Maximum height = ? ft.
Distance along the ground ? ft.

Answers

Answer:

1.9 feets (nearest tenth) ;

24.9 feets

Step-by-step explanation:

Given that :

Angle, θ = 4.3°

Length of ramp = 25

Maximum Height, h ;

sinθ = opposite / hypotenus

Sin 4.3 = h / 25

0.0749787 * 25 = h

1.874 feet = h

1.9 feets (nearest tenth)

Distance along the ground the ramp could cover :

Cos θ = Adjacent / hypotenus

Cos 4.3 = x / 25

0.9971851 = x / 25

0.9971851 * 25 = x

x = 24.929

x = 24.9 (nearest tenth)

Given the function F (x) = x2 -2x -5 determine the average rate of change of the function over the interval -5 < x <6.

Answers

Answer:

Step-by-step explanation:

Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.

The average value of a function f(x) over an interval [a, b] is

f(b) - f(a)

ave. val. = ---------------

b - a

which in this particular case is

19 - 30

ave. val. = ----------------- = -11/11 = 1

6 - (-5)

The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.

The measures of the three angles of a triangle are given by x+4,x, and 2x. What is the value of x

Answers

Answer:

x = 44°

Step-by-step explanation:

The sum of all the interior angles of a triangle = 180°

so:

(x+4) + x + 2x = 180°

reducing:

4x + 4° = 180°

4x = 176°

x = 44°

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?
