what do you call the horizontal number line in the Cartesian plane ?​

Answers

9514 1404 393

Answer:

  x-axis

Step-by-step explanation:

The horizontal and vertical axes of a graph can have any names you like. If the independent variable represents something in particular, the horizontal axis is usually named so as to indicate that. In a graph of distance versus time, for example, the independent variable is likely to be time, and the horizontal axis is likely to be named something that suggests that--"t," for example, or perhaps "days".

It is fairly conventional to use "x" to name a general independent variable. The corresponding dependent variable in a two-variable relation is conventionally called "y". The horizontal axis in x-y graphs is usually labeled "x" and is called the "x-axis."

This convention is sufficiently well-used that we often call the horizontal number line of the graph the "x-axis" even if it is labeled something else.

A scientist needs 180 milliliters of a 20% acid solution for an experiment. The lab has available a 25% and a 10% solution. How many milliliters of the 25% solution and how many milliliters of the 10% solution should the scientist mix to make the 20% solution

Answers

9514 1404 393

Answer:

120 mL of 25% solution60 mL of 10% solution

Step-by-step explanation:

Let q represent the quantity of 25% solution in the mix. Then 180-q is the quantity of 10% solution. The quantity of acid in the mix is ...

  0.10(180 -q) +0.25(q) = 0.20(180)

  18 +0.15q = 36 . . . . simplify

  0.15q = 18 . . . . . . . . subtract 18

  q = 18/0.15 = 120 . . . . divide by the coefficient of q

  180-q = 60

The scientist should mix 120 mL of 25% solution with 60 mL of 10% solution.

What is the slope-intercept form of an equation of a line that passes through the point (0,-1) and is perpendicular to 5x-y=3?

Answers

Answer:

y = -1/5x - 1

Step-by-step explanation:

Perpendicular lines slopes are negative reciprocals of each other.

Write the given equation in the slope-intercept form: y = mx + b

5x - y = 3

-y = -5x + 3

y = 5x - 3       multiply by -1

The slope of the given line is 5 ( the coefficient of the x-term).

The slope of the new equation will -1/5 (this is the negative reciprocal of 5).

Next find "b"  using y = mx + b, the new slope -1/5 and the point (0, -1)

y = mx + b

-1 = -1/5(0) + b

-1 = 0 + b

-1 = b  

Now write the equation y = -1/5x - 1

Up arrow, right arrow, down arrow, left arrow, up arrow, right arrow, down arrow, left arrow. What's the conjecture

Answers

Answer:

The correct option is;

If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) Right-arrow (x, -y).

If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) Right-Arrow (-x, y).

Taking the result from the first reflection (x, -y) and applying the second mapping rule will result in (-x, -y), not (y, x), which reflection across the line y = x should give

Step-by-step explanation:

We have that for reflection across the x-axis, (x, y) → (x, -y)

For reflection across the y-axis, (x, y) → (-x, y)

Therefore, given that the pre-image before the reflection across the y-axis is (x, -y), we have;

For reflection across the y-axis, (x, -y) → (-x, -y)

For reflection across the line, y = x, gives (x, y) → (y, x) which is not the same as (-x, -y)

A softball bat and glove are on sale for $89.95. If the sale price is discounted 10% from the original price, what was the original price? Round to the nearest cent.

Answers

Answer:

$20.40

Step-by-step explanation:

20% off means that the new price of the skirt will be 80% of the original price:

$30(100%  – 20%) = $30(80%)

Converting the percent to a decimal gives:

$30(0.8) = $24.00

There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:

$24(100%  – 15%) = $24(85%)

Again converting the percent to a decimal gives:

$24(0.85) = $20.40

Given: D is the midpoint of AC, ED = FD, and angle EDA = angle FDC

Prove that: Triangle AED = Triangle CFD

Answers

Answer:

Step-by-step explanation:

Side-Angle-Side postulate (SAS)

There are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.

What are congruent triangles?

Two triangles are said to be congruent if their corresponding sides and angles are equal.

As per the given question,

D is the midpoint of AC, ED = FD, and angle EDA = angle FDC

In ΔAED and ΔCFD,

Side DE = Side DF

m∠EDA  = m∠FDC

Side AE= Side FC

According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.

Thus, both triangles are congruent.

Hence, there are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.

Im Also a Scientist1Olive was sitting on her best friend Jessicas porch with about a dozen other kids from school. It was the beginning of the school year, and they had all decided to catch up over pizza and talk about their summers. They were all shrieking with laughter from a story that Lizzie had just told about her summer job. 2So far, Lizzies summer had been the most eventful. She had been a counselor at a soccer camp where they were so serious about soccer that they made the kids do everything with their feet. Lizzie was once caught using her hands to hold her toothbrush and had to sing Im a Little Teapot in front of the entire camp! Olive laughed so hard at Lizzies story that grape soda came out her nose, sending everyone into another fit of hysterical laughter. 3After the kids had caught their breath, Alex reached for another slice of pizza. What about you, Olive? he asked, smiling at her. What did you do this summer? As everyone turned to Olive to hear her story, Olives giggle slowly faded. This was the moment shed been worried about all summer. How would she explain her summer job to her friends without sounding like a complete geek? 4There were two things that Olive loved most of all: science and mysteries. Her favorite books, TV shows, and movies, were always about murder mysteries, heists, and solving crimes. Over the past year, Olives science teacher, Ms. Welborn, noticed that Olive showed a strong aptitude for science and moved her to the most advanced chemistry class, where Olive held her own among much older students. Finally, just before summer break, Ms. Welborn had asked Olive if shed be interested in working over the summer in a professional laboratory. Theres one thing I should clarify, just so you understand, Ms. Welborn had told her. This isnt just any kind of labits a crime lab. And so, well, sometimes, you might be examining and analyzing some grisly stuff. Itll mean a lot of hard work and critical thinking. You very well might be involved in a few cases. Olives eyes had nearly bugged out of her head. Mrs. Welborn continued, saying, Would you be interested? Id understand if you said no. Olive said yes so loud and so suddenly, Ms. Welborn jumped. Well, she grinned, thats excellent, then. Ill call my friend and set it up.5The entire summer had been incredible. Olive couldnt wait to get up in the morning to help the crime lab find missing children and convict criminals. In school she had learned about chemical composition, molecular structures, and isotopeseverything that had just been concepts and chapter headings in her textbooks suddenly became real, living science. The schedule was gruelingOlive was up at five o clock every morning and often collapsed into bed near midnightbut she knew that this was definitely what she wanted to do for a living.6The problem was, would her friends understand? All summer Olive avoided hanging out with her friends or being social in any way. She was terrified that they would think she was a complete weirdo for wanting to spend her summer cooped up in a windowless laboratory, wearing a lab coat and goggles. She had considered being really vague, avoiding the questions, or even just outright lying and saying she worked somewhere elseor didnt even have a summer job at all. But now, after everything she had learned this summer, Olive wasnt afraid to be honest about who she was. Hanging out with her friends, sitting on her best friends porch on a warm September night, Olive felt invincible. 7I worked at a crime lab, she said casually. It was really cool.8There was a stunned silence as everyone reacted to what Olive had said. You mean, like, you did science stuff all summer long? Alex asked. Olive nodded, her nerve faltering a little. Colby, a tall boy with frizzy hair, sort of giggled. Wait, a crime labso, there was blood and stuff? Olive nodded again. She was really beginning to wish she had just lied and said that she worked at a fast food place in the mall. But then, she glanced over at Alex, who was looking at her with raised eyebrows. Thats pretty awesome, Alex said. Colby nodded, too. Cool, he added.9Olive felt her shoulders droop in relief, and a smile spread across her face. Yeah, she agreed. It was cool.

Millions of people who lost their life savings and their jobs eventually became homeless, only to find that their president, Herbert Hoover, felt the government should not intervene. However, New York governor Franklin Delano Roosevelt said, "I pledge myself to a New Deal for the American people." And when he was elected to office in 1932, he made good on that pledge. Through a series of programs, he stimulated the economy, got people back to work, and protected the American people through the Great Depression. In 1935, for example, Roosevelt created the Works Progress Administration (WPA). The WPA created much-needed jobs for the unemployed, at the same time improving the country as a whole. WPS workers erected buildings like schools and post offices. They also worked on bridges, highways, and other infrastructure projects. In addition, the WPA found work for people with artistic capabilities, such as writers, musicians, and theater directors. In fact, WPA murals still exist. You may have seen them in places like zoos, courthouses, and hospitals. The WPA, which existed until 1943, provided work and a paycheck to almost 9 million Americans. Later that year, Roosevelt signed the Social Security Act of 1935. At a time when people had lost muchif not allof the money for which they had worked, the Social Security Act guaranteed pensions to millions of Americans. It also established unemployment insurance so people who had lost their jobs could receive money until they found work. Thanks to Roosevelt's initiative, these policies are still with us today and continue to protect many Americans when they need help the most. In many ways, Roosevelt saved the United States. He believed the government should become the active force in driving the country toward prosperity and held to that idea regardless of any opposition. In 1941, the Japanese bombing of Pearl Harbor ignited World War II, and the war effort helped to accelerate the production of goods and services in the United States. Ultimately, this ended the Great Depression and put the country back on the road to prosperity. However, it was Roosevelt's programs that held the United States together for so many years by providing work, income, and hope in a time of unprecedented economic terror. cronografia se describe como Interviewing TechniquesLexie, a marketing manager, regularly interviews candidates for her team.
