1.Given the rotation of triangle ABC shown below, determine the counter-clockwise angle of rotation that occurred about point D. Show all relevant lines and measurements you made to determine your answer.
A) 180°
B) 90°
C) 130°
D) 50°

Answers

Answer:

D. 50º

Step-by-step explanation:

According to the image below attached, blue lines represents line segments [tex]DB[/tex] and [tex]DB'[/tex], the red line creates a right angle regarding [tex]DB[/tex] (90º), where green line creates a flat angle with the same respect (180º). The angle between [tex]DB[/tex] and [tex]DB'[/tex] is less than 90º and 180º, meaning an acute angle. Therefore, the right answer is D.

So, I am solving your concept based on an assumed graph which I have attached. It would anyways clear your concept.

Answer:

Please check the explanation!

Step-by-step explanation:

Given the attached graph below, it is clear that the right angle triangle ABC is shown.

Here are some of the information we can get from the right angle triangle ABC such as:

The angle at C = 30°side AB = 8 units

We have to determine the unknown side 'x' using the trigonometric ratios

As

tan Ф = opp/adjacent

From the diagram it is clear that

Ф = 30°

opp=8

adjacent = BC = x

so

tan Ф = opp/adjacent

tan 30 = 8/x

1/√3 = 8/x

x = 8×√3

x = 13.9

Therefore, the missing length will be: x = 13.9

Answers

Answer:

For the first part

1.) Negative

2.)zero

3.) undefined

4.) positive

The point slope formula is y-y1=m(x-x1). It is best to use if you already know the slope and one other point on the line. It is used to find another point on the line.

The slope-intercept form is used to show a line. To use this form, you need to know the slope and the y-intercept.

The slope formula is y=mx+b. M is the slope while b is the y-intercept.

The equations of the line that passes throught the point given in the table are as follows;

[tex]y = -\frac{1}{6} x+\frac{1}{3}[/tex]

[tex]y-2=-\frac{1}{6}(x+10)[/tex]

Equation of a straight line

The linear equation of a striaght line is represented as follows:

y = mx + b

where

m = slopeb = y-intercept

Therefore,

m = 1 - 2 / -4 + 10

m = - 1 / 6

Let's find b using (-10, 2)

2 = - 1 / 6(-10) + b

2 = 5 / 3 + b

b = 2 - 5 / 3

b =  6 - 5 / 3

b = 1 / 3

hence,

[tex]y = -\frac{1}{6} x+\frac{1}{3}[/tex]

using y - y₁ = m(x - x₁)

y₁ = 2

x₁ = -10

m = - 1 / 6

Hence,

Write the slope- intercept form of the equation of the line described through (4,5) parallel to y= 1/4x-4

Answers

Answer:

y = 1/4 x + 4

Step-by-step explanation:

1. Because the new equation is parallel to y= 1/4x - 4 => the slope is still the same => New equation : y = 1/4x + b ( b is a number that we'll find now)

2. Put x = 4 and y = 5 in the new equation

=> 5 = (1/4)(4) + b

=> b = 4

3. So then we'll have the new equation that is parallel to y = 1/4x-4

91%

Step-by-step explanation:

we can use combinations:

Total probabilities = 12! / (4!8!) = 479,001,600 / 967,680 = 495

Probability of no defective unit = ₁₀C₄ = 10!/4!6! = 3,628,800 / 17,280 = 210

Probability of one defective unit = ₁₀C₃ · ₂C₁ = 10!/3!7! · 2!/1! = 120 · 2 = 240

Probability of no more than one defective unit = (210 + 240) / 495 = 450 / 495 = 91%

The sum of 4 thirteens and 16 thirteens, need answer ASAP :(

Answers

Answer:

260?

Step-by-step explanation:

I used the equation (4)13+(16)13 and plugged it into my calculator and got 260.

The sum of 4 thirteens and 16 thirteens is 260.

What is the meaning of sum?

You add up all the numbers to arrive at the sum. When you summarise something, you pay attention to all of its crucial components. A specific sum of money can also be referred to using the word sum. You might have to spend a sizable sum of money on a new car. However, you might be able to justify spending so much if you add up or total all of its advantages. When you add up the costs of everything you ordered, the total on a restaurant bill is determined. Sum need not be restricted to numbers. When you summarise something, you're providing a summary or overarching statement about it.

Here, 4 thirteens = 4 × 13 = 52

16 thirteens = 16 × 13 = 208

Sum of 4 thirteens and 16 thirteens = 52 + 208 = 260

Hence, 260 is the correct answer.

Okay so we know that b is 6 and that h is 10 so we can change the question to this : 1/2 + 6 + 10. We know that 1/2 is also writen as 0.5 , now all you need to do is 0.5 + 6 + 10 = 16.5 . The question asks to round to the nearest 10th so you need to add a 0 after the 5 so you can round up or down.

16.50

Now you need to look at the 10th number which is 5 and to round it up you need to look at the number after that which would be 0, we know that anything that is 4 or below gets rounded down so your answer for this question is simply 16.5.

Each paragraph should be 5-7 sentences in length. Sticks and stones may break my bones, but words can never hurt me. This age-old adage has been passed down through the generations. Typically, its an offhand response from a parent to a child when someone has said something that hurt the childs feelings. After all, as long as theres no physical damage, then everything must be fine, right? Hurtful words are often treated as inconsequential. People assume they can be easily brushed aside and smoothed over with a flimsy apology on the part of the perpetrator. But the truth is, words can hurt in more ways than one and the effects often far outweigh any scrape or bruise. In todays world, our stories are no longer limited to simple word-of-mouth tales or even hard-bound books. Words are digital and far-reaching, passed around on websites, on social media, and in text messages. More often than not, the words we publish online are not really for the benefit of others, but for ourselves. Writer Gracy Olmstead says, in the world of internet and social media, another narrative has begun to reign supreme: namely, the self-narration. So, what happens when the words we use become more about self-gratification than genuinely helping or communicating with others? The result can be anything from shameless selfies to cyberbullying, and the effects are tangible. The Texas Education Code defines bullying as an act that exploits an imbalance of power and involves written or verbal expression. This has recently expanded to include digital forms of communication. These include sending vicious text messages, emails or instant messages, and spreading rumors or gossip by posting it to social networking sites. The sneaky thing about cyberbullying is that because its not physical, we underestimate its negative effects. With the anonymity and distance the internet provides, cyberbullies dont have to face the consequences of their actions, and often feel free to say whatever they want about others. History has proven that words can be just as potent weapons as if not more so than sticks and stones. During World War II, the Nazi regime employed propaganda to impress upon German civilians and soldiers that the Jews were not only subhuman but also dangerous enemies. The words of the German government became the defining narrative of an entire group of people. While this false propaganda seems a far cry from the problems facing teenagers today, they all demonstrate the impact of words. Novelist Chimamanda Ngozi Adichie put it simply when she said that the stories we tell are often about power. Power is the ability not just to tell the story of another person, but to make it the definitive story of that person, Adichie said. Perhaps the answer is not to fight to be heard, but rather to learn to listen. When we are empowered to tell our own stories or share our own points of view, our words can have positive, transformative effects. They can help people understand other experiences and see the world differently. Now that youve read about the effects words can have, what do you think? Has anyone ever said something about you that was hurtful or untrue? What did you do about it? How have you used words to solve a problem, bring people together, or share your own story? Why do words matter? Please help!
