Question 1: SinC remains at the same point because SinC is the vertex of the triangle, it determines the height of the triangle and the length of the sides.

Question 2: In an obtuse triangle, you would always want the sides add up to more than the hypotenuse for a triangle to be able to form. In an acute triangle, the height would always need to be the smallest, like BC>AC>h. The general rule to be able to make a triangle would be AC>BC>h.

Cyber Bullying

The article talks about how many people has stirred trouble through the internet, pretending to be someone else. It has gotten so serious that there is now a law on it. It is now illegal to even say you are someone else and say mean things to others. If you break that law, you would reciece a $1,000 fine. I think that it's right to make this law because I have witnessed so many tims of cyber bullying through the internet, and it can be really hurtful. It might maybe help at least reduce the amount of people who does cyber bullying.

Cyber Bullying

Cyber bullying is making posts and comments on the Web under someone else's name. It's now a serious issue and the government has made a law to prevent it from worsening. Impersonating someone is illegal and you can get charged for nearly $1,000 for doing so. I think bullying itself is something very hard to withstand and now we also have to deal with cyber bullying? I honestly think that people must not have anything better to do. I have definetly witnessed cyber bullying countless of times in the internet. I think that having this bill is good because it prevents most people from cyber bullying. I know if I was getting cyber bullied, I would want something tod be done about it.

Remedial college classes cost billions

Many students in their high school years aren't taking their studies seriously which leads to students having to spend more money just to cover things that they could've learned for free, in high school. Studies that many students are spending around 2 billion in school learning what they were suppose to have learned. The reason for this article is for students to know and understand that college is no joke and they should start taking it more seriously. This article makes people realize that suceeding in high school may not certainly mean you would do well in college. So you should always challenge yourself to new things so you can be more prepared.

Solving Problems with Trignometry

Chapter 1 Project: Modeling with Linear Regressions

I went to www.weather.yahoo.com to find the temperatures of the cities I had picked. With those temperatures, I made a table chart. Then, I had to find the linear regression equation, y = ax+b. which was y = .7543228031x + 29.44718828. I then picked three other cities, finding their highest and lowest temperatures. Since I was told to predict the high temperatures of the cities. I substituted the lowest temperature for x in my regression equation, and then solve for y, which would be the highest temperature. The temperatures I got from the regression model was nowhere near the actual high temperatures. But my correlation coeffcient is r^2 = .7849262744 , r = .8859606506

Chapter P Project.

For my project, I did P.4 example 8. For the example, you need to find the slope, y2-y1/x2-x1 of the points that were given. After you find the slope, you then plug the slope into the point-slope intercept form, y-y1=m(x-x1) to make a linear equation, Ax+By=C. Then simplify the equation to a point intercept form, y=mx+b where y is by itself. And also graphing the answers I got with the equation..

Chapter P: Graphing Functions

Back to school night Extra Credit: My mom never got a proper education so she was rather delighted to knoe that she was learning some math. She got confused alot since it was new to her and it was pretty complicated since I had to translate into another language. She eventually got the hang of it and got pretty much the main point of it. Even though she didn't finish, she at least learned something new.

First, I had to draw the original function(in black) which is y= l x l. Next, I drew the vertical translation(in red) where I moved up the y-axis 7 units up and the equation was then y= l x l +7. Afterwards, I drew the horizontal translation(in blue) where I moved 4 units to the left on the x-axis, and the equation would then be y= l (x+4)^2 l. Then, I drew the vertical and horizontal translation(in green) where I moved 7 units up the y-axis and 4 units to the left, x-axis and the equation would be y= l (x+4)^2 l +7. Then, I drew the vertical reflection of the original function across the x-axis and the equation would be y=-l x l. Lastly, I drew the reflection (across the x-axis) of the vertical and horizontal translation. I would first reflect across the x-axis, moving 4 units to the left on the x-axis, and going down 7 units on the y-axis, the equation would equal y= l -x+4)^2 l -7. In total, I did 5 transformations excluding the original function.
