# Math reflexion

Today we are doing a reflection on our math this semester.

1. I thought that the blog posts were super dumb when I was actually doing them, but when it came to studying your for finals, it was really helpful to listen to my self explain something I didnt remember

2. It’s really helpful to do the practice tests in the work books because it is harder than the home work, but it works on your understanding and gives you a challenge

3. I did not enjoy the fonctions section in one of the units. When I was doing them in te unit it was really easy for me, but then it came to the finals, i completely forgot about them and couldn’t really figure out what I had to do with f(x). Make sure you don’t miss anything for the big tests.

4. Highlighting key words and definitions are very helpful because I did that for the first two chapters, and then stopped. I realized when I was studying for the mid term and finals that by having the key words and definitions highlighted, it was much easier and time efficient when I was remembering what to do during the chapter.

5. Just do your homework. I know that it’s not in everyone’s best interest to sit down and do math when they get home, but it helps so much. Even if you don’t do all of it, don’t leave your book empty. By at least doing a few questions, it can make all the difference to your understanding and your grade.

# Physics Project!!

in this video, it shows a guy falling down the stairs. this is the concept of gravity. Gravity is an invisible force holing us to the ground. then he missed a step, gravity pulled him down causing him to fall. he is being pulled down at a speed of 9.8m/s because that is the speed of what all things fall at.

this video demonstrates the concept of uniform motion. where things move at the same speed, and never speed up or slow down. they just keep going like this forever. a place that has things moving at uniform motion is in space.

# #15 Graphing project

Raiyah Tyers, so my initials are R.T

these are the plot points that i  used to graph them.

# Mount Vesuvius

above is a picture of Mount Vesuvius. the photo was taken by Melvin .C Shaffer in 1944 ( Shaffer, Melvin C. Digital image. N.p., n.d. Web. )

Mount Vesuvius is a composite volcano  which is active in Italy. Mount Vesuvius is part of  the Campanile volcanic arc which sits on the tectonic plate where the African plate is subducted under the European plate. in the power point we watched in class today, it was all about earthquakes and volcanoes, this one being with an extremely devastating past. subduction is when one plate over laps the other. composite volcanoes are typically found near subduction zones, just like Mount Vesuvius. what happens is that when the magma reaches the surface, gas builds up until there is too much. that is what causes an eruption! the photo is an eruption in 1944. Mount Vesuvius is best known for is destruction of the city of Pompeii. Mount Vesuvius has experienced eight major eruptions in the last 17,000 years.

# #12 Fonctions

Fonctions go hand in hand with domain and range… sorta. You’ll see when we get into this weeks video! I’m sure you will pick up fonctions right away just like i did! IMG_2188-2jn2ngr

# Math #11

today we are going to learn domain and range! How to look at the different types of graphs, the types of brackets, etc.

Domain and range is something I understood right away! Hopefully this video will help you too! IMG_1980-1n6wrsr

# Math week #10 Factor in by decomposition

• Factoring by decomposition is not hard. I thought it was at first, but it’s really not. Watch the video to learn how to do said activity! IMG_1867-1bkrw5j

# Math #9! Difference of squares

IMG_1708-2jbqexr

the différence of squares is a very easy process! Just remember that it has to be a subtraction question because it is a perfect square being subtracted from another perfect square. With practice it gets very easy.
