From step one to eight, we saw three energy transfers, starting with magnetic when the magnetic lamp hit the magnet on the tissue box. Second the mechanical energy with the roll of tape hit the books and they fell over. Last the gravitational energy when the gum ball rolls down the measuring tape.
It begins with Marwa dropping the ball onto the wedge, it rolling to hit the lamp, the lame will then move forward to connect to the magnet that is connected on the tissue box, the tissue box will be pushed over by the force of the lamp, causing to hit the roll of tape, the roll of tape then will hit the 4 books, they will fall in order and it hit tape measure, it move move slightly cause the ball to move down the measuring tape into the gum ball machine.
I am going to show one of the many ways to take out the GCF in a polynomial expression.
When you see your initial expression, you wont to ask what is the biggest number I can take out of all of the numbers? You can take out 5x from all of them… Put it on the side of the box. Then what multiplied by 5x is going to give you the numbers inside… These you put directly over the number in the box. Once found you have all the factors of what is inside the box.
This week was factoring polynomials and atbthe beginin it was a lot to take in but by the end I think i got the hang of it.
It really helped when Ms.Burton showed us we can factor usin an Area Model and it was a lot easier for me.
I have drawn out the steps to find the factors of an expression:
This shows the first step, you are given an expression…
(What i’m showing will only work if it looks like this; x to the power of 2/ squared and the middle is a number followed by x and then the last just a constant term or a number with no variable or degree.)
the next step is to list the factors of the constant (in yellow.) then find the one that fits best for the sum of the middle number. place the x squatted in the top left and the constant in the bottom right box then the two numbers that add to 21 in the remaining.
Solve for what the highest number or variable is that you can take out of each two boxes. I have shown arrows and then the answers.
Now the numbers on the outside is your answer, all the factors of the first expression. Therefore your answer is….
Knocking at the door he ran down the stairs, collected himself and opened the door. With a deep breath he invited the three police officer’s in to talk. He place three chairs in the exact room the fresh cut up body rested under the wooden planks. He acted cool with all of this. Slowly a sound grew louder in his head. It was the heartbeat, the heartbeat he claimed to be the old mans. Louder and louder he began to go insane. He began cursing, he raved and he foamed. He through the chair to the side ripped the wood planks up, yelled: “HERE, HERE!” The body was shown to the police officer’s and they knew, the knew the truth; this man was criminally insane. The three officer’s soon clenched cold, metallic and heavy handcuffs to the crazy man’s wrists. He would be locked up for the rest of is life.
Week 8 was continuing on from last week when we began Trigonometry, this week was just an addition to the lessons. We looked into how to find missing angles using Trig. It took me longer to figure out than any other thing for this unit.
In both shade of blue you have the BASICS. A right triangle, a missing angle, the measurements 30 m and 12 m. In red I wrote ‘What I Know’. I can easily find all the sides if I have an angle and a right angle. I labeled each side along with L M S witch tells me normally the hypotenuse is the L / Large as it is the longest side, and where ever the reference angle is, directly across from it is the M / Medium side that is exactly the same rule for finding the opposite side. That leaves the adjacent side leftover to mark S / Small. In black there is the equation to solve for the missing angle, in this case you only have the numbers 30 and 12 and once you have labeled their sides you use SOH CAH TOA and solve. In this case I used sine as i had labeled and found out that the hypotenuse is 30 m and 12 is the opposite side. Once I plugged them into the equation for sine, I found that I didn’t have the angle so using algebra knowledge you have to get theta by its self. In order to do that you have to use INVERSE SINE. You can do this for all, cosine or tangent. and just right it with a negative one as I did in the photo. Hint: There should be a button on your calculator! I got the result 24 out of all of that! In green I added a hint, that symbol thats in the spot where the angle should be is a greek letter called THETA. It is used a lot in math especially in angles.
In Math 10 this week we started Trigonometry. It is pretty straight forward one you have labeled correctly. I will be demonstrating finding a missing side length using Sine, Cosine, or Tangent. Keeping SOHCAHTOA in mind. I have created a video that will show step by step how to solve for a missing side length.
In the short story “The Watch” by Elie Wiesel, he wrote this journey to take us through his upsetting, yet motivationalodyssey as a survivor of a Nazi camp during WWII. Elie was born and lived in Sighet, Romania, he was raised following the Jewish religious beliefs in a ghetto area. Forced to live in this area, Elie and his family still manage to live the best life they can. Being Jewish he had a bar mitzvah at the age of 13, he received a gold watch: “As for me, my only possession was my watch. (Page 1)” This was a general gift to show the newly made man that he now had responsibilities and had to act more carefully towards the Torah, its rules and laws. Taken to the Nazi camp at 15 he found himself, along with his parents and sister, burying his watch along with all their most valuable or attached items before they left. They buried them in their garden. During the time spent in the Nazi camp Elie, his family and others trapped in this horrible place had the mindset that they would get out and retrieve their past lives. Twenty years later Elie went back to the exact spot in his old garden that he buried the watch and started to dig. Once he found it he reburied it. This symbolized him moving on from his dreaded memories and leaving them buried with his watch: “In retrospect, I tell myself that probably I simply wanted to leave my past behind me, underneath the silent soil, a reflection of my presence. (Page 5)” According to this short story Elie Wiesel recovered from extreme hardship by burring his watch along with horrible memories.
I did awesome on my quotes.
I could work on my image choices and writing sentences that need to be there. Not ‘just beach’ sentences.
