The variable in this equation is on the bottom of the cosine equation so that means we have to switch the two around and then put the variable on top of the cos number. Then divide as intended
This is also a cosine problem but this time all we have to do is put the x on the opposite side of the equation and then turn cos into an inverse cosine and do cosine 5/6
The variable is on the top for this one as well so all that has to happen is the inversion again as the problem anove
In this first video it explains acceleration. We see that the bus in the video speeds up with a continuous sound, and it slows down with a harsher sound. As explained, the bus speeds up, because of the change of acceleration, and there can be positive, negative, and zero acceleration. The bus slowing down is called de acceleration. Acceleration can be calculated by change in velocity divided by time. This allows us to calculate the rate of acceleration.
In this second video we see two men racing. They both are going the same speed and they are staying at the same rate of velocity, so they are racing in constant velocity. Near the end of the video they both take a fall, but one of the men gets up and continues on racing while the other man is left laying on the ground but eventually gets up and walks back towards the start. Not only is this an example of constant velocity but it is also and expample of displacement. The man who continues on will have a greater displacement and a greater average velocity based on he kept moving and the man who turned around went backwards on a negative path back to his zero starting point.
in this triangle I have the A angle, and side AB, which is 42.2. We are trying to find the variable b on the AC side. After labeling I was trying to find the adjacent side. To do this I had to use COS. I had to go cos25 x 42.2 because the variable is on the top. the answer I got was 38.2.
in this triangle it was cos again and my formula was 50.2 over cos30. I had to reciprocate the variable and create a division question. my answer was 57.96
this triangle was cos once again, and in order to complete this I had to do cosX = 5 over 6. in order to isolate the variable I had to move X to make cos-1 (5/6). this gave 33.55
7 o’clock on Tuesday morning and my brand new iPhone 6 is sitting on my bedside table. I’ve had this phone for almost 72 hours and the slow motion tool is basically all I’ve used. I still have to get up, and my alarm clock reads 7:06am. I get dressed and head downstairs for some Eggo waffles. My mom doesn’t have the toaster out like she normally does; I take it she hasn’t even gotten down here yet. My phone buzzes; I pull it out of my jean pocket and head to the bathroom while reading:
“ Hope your new phone is nice, love dad :)”
I smile, and put my phone back in my pocket. Just as I get in the bathroom, I freeze when I hear a loud sploosh and a clank from behind me. I look down, and- oh no. OH NO. My BRAND NEW iPhone 6 with black and pink sparkles on the case is drowning before my eyes, and the only thing I can think of doing is just going in and reaching for it. My hand is soaking; I’m almost in tears, I pull out a bag of rice, zip it shut, and shove it in my purse before turning around and seeing my burnt waffles. I hear my sister from upstairs asking to use a curling iron. What?
“I don’t HAVE a curling iron!” I yell back.
“GOD IM NOT TALKING TO YOU EM!” she shouts.
“I’m leaving in ten minutes ladies!” My mom states, for the third time in 20 minutes. My sister and I run around until we are ready. I think about my phone for the whole day until about 2:00; when I decide to call my mom and tell her the news. The phone call goes a little something like this:
ME: Hi mum, how are you?
Mom: Fine, why are you calling? What happened?
E: Oh not much. Hey, my phone has been acting weird, I think I’m going to go to the Bell store after school to check it out.
M: WHAT? It’s three days old! What did you do?!
E: NOTHING! I just maybe dropped it in the toilet this morning and maybe I shoved it in some rice and came to school with a bag of jasmine rice with a hint of phone…
M: Okay, go to the Bell store and find out if you can fix it. YOU are paying for it.
E: Okay, love you.
M: Mhmm. Love you. *CLICK*
By the tone of her voice I knew I was in for it. It wasn’t that sweet tone of suggestion, it was that drill sergeant command tone that could make someone “have an accident,” You know the tone. As soon as the bell rang I was already on the way to either my end or my savior. Sweating and panting from running across town, I bust into the Bell store; the clerk recognizes me. GREAT.
“Well dear, your warranty is activated thankfully”
“AWESOME! That means I can just get a new model right now right?”
“Not exactly. We changed the warranty a few hours ago, so now all our customers have to pay 250$ for their new phone with our warranty rule,” She smiles.
“What? I though our warranty was if you break it, you get a new one, no problems!”
“Well now it’s: you break it, you buy it,” I almost jumped across the counter to straighten her out, but she smells like vanilla cupcakes, so I’ll let it slide.
“Okay, thank you for your help,” I turn around as the reality sets in: I have to run away. Or I can face my problem. At this point, running away seems like the better option. The bus ride home is agonizing, because I can see my mom at her desk furiously texting on her Android to my step dad about how ridiculous I am. I’ve been biting the inside of my cheek for about 20 minutes; I taste a little blood, so I stop to observe the beautiful landscape beside me. Whizzing by at 70km and hour, I soon realize I will not be seeing it again, so I cherish every passing moment as I await certain death. (Not literally, but you get my point.)
“I can’t even speak right now,” my mom says quietly.
“I am so sorry, I will pay for everything,” I promise. A few minutes pass filled with awkward silences, death stares from my mother, and glimpses of my death, before my step dad walks in and takes my mom upstairs to talk this through with her. 10, 20 minutes go by; Dave comes downstairs to console/teach me.
“There isn’t much I can say to make you feel better, so here it is: you broke your phone after having it for three days. You tried to fix it by putting it in rice and taking it to school: good. You tell your mom what you can do to fix the situation, she gets mad, you get scared, and now we are here. Give her some time, to think. All you can do now is wait. You gave her all the solutions to the problem, and she doesn’t have a punishment, because you tried. That’s what counts.”
“Now what?” I ask.
“Nothing. Not on your end at least.”
Days pass and my mom and I come to the agreement that I pay for the new phone, I do not touch my phone in the morning until I am about to leave, and nothing more. Let me just say that my chores were DONE every day, and the house looked great the next week. Taking your phone into the bathroom is very unnecessary, and what is even more stupid is putting it in your back pocket. DO NOT go to the bathroom with your phone. You don’t need it all the time. Try putting your phone down once in a while, and you will avoid problems in the future.
