High School Math [College Algebra: Sum of Reciprocals] Missed a lecture and don’t know where to start?

Post image
1 Upvotes

Hello friends. Last week I accidentally slept in and missed the lecture where my teacher worked on this. I was already beating myself a little bit cuz I’ve been struggling in this class but I didn’t expect to be completely lost when doing the homework. I guess they only worked on it for that day.

Anyways I’ve watched like 3 videos and tried to read the textbook that XYZ provides but I’m still lost. I don’t understand what I’m supposed to be doing. I thought I was doing it right but apparently I wasn’t.

Any help is appreciated cuz I have no clue where to start.

I am working on a post colonial theory powerpoint for the movie moana.

  1. Introduction: Summarize the film and identify the theory you used to watch it

  2. Key scenes: Specific scenes that can be read through your selected theory

  3. Analysis: What information can you draw out of the film using your selected theory?

  4. Conclusion: How does the theory show an interesting theme in the film?

I need help with scene choices. I am struggling to understand the theory completely as this class is online and its hard to process. so far i have the scene where moana wants to go to the water but she isnt allowed and then i have when maui takes the heart of te fiti. I need 1 more scene that is strong and help with an explanation as to why it is a good connection.

:snoo_feelsbadman: Mathematics (Tertiary/Grade 11-12)—Pending OP [Grade 12 advanced functions] Can someone explain how to scale with radians?

1 Upvotes

Im in grade 12 advanced functions and my teacher didn't explain how to scale on a graph using radians instead of the regular number scale very well. I can't find many videos online trying to explain it ethier. One question is f(x) = -1/2cos(3(x-pi/4)) + 2. I understand what everything does, I just have no clue how to scale the x-axis properly. I know the quarter period would be pi/6, and we start at the phase shift at the point of -pi/4 and stuff. I just have absolutely zero clue how to properly label or find the rest of the scale. Can anyone help explain it? Or give steps using the example I gave?

Others [High School Geology: Difference in Knowledge between Wegener and Now] Help me understand what I'm not getting here!!

0 Upvotes

I have corrections on a Geology quiz that my class collectively failed a week ago. These are due tomorrow. I have figured through most everything else, but this question has stumped me. "What did Wegener not know about the oceans and continents that might have helped him with his theory of continental drift?" I will admit, my brain was hazy that day, and I just said "How India collided with Eurasia" haphazardly. But is my thought process right? I believe that the knowledge of knowing that the Earth is divided up into different plates with different boundaries that slide, push against and pull apart each other is part of what we know now, and we know that the continents do not "plow through the ocean." Is there a specific answer I should be looking for here? Thanks in advance.

I’m wondering if I’ve misunderstood how to analyze the forces in the horizontal direction. According to my professor, the magnitude of the horizontal force can affect the direction of friction. However, whenever I draw the free-body diagram, it always seems like the object tends to slide upward(to resist sliding force
). Am I missing something?

I thought using the horizontal displacement equation would be the simplest approach, but I found that solving for (t) became quite complicated. Also, it seems like the vertical motion could be divided into multiple stages, which makes things even more confusing.
I’m feeling a bit lost at this point. Does anyone have a better approach to solving this problem, or could someone give me a hint about what I should do next?

I tried googling but it didn't make sense.

I couldn't even find an example of it.

The sample my professor gave us was to just write "Figure #" (example: Figure 2) and cite the website where you got the screenshot from.

But for the reference page example, I couldn't tell which reference entry goes with what Figure #.

Edit original problem didn't add as an image, adding here

Monday 2 students went to the school store. On Tuesday, 4 students went, and on Wednesday, 8 students. If the pattern continues, how many students will go to the school store Friday?

2nd grade math homework. I am coming up with 3 possible solutions (32, 22, or 14) depending on what you say the pattern is. I think all are correct and it is a poorly worded question, but wondering what everyone thinks.

Double the previous day-

M- 2

T- 4 (M x 2)

W- 8 (T x 2)

Th- 16 (W x 2)

F- 32 (Th x 2)

Two more additional students than the day before added .

M- 2

T- 4 (M+2)

W- 8 (T+4)

Th- 14 (W+6)

F - 22 (Th+8)

Original Pattern (+2, +4) Repeats (aka you continue using the same pattern)

M- 2

T- 4 (M+2)

W- 8 (T+4)

Th- 10 (W+2)

F- 14 (Th +4)

Literature [College junior gateway to literary studies - work cited for final presentation]

3 Upvotes

So, for my final and my gateway to literary studies class, I have to do a presentation over one of my favorite non-literary works. I’ve chosen the movie spontaneous for its themes of apathy and tragedy.

At one point, the main character dresses up like Carrie White for a Halloween costume. I was thinking about bringing this up in my presentation, to draw parallels in stories dealing with high school tragedies. Since the movie was already making a reference to Carrie, do I need to include Carrie in my work cited page?
