  4. hey Mrs. M. For the entertainment part question two, when you say what sort of function might modelt this gragh do yu mean rule? like y=ab^x?

  5. oh an for the investagation, do you want us to do the problems on thoose pages or just review them

    ReplyDelete
  6. J.W.: the pages in blue are for the investigations...and yes, you must complete them

    M.P.: You would tell me if it's a linear or exponential function

    ReplyDelete
  7. Hey Ms.M:) umm i need help with 8b on page 341. um the question is: Experiment with your calculator or computer software to find a function of the form y=b^x (where x is time in days) that matches the pattern in your table.

  8. Um not rushing you but i still need help

  9. J.J.W.: you should have seen my face when I read that last comment, lol...but anywho....you need to enter everything from your table and do an exponential regression (the calculator will do everything for you)...just like we did yesterday for the checkpoint quiz...let me know if you need the steps

    ReplyDelete
  10. i need the steps and i dont get number 13 on page 311

  11. is 14 15 16 the same im so far up the creek a paddle wouldnt help, so will you? im lost

  12. Steps for Exponential Regression:
    1) Go to "STAT", then choose "Edit"
    2) Enter your values from the table into L1 and L2
    3) Go back to "STAT", scroll over to "CALC"
    4) Scroll down to #0 ExpReg (Exponential Regression)
    5) Press "ENTER" twice...you will see what you need to plug in for y = ab^x

    Steps to see a Scatter-plot
    1) Enter your values from the table just like in steps 1-2 above.
    2) Go to "Y=" and clear everything out
    3) Make sure Plot1 is turned on
    4) Go to "Zoom", choose #9 ZoomStat (this will show you the shape of the graph so that you know which regression to do...you will need to do this for most of the problems you asked about)

    Let me know if this helps at all...

  13. 14-16 are all about the properties, so you need to do the investigations first...but don't worry so much about the properties because we will do a lesson on those together to make sure everyone understands

    ReplyDelete
  14. umm okay supa slash face status im real real lost but umm yeah

    ReplyDelete
  15. Do as much as you can with the other problems and we will talk about the properties in class...relax! (I can just imagine the face you're making)

    ReplyDelete
  16. haha i wish you would see it (the supa mad stressed mad some more face) how u gon say relaxx when its due tomorrow!?!

    ReplyDelete
  17. Your investigations and homework are due at the end of class, but your presentations don't have to be ready until Monday...but I'll just go ahead and tell you my plan...I'm going to just go around and check the homework...you all will be able to keep it so that you can put the finishing touches on it so you can be ready to present next week

    ReplyDelete
  18. um im starting to feel stupid. i dont understand how to do the (3/5)^3= 3^x/5^y...wtfeezzy is this stuff? my sisster dont even know how to do this stuff and she just graduated highschool last year

    ReplyDelete
  19. Don't feel stupid...some people have learned about the properties in other math classes and others haven't...so like I said before, don't worry about that part...just finish the problems from your other 2 categories. We'll go over the rest of the stuff as a class....DIDN'T I TELL YOU TO RELAX!!! :)

  20. Hi Ms. McCullough, What is an equivalent exponent?
    Thank you, Benjamin Raposa, 4th hour.

    ReplyDelete
  21. Hi Ben! An equivalent exponent is the answer you get once you simplify the expression using the properties we talked about the other day. If you're doing the investigations or homework, there are different directions for each of them, so if this doesn't answer your question, let me know the specific problem you're working on.

  22. Hi Ms.McCullough. What are your tutoring hours in the morning, in reference to ewhen I would need to arrive at school? Thank you, Benjamin Raposa, 4th hour

    ReplyDelete
  23. ay this i s cameron i dont get how you got the numbers for the home work the entertament one and its on the last page yea so i see what it says and im just confused on the total gross please heeeeeeeeeeeelllllllllllllllpppppppppppp mmmmmmmmmmmmmeeeeeeeeeeeeeeeee (country sound)

    ReplyDelete
  24. Ben: I don't have formal tutoring hours in the morning since we have our daily staff meetings, but I usually have some time from around 10-10:30 before class starts...the best time is during lunch or after school on Tuesdays or Thursdays...so it's up to you whenever you want to stop by. Also, I mentioned that there are student tutors. I can give you more information about that if you're interested in that too.

    Cameron: The total gross means the total money that the movie earned (on the y-axis), so they just want you to see which 2 movies Pirates of the Caribbean will be in between (that means which movie will earn a little more money and which movie will earn a little less money)...let me know if this helps at all...

    ReplyDelete
  25. but how do you get the groos cuz i know you add the starting gross to the total but i dont know or get it

    ReplyDelete
  26. My phone is dead, but I think you're thinking about the question too hard...They already give you the total gross on the graph...talking you through it would probably be confusing too, so just come see me first thing in the morning before class starts...if you don't have everything finished by then, I will let you present on Wednesday, that way if you need extra time we can work on it at lunch. Does that work for you?

    ReplyDelete
  27. the last page on the enterament thing

    ReplyDelete
  28. I have a Qustion.... I was at a funeral to night and just got back and im not done with my part of the project and i wont be able to finish it to nigh... so will i get points off?

    ReplyDelete
  29. Just finish it tomorrow and you and Shane can present on Wednesday since we won't get through everyone tomorrow.

    ReplyDelete
  30. Hi Ms. McCullough. Do the rules on the direction as far as what needs to be included apply to the exponent investigations as well?Thank you, Benjamin Raposa, 4th hour.

    ReplyDelete
  31. um i gosta question!(3/5)^3 i cant find no example for dat...how you do it???
    -kid that goes hard

    ReplyDelete
  32. okay... in the second investigation for properties.. im confused on number 1... (3/5)^3 = 3^x/5^y... its on page 332

    ReplyDelete
  33. Ben: You only have to answer the questions like regular homework for the investigations...the additional rules only apply to the activities that were not in the book.

    Joclyen & Auri: The property is called "power to a quotient"...it's just like the "power to a product" where the exponent is applied to each number...so your answer would be (3/5)^3= 3^3/5^3, and you would tell me that x=3 and y=3....does that make sense?

    ReplyDelete
  34. And just for the record "kid"...you WERE rushing me...I do have a life, ya know!

    ReplyDelete
  35. so basically whatever the exponent is... thatll be x and y? so like for part b... (c/n)^2 = c^2/5^2?

    ReplyDelete
  36. alrighty... thanks(:

    ReplyDelete
  37. i know you gotta life and i do too:)but the math work is holdin me up :/ And i aint mean to rush U cause i coulda been worsum and continued posting until you replied:) (i really wouldnt do that)... lets just say i aint mean to "rush" u...ya know! (im unhappy now just for a record)
    -the kid that still dont get how to do the problem

    ReplyDelete
  38. It's ok...I'm not mad at you:) But what don't you understand? You just have to distribute the exponent to the numerator and denominator...didn't we do a problem like that earlier today? or maybe I wrote that on somebody else's sticky note...

    ReplyDelete
  39. okay glad u aitn mad that was shanna stick note like how do you do it like do you distribute first then divide or like divide den distribute cause i dont know
    -kid thats happpy u not mad lol

    ReplyDelete
  40. For that specific problem, they just want you to give the value for x and y...that's it, that's all...you're thinking about it too much....you would only go further if they asked you to simplify it or something...

    so the problem is (3/5)^3=3^x/5^y...the property tells you to distribute the exponent to the power of the numerator and denominator....so it ends up being 3^3/5^3, so you would say that x=3 and y=3...THAT'S IT!!! DO NOT GO ANY FURTHER!!!

    BUT if you want to know how to simplify it...3^3=27 and 5^3=125, so your final answer would be 27/125.

    Does this make any sense?

    ReplyDelete
  41. thanks i think it dont make as much sense because i cant see you and the sticky note but i think i got it
    -kid that likes stcky notes better than blogging

  42. Ms. McCullough,
    My partner did not do anything on the project and I would feel uncomfortable firing her so I got all of the work dumped on me. What do you want me to do because I am not ready to present to you tomorrow because only half the work is done.

    ReplyDelete
  43. Come talk to me before 1st hour, but go ahead and prepare your presentation on the half that you completed...we'll worry about the rest later.

    ReplyDelete
  44. Thank You soooo much Ms. McCullough that helps A LOT!
