YOUR QUESTION:

Either I am not understanding this question the way it was supposed to be understood, and made things more difficult for myself, or I am just stupid ouo. I'd like to know your understandings for this question hehe! ^^" (its the first question on the page with the image next to it) sorry for the countless questions!

I think you're dealing with the Pythagorean theorem, no?
(a²+b²=c²)
in this case dougie is known to be in the center of the posts, and jon is at one end of an iso triangle, so the midline (jon to dougie) that divides the triangle forms two right triangles
now you plug in the lengths into the equation
it's been so long since doing this for me all I can think of is cos/tan/sine though?
It may be like
(3x²+x²=2.8²)
(4x²=2.8²) ect

so sorry guys ment to get to this sooner! college has been kicking my butt

THE PYTHAGOREAN THEOREM IS CORRECT!!!!!!
you just need to cut the triangle down the center, which is gives you the values for
I just want to say that this right here (the edit) is completely correct you just need to solve for x then plug in
take the square root of both sides to get rid of the power then do your simple math! <33

for how you solved, you used the info they gave you and the theorem
and for assumptions I say summarize the discussion I scrolled through otl

IF ANY OF THIS DOESNT MAKE SENSE PLEASE MESSAGE ME ILL CLEAR IT UP!!!!!!
A LOT OF THE CHAT HERE WAS GETTING WAY OUT THERE AND WAS A BIT CONFUSING TO DECIPHER DUE TO HOW IT WAS PRESENTED

TYPE OF QUESTION: math
YOUR QUESTION:
so there's a function and I'm supposed to find the vertex of the parabola without graphing it.
the function is: f(x)=-(1/2x+1)^2+1
I know the vertex is the horz. shift and the vert. shift, but I'm unsure why the vertex is at (-2,1) and not (1,1)(using the horz. shift and vert. shift)
Could someone explain it to me really throughly how to solve it and why? Sorry if this seems really easy, I'm bad at math and I have a test on this tomorrow. e-e Thanks for any help!

I'm unclear where it says that the vertex is (-2,1). Seeing this problem, this is what I think:

So the vertex form is y = a(x - h)^2 +k

The vertex of a function comes from the variables (-h,k). In your equation, h = 1 and k = 1. Therefore, your vertex would be (-1,1), since you take the opposite of the h term.

Bobkitty, I'm so sorry but I only ever did a couple of those types of problems, and that was several years ago. I'm not honestly sure how to solve that problem either. I would say to ask your friends about it, and if they can't help, ask your teacher. If the teacher is any good, he or she take the time to help you if you don't understand something.

EDIT: I think M00N is correct, the math looks right and that assumption can be made with the information given.

also want to throw in that this is correct you don't need the edit :)

in this case dougie is known to be in the center of the posts, and jon is at one end of an iso triangle, so the midline (jon to dougie) that divides the triangle forms two right triangles
now you plug in the lengths into the equation
(3x² + x² = 2.8²)
(4x²=7.84)
divide both sides by 4
(x²=1.96)
take the square root of each side
(x=1.4)
just one more step! since the net is 2x wide, its width= 2 times x = 1.4 times 2 = 2.8 m
and theres your answer and how to get it!

Note, when doing the pythagorean theorm, it is the whole variable (a)^2+(b^2=c^2
So it would NOT be
3x^2+x^2=2.8^2, if would be instead,
(3x)^2+(x)^2=2.8^2
So it would be
9x^2+x^2=2.8^2
Which would be simplified go be
10x^2=2.8^2
10x^2=7.84
X^2=0.784
X= 0.885
X= (rounded to) 0.89

And to find the full width, you have to multiply that by two, so
0.89×2= 1.78
So the answer is 1.78m long.

Moon, your concept was correct, however remember when you use the pythagorean theorem, note that the A variable is talking about the whole thing, so we must remember to put brackets, and square the WHOLS thing. C: dont worry though I've made that mistake countless times...so yea I learned haha!

ah yes I wasn't sure about that
I had considered that concept but I didnt think to square the 3 separately so I figured it must not be that path
summer vacation=total brain dump I swear
thank you for helping us!

Ha-ha! No worries moon! We all have our misconceptions at times! I totally experienced this multiple times for. And then got shrekrd by my teacher hahaha!

Study Tips!
Because I should be studying right now, I thought I would share with you some of my study tips!

1. Do not procrastinate like I am right now. Due to my procrastination I have to finish a whole big book in 5 days, take 10 more pictures of nature, write a 30 page thingy-ma-bobber, and much much more. So please, DON'T DO IT! IT'S BAD TRUST ME

2. Make it fun for you in some way. *not implying that studying is fun either way* Turn on some music (I know they say not to listen to music with words, but it helps me a lot to get motivated personally.), get a snack, or even just some colored highlighters to make it a bit more fun!
-when I was little, I would turn cleaning into a game, so I try and think of this the same way-

3. Find out what kind of learner you are! Visual? Draw or find something that will help you memorize! Auditory? Listen to what you need to memorize over and over, or try and say it over and over to yourself to keep it in your mind. Kinesthetic? Find something you can interact with to learn (pop up pages, etc.)

4. If possible, find a study friend or someone who can come over. I know this isn't possible for everyone, because it isn't for me >.<

5. If you really find yourself unable to study at home, try going to the library or something! Most libraries have desks set up where you can do whatever work you need to, and you can usually bring your laptop and everything for free wi-fi, etc. I remember once my mom had to do something at the library, so I looked around for a while, then I sat down for about a whole hour and did homework XDD

6. Find what motivates you! Is it an inspirational quote? Is it a reward at the end? Set up something that will help you get motivated, such as "If I finish this page of math, I can get this piece of candy" or whatever it might be.

7. If studying for a test, make practice sheets and make it like you're really taking the test at home. See what you got wrong one hour, do it again later after studying a bit more, and continue that until you've got it down. I have done this COUNTLESS times, and it has helped me so so so much.

8. Don't overwork yourself. If you need a break, take one (within moderation). If it gets to the point where your brain is no longer retaining information, it's time for a quick break to clear up some of the thoughts going on.

9. Make it easy for you. If the teacher is making things confusing, don't be afraid to step it back a bit and try it a different way that makes it better to your mind. I have been told not to do it in math, but it really helps me a lot.

10. Get into a routine of studying. I have a problem with this, but I'm working on it. Try and set a time every day that will work for when you can study or do homework. It'll set your brain to know when to study!

Thank-you for your tips! C: I will post it up on the front page asap!

6. Find what motivates you! Is it an inspirational quote? Is it a reward at the end? Set up something that will help you get motivated, such as "If I finish this page of math, I can get this piece of candy" or whatever it might be.

All of these tips are good, but this especially is a really good one (as long is you don't cheat).

Man, I used to put chocolate chips on my math sheets every two questions or so, so when I finish that question, I can pick them chips off and satisfy my undying love for chocolate ouo

Any boody have any more questions?
