Math Game

[Ondrej Kapal]

I did your (umm that thing) in school so I didnt manage to send how I solved it, so now I did

I normally dont use that much of notes, but I did exceptions for you

 

[Aaron DeMarre]

Yup, the good 'ol quadratic equation. Thanks for showing your work! :good:

 

[Ondrej Kapal]

will post somethig tomorrow

 

[Ondrej Kapal]

find graph y=|x^(-5) - 3| and its properties

 

[Dave Stephenson]

Well, I was holding off to see if someone else would solve this one since I didn't want to come up with a new problem, but to move it along here is the answer

ah crap I knew it was quadratics but i couldnt remember the formula I needed to build from the points. nice reminder that is a long while since I went to school.

 

[Ondrej Kapal]

find graph y=|x^(-5) - 3| and its properties (on paper scanned or by excel)

ok if you would just find intersection x,y and saturation point it will be enough - this can be calculated very easily without painting anything and properties also can be done - nothing to paint or work with excel

 

[Ondrej Kapal]

I gues I would post something else

just find solution

Is anyone going to go for it, or do we move on? I am too young to do this

Wow, it's took nearly 3 years for anyone to post here. I thought it was a new game!

I got 101, calculator says 181.4984472? Pretty sure I'm wrong... Maybe I'm supposed to simplify, I really don't know. I seem to recall doing things like this not too long ago, but I've forgotten already

Btw, Ondrej was last seen in July, so even if someone does get it right, we may never know

Use Google?

 

[Alexander Macdonald]

All I'm getting now is 189.5. maybe that is the answer

 

[mystaaRS]

Check Google...

 

[Alexander Macdonald]

I've checked just about every calculator there is. Maybe I've misread the point of the question, but since Ondrej Has been away for a while, I might try and think up a new one

I think that you first do the root of 5 a proper number (~2.2) then you multiply with 2 (~4.4), add 9 (13.4) and power elevate with two (179.56)

 

[Alexander Macdonald]

How many different answers are there?

2×√5 is the same as √5×√4 which is the same as √20. If you added 9 to that you get 13 point something and squaring that gives you 181.5. If you square both numbers seperately and add them together you get 101 which is a much nicer number but I don't think its right

Alex, put one

lol, math in freetime... I guess i am in the wrong forum?

You are in the perfect one

I'm on a phone right now, so I can't really post a question right now as this forum is a bit awkward on a phone

Does anyone else accidentally click on a rating when using a phone. I've accidentally disliked some posts before
