Question

hey guys my son needs help with this. http://blogs.spsk12.net/1051/files/2012/12/Chap-4-Project.pdf
i have never seen anyhtign like this before and ive been outa school for years now could yall give me an example of this he only needs to do activity 1,2,3 thanks i reeallly need to help him on this its due in the morning

Answer 1

id really appreciate this guys

Answer 2

ill try my best

Answer 3

thansk so much man i really appreciate this

Answer 4

so i saw your messages and what is interesting to me is does it matter how far you stand from the target.

Theory:
the parabolic arc is a curved linear function so how wide it is also plays a key function with how the parabola will look.

Any clues if distance matters would be nice, btw i am a college student and i have never seen such a interesting assignment... This is an Alg 2 assignment based on the link you sent me so i am trying to figure out a non pre calculus approach...

Answer 5

it dont matter how far u stand from the target

Answer 6

hmmmm.... assignment is too simple... i am not sure but for assignment 1 you can say that the possible curves change due to the fact that if you stand higher there is less of a sharp curve as if your were sitting....

Answer 7

i have never encountered these activities for a math class.... and i graduated class of 2013....

Answer 8

well i guess according to the papaer you have to write something about a y=ax^2+bx+c

Answer 9

Yeah i am sorry i have no idea... try bumping up your answer to see if anyone else has an idea cause maybe i am missing something to connect this but i don't know how to figure that out :( I am soo sorry

Answer 10

you got no idea aboiut this? i need this help man
\

Answer 11

i really dont know... i start thinking about amplitude and other advance math and physics concepts which shouldn't be used in an Alg 2 class setting... :/

Answer 12

alright a lot of people are veiwing this but nobodies replying so o well

Answer 13

seems like your son has the rare activity based teacher... my alg 2 teacher it was all just numbers and maybe a word problem, but this is very hands on :/ i have never done activities like these except like in physics but we would use gravity= 9.8 for example as well as distance and other factors that aren't clear or were voided in these problems

Answer 14

yeah ight well thanks for the help

Answer 15

Part 1 is fairly simple. It's just measuring stuff and drawing. I don't know I can really help with that.

So anyway. Part 2 is about finding the equation to a parabola. We have a situation like this:

Answer 16

That's a terrible drawing. But the basic idea is that we (sort of) have three points so we can find the equation to the parabola.

Answer 17

thanks man do you know what the equation wil be for number 1?

Answer 18

What equation? It's not asking for an equation, just a sketch.

Answer 19

it says on the paper its supposed have something about y=ax^2+bx+c

Answer 20

and you got any ideaq on number three

Answer 21

I think the \(ax^2+bx+c\) stuff is about activity 2. That's where you have to find the equation for a parabola.

Number 3 is telling you to use a feature on a calculator.. so just do that, I guess? :)

Answer 22

we dont have one of them calculators so i have no clue what to do on it

Answer 23

what does it mean to find the linear and quadratic regression for this data?

Answer 24

http://easycalculation.com/statistics/regression.php

Answer 25

It means find equations that model the given data, I think.

Answer 26

whats the data i need to put in the calculator?

Answer 27

It's given on the sheet...

Answer 28

which one

Answer 29

The only one given.

Answer 30

never mind i see it so i just put that data into the calculatopr u gave me and itll give me the answer?

Answer 31

Hopefully!

Answer 32

it aint working boe

Answer 33

You did something wrong, then. I just tried it and it worked fine for me!

Answer 34

on activity the the chart that says weighin grams and weight in inches is the chart i need to take the data from correct the grams is the x and the inches is the y then i hit calculate correct?

Answer 35

Yes. You'll need to click "Add More" several times to make room for all the data, of course.

Answer 36

i did that and i hit calculate and it did nothing

Answer 37

I dunno then.
It gave me a regression equation of \(y = 3.513-0.015x\)

Answer 38

is that all it gave u? it must not work on my laptop

Answer 39

It also gave me a slope and y-intercept but that's included in the equation.

Answer 40

can you give all the boxes it gave u please

Answer 41

I already did! Well, and total numbers 5, but you knew that.

Answer 42

ok well thanks for the help man i appreciate it

Answer 43

No problem. :)

Answer 44

i am so glad that got sorted out and you got the information to help your son :)
