Calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents.

OpenStudy (anonymous):

i believe the average would be 52 so 52 represents y

OpenStudy (anonymous):

@ayeedomo what do u think even guess if u don't know

OpenStudy (ayeedomo):

ok. Thanks for your help :)

OpenStudy (anonymous):

k by and np

OpenStudy (shamim):

Rate of change of velocity=change of velocity/ change of time

OpenStudy (anonymous):

did my reply help at all ? just asking

OpenStudy (ayeedomo):

not really :(

OpenStudy (shamim):

Change of time=3-1=?

OpenStudy (ayeedomo):

= 2 ? @shamim

OpenStudy (shamim):

Now can u tell me the change of velocity=?

OpenStudy (ayeedomo):

4?

OpenStudy (shamim):

So rate of change of velocity=4/2=?

OpenStudy (ayeedomo):

= 2 again?

OpenStudy (shamim):

Yes!!!

OpenStudy (ayeedomo):

Yay! :D

OpenStudy (shamim):

Wt will b the unit of rate of change of velocity

OpenStudy (ayeedomo):

wt?

OpenStudy (shamim):

4 mile/hour/2 hour=?

OpenStudy (ayeedomo):

I'm starting to get confused..

OpenStudy (shamim):

Ok, i wanna help u

OpenStudy (shamim):

U know change of velocitu=4mile/hour Right?

OpenStudy (ayeedomo):

hmmm I'm trying to figure all of this out here...

OpenStudy (shamim):

Change of time=2hour

OpenStudy (ayeedomo):

ok

OpenStudy (shamim):

So rate of change of velocity=4 miles/hour/2hour=2miles/hour^2

OpenStudy (shamim):

Did u get it ?

OpenStudy (ayeedomo):

So the average rate of change would be 2 miles per hour?

OpenStudy (shamim):

2 mile per hour square

OpenStudy (shamim):

Do u know abt acceleration

OpenStudy (ayeedomo):

where does it mean being squared? And maybe but I don't think so XD

OpenStudy (shamim):

It means mile/hour/hour

OpenStudy (shamim):

Now i m in bus

OpenStudy (shamim):

So typing slowly

OpenStudy (shamim):

Sorry

OpenStudy (shamim):

U know velocity means rate of change of displacement

OpenStudy (ayeedomo):

I kinda get the squared thing now but it's still a little confusing lol.

OpenStudy (shamim):

U know rate of change of acceleration means rate of change of velocity

OpenStudy (ayeedomo):

ohhh yeah

OpenStudy (shamim):

Ok tell me 1/x divide by x =?

OpenStudy (shamim):

(1/x)/x=?

OpenStudy (ayeedomo):

hmmm. 1 or x?

OpenStudy (shamim):

No

OpenStudy (shamim):

(1/x)*(1/x) Right?

OpenStudy (ayeedomo):

aw

OpenStudy (shamim):

=1/x^2

OpenStudy (shamim):

Again tell me (1/3)/3=?

OpenStudy (ayeedomo):

oh geez this is getting more confusing.. But 1/3 = .33 right? /3 again would be... .1?

OpenStudy (shamim):

Try it by your calculator

OpenStudy (shamim):

.33/3=?

OpenStudy (ayeedomo):

.11

OpenStudy (shamim):

Correct!!

OpenStudy (shamim):

1/9=?

OpenStudy (ayeedomo):

.11111111

OpenStudy (shamim):

(1/3)/(3/1)=(1/3)*(1/3)=1/3^2=1/9=.11 Right?

OpenStudy (shamim):

I will b more efficient after 30mins

OpenStudy (shamim):

Perhaps i shall reach my home then

OpenStudy (ayeedomo):

@Lovelarap @ganeshie8

OpenStudy (anonymous):

What level is this?

OpenStudy (ayeedomo):

level?

OpenStudy (ayeedomo):

Algebra one I think

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

It think i remeber how to do this...

OpenStudy (anonymous):

So x=1 is 52 and x=3 is 56, right?

OpenStudy (ayeedomo):

yes

OpenStudy (anonymous):

So what (i think) you should do is minus 56 from 52 and divide it by 3-1.

OpenStudy (shamim):

The problem is mile per hour square

OpenStudy (ayeedomo):

I get it now! :D

OpenStudy (anonymous):

Then that's great!

OpenStudy (ayeedomo):

Thanks for your help!!!!!!!!!!!! :) @Lovelarap @shamim

OpenStudy (anonymous):

your welcome

OpenStudy (anonymous):

bye
