Math Homework

OKay help me out guys and girls, my little cousin needs help and I don’t know how to solve any of these. :stuck_out_tongue:

supppose u have 320 feet of fencing and want to completely enclose a rectangular space what is the maximum area you can enclose and wat are the dimensions?

write an equation that defines a rational function with a vertical asymptote as x=2 and a horizontal asymptote at y=0

Help:blush:

Re: Math Homework

eventhough i am good in math.. but rite now i can’t think of anythin… u gotta apply some kinda formula to dat rectangular space in order to find maximan area and dimesions. i think u would use area of a rectangle..:halo:

and then take a slope of dat rectangular space and write an equation: y=something+b :smiley:

and after dat u r gonna google ver. and hori. asymptote.. okay :smiley:

good luck.

:stuck_out_tongue:

Re: Math Homework

awww I tried google....I guess i'll just let the poor kid down.

:crying: sorry homie

Re: Math Homework

That's okay I know no one wants to help poor old me, I heard cafe members were nice so I thought I would check.

Re: Math Homework

dimension = length 20
wi= 16

max= 320

i am still thinking about the function

Re: Math Homework

chalo jee.. insan (da math teach is hea) :D

Re: Math Homework

how did you get that?

Re: Math Homework

i guess function will be y=5/4x

coz if leng is =y, 20

and wid = x , 16 20/16 give slope =5/4

not sure i don’t remeber this math anymore :smack2:

Re: Math Homework

Sounds good to me now on to the second prob.

Lots of cookies, cakes and dua's for you guys.

Re: Math Homework

well i know that i have space of 320 feet

so i just take two number which i multiply and give 320 or close to it .

coz are of rectangular is = l*w

so i choose two number which gave me 16 * 20 = 320


max is obvious coz all the space i have alredy filled up so there is no more space :) so again max will be 320 :) 

still i a, not sure coz i did this long time ago and my mind is not working right now coz iam doing my hw :smiley:

Re: Math Homework

so i was right, to some extent :D

Re: Math Homework

thanks for duas and cookies now what is ur second problem :halo:

Re: Math Homework

i guess

only thing is still itching me is assytope

coz if assy. is x=2 and y=0 then there is something should be there which i ma missing coz ic an’t think anything right now

Re: Math Homework

write an equation that defines a rational function with a vertical asymptote as x=2 and a horizontal asymptote at y=0

How did you find the slope insane uncle?

Shoaib...no cookies for you.

Re: Math Homework

check it out on ur graphing calculator yo :D

Re: Math Homework

it won’t make any different coz i now how the graphs look of tthis function and thats why i have dobts :smiley:

Re: Math Homework

Now we’re having doubts…guys guys what happend? :hehe:

Re: Math Homework

ia m uncle for god sake i am younger than belle baji

well if y = 20 and x = 16 the y/x give u slope

ok
so
we know when x = 2 then y = 0

                        we know when x = 16 then y = 20

what is difference in x and y

x went from 2 to 16 so change is = 14

y went from 0 to 20 so the change is =20

y/x give u a slope so 20/14=1.43

Re: Math Homework

i think is correct coz i am trying to rechecking different ways and ia m getting it but still can excatly remember but is much better u have nothing on the paper at least u try
