Question

Am i right? Medal if im right! most likely i am!

Answer 1

A student needs to make a square cardboard piece. The cardboard should have a perimeter equal to at least 92 inches. The function f(s) relates the perimeter of a cardboard piece, in inches, to the length of its side in inches. Which of the following shows a reasonable domain for f(s)?

23 < s < 46

23 < s < 92***

s ≥ 92

s ≥ 23

Answer 2

@SolomonZelman

Answer 3

You said the f(s) and where is it?
is it this 23<s<46 ?

Answer 4

so that means it is A not B?

Answer 5

@SolomonZelman ???

Answer 6

I didn';t get th question, I am just asking where is the f(s) ?

Answer 7

they compared the side of it to the perimeter...so that means F(s) = 96?

Answer 8

it can be anything.

Answer 9

I think the domain for f(s) is all values of s greater than or equal to 92, s>=92, as this is a requirement of the problem.

Answer 10

it can be
2(x+y)≤96
so
(x+y)≤48
but it can be anything see?

Answer 11

I am using x +y as width plus length which is all times 2 and supposed to equal at least 98.

in other words, - "2 unknown variables in 1 equation"

Answer 12

Yeah, @phi can help you, I am sure, I'm not good at this staff.

Answer 13

***
The function f(s) relates the perimeter of a cardboard piece, in inches, to the length of its side in inches.
***

this is ambiguous to me. It might mean side= f(perimeter) or
perimeter= f( side)

If "s" is short for side, then it would be perimeter= f(side)
the domain would be all "legal"s sides... any side 23 or bigger.

But there is a chance they want it the other way round.

Answer 14

so its the last one?

Answer 15

That would be my guess.

Answer 16

k thx :D
