Answer 1

can some help me?

Answer 2

Don't ask for help on other peoples questions. I can not help you.

Answer 3

well this is like building a distance time graph
you have to know what is the independent variable and the dependent variable

Answer 4

Don't you have to write a function rule...?

Answer 5

yup but before you write a function rule you must picture out a graph (which IS itself a function) and for that you have to know what is dependent and what is independent

Answer 6

in this question you can forget about the rate and the person's weight

Answer 7

the time and the calories burned?

Answer 8

exactly
so according to your common
who is depending on who? the calories are depending on the time or the other way around?

Answer 9

*common sense

Answer 10

if the guy doesn't spend time exercising he's not gonna lose calories, now is he?

Answer 11

Nope

Answer 12

So the calories depend on the time

Answer 13

@nopen

Answer 14

Oh sorry my OS is lagging again =_=

Answer 15

Yup

Now if you're familiar

Y is always the dependent variable and x is independent variable

Answer 16

So since they said its 420 calories per hour

Then it should be 420 * t
For any given hour

Answer 17

Where t is time

Answer 18

So

y = 420*t

Answer 19

That is our range

And our domain is t

Answer 20

So far so good?

Answer 21

@samsteronbroadway ?

Answer 22

SO SORRY IT WAS LAGGING I COULDN'T READ IT @nopen

Answer 23

Yes is that it?

Answer 24

yup C(t) = 420*t

Answer 25

wait so c(t)= 420t? or y=420t? @nopen Thanks so much!

Answer 26

yes it's c(t) = 420t

Answer 27

lol I wasn't sure so I deleted my answer hahaha
nice @nopen
