Answer 1

I need help knowing how to get the average speed equation from the information given.
I know: Average speed = dist traveled/time traveled.

Answer 2

Answer 4

yeah so that is what you have to compute for each one
you are going to need some technological assistance, like a calculator
first off, what do you get when x = 1? you are going to use that number for each one, so lets get that first

Answer 5

how do I find that out?

Answer 6

replace x by 1

Answer 7

you mean t?

Answer 8

x, t whatever

Answer 9

xD it equals 57.17

Answer 10

ok so now the first one will be \[\frac{58\times 2-.83\times 2^2-57.17}{2-1}\]

Answer 11

55.51 ?

Answer 12

lets use this

Answer 13

http://www.wolframalpha.com/input/?i=%2858*2-.83*2^2-57.17%29%2F%282-1%29

Answer 14

yeah you got it, but i wrote it in kind of a silly way in wolfram so now you can use that for all of them
replace the 2 by various different values for t

Answer 15

Yay! so the values of t are the second number in the interval things given?

Answer 16

[1,1.5]
[p, t]
like that?

Answer 17

here is the same thing, only i replaced all the "2" by "1.5"
http://www.wolframalpha.com/input/?i=%2858*1.5-.83*1.5^2-57.17%29%2F%281.5-1%29

Answer 18

http://www.wolframalpha.com/input/?i=%2858*1.5-.83*1.5%5E2-57.17%29%2F%281.5-1%29
like so?

Answer 19

lol yeah looks exactly like what i wrote

Answer 20

hahah perfect, ok. Sorry, I think we posted at the same time xD

Answer 21

now you can use it as a template for all the rest

Answer 22

yeah you got it right on the first try
aint technology wonderful?

Answer 23

Dude, no joke.
So for part b of the problem?

Answer 24

Nevermind, I got it :)
