I used the term 'water concentration' because they explained it in the lesson that way:
so should i change it to 'water potential' by saying "area of higher water potential to an area of lower water potential"???

I am journalizing an adjuting entry, so I dont include the original supplies amount (which is $865). I was given $865 as the original amount of supplies at hand, at the end of the month the supplies on hand was worth only $349. According to my lesson, I am supposed to find out how much...
Hello,
I was told that I could post questions related to Financial Accounting Fundamentals on the Pre-calculas Math section of Physics Forum. But everytime I post questions related to this topic, I don't get any replies or help. Am I posting in the wrong category??

Thanks for the detailed explanation!
Now my only problem is with part d) and e)
I decided to graph the formula's i created in part c), and this is how it turned out.
the redline represents the tortoise, while the blue line represents the hare.
Using this graph, I will make an attempt to...
ok so for part a), what I am understanding is that the tortoise series is supposed to be like this:
Sn = 20 + 20 + 20 + 20....
since you mentioned that the qts is not asking for the total distance, but the distance for each individual minute. Since the tortoise is travelling at a constant speed...

3. The Attempt at a Solution
a)
so for part c) i came up with two formula's for the tortoise series:
the first formula (for the toroise series) is Sn = 20n This formula makes sense and agrees with part a). for example, if the...
ok so,
tan^2(x) - 1
---------------
tan(x) + 1
= tan(x) tan(x) - 1
------------------ ( im pretty sure tan(x) crosses out at this part)
tan(x) + 1
= tan(x) - 1 / 1
= tan(x) - 1
is this process correct?
for the numerator:
sin^2(x) - cos^2(x) / cos^2 (x)
inorder to find the answer, I have to divide cos^2(x) by each term in the expression:
so sin^2(x) / cos^2(x) = tan^2(x) (since sin(x)/cos(x) = tan(x))
and -cos^2(x) /cos^2(x) = -1
so is the answer tan^2(x) - 1
???
ok so i came up with an answer, can someone tell me if im on the right track?
((sin^2(x) - cos^2(x)) /cos^2(x)
-------------------------------------
(sin(x) cos(x) + cos^2(x)) / cos^2(x)
= tan^2(x)
----------
tan(x) + 1
= tan(x) tan(x)
-------------
tan(x) + 1
= tan(x) + 1...
srry im very confused, what do you mean by cross multiply and why would I need to cross multiply tan(x) - 1 by the denominator of the right side?
Can you provide an example!
ok so for the right side,if I use the formula: a^2 - b^2 = (a-b)(a+b)
then it becomes:
(sin(x) - cos(x)) (sin(x) + cos(x))
-------------------------------------
sin(x) cos(x) + cos^2(x)
how do i solve this??
Thanks for the quick reply!
Ok so i understand that i am supposed to leave the left side the same, but what do i do with the right side. You mentioned dividing both numerator and denominator with cos^2(θ), how do i do that?
so is it:
sin^2(x) - cos^2(x) /cos^2(x)...
