i got this 1.5159=(4+r)^(44)
anonymous
  • anonymous
hold on lemme see...
anonymous
  • anonymous
i think its 3.8
anonymous
  • anonymous
can you show me what you did ?
anonymous
  • anonymous
i was guessing lmao i hate math!
anonymous
  • anonymous
sorry:/
anonymous
  • anonymous
wait i think i got it....wait
anonymous
  • anonymous
what you get?
anonymous
  • anonymous
anyone can show me how to solve this? 2976.45=1963.45(1+r/4)^4(11)
anonymous
  • anonymous
You have an equation of the form: a = b(x^n) That will equal: a/b = x^n -> ln(a/b) = ln(x^n) -> ln(a/b) = n times ln(x) [ln(a/b)] / n = ln (x) e^( [ln(a/b)] / n ) = e^[ln(x)] = x "x" is your expression in parentheses, the 1 + a quarter of the rate.
anonymous
  • anonymous
what is that?? the formula i wrote is correct
anonymous
  • anonymous
Yes, your formula is correct and it matches mine. I am just using a general symbol method. For you to do some work here, you only have to make the substitutions and solve.
anonymous
  • anonymous
i dont understand that can you please just show me how to solve that formula i did it several times and got a wrong answer PLEASEE i beg you im so tired
anonymous
  • anonymous
You can do this! 2976.45=1963.45(1+r/4)^4(11) a = 2976.45, b = 1963.45, n = 44 Just make those substitutions and follow my solution method. Just plug in and follow the steps. Just try it. If you are that tired, I can give you a little more, but we tutors can't just give answers, we are required to show students how to solve and and top of it the students are supposed to do the work. I'll help as much as I can, but I can't just give ans answer.
anonymous
  • anonymous
Start by dividing both sides by what "b" is. It will start to isolate that exponential expression on the right-hand side.
anonymous
  • anonymous
i didd this many timessss im telling youu i just want to see where i went wrong i end up with 1.5159=5+r
anonymous
  • anonymous
^44
anonymous
  • anonymous
1.5159=(1+r/4)^4*11
anonymous
  • anonymous
then- 1.5159=5+r^44 im not sure about 5 than what do i doo
anonymous
  • anonymous
Good so far, keep going.
anonymous
  • anonymous
Wait, hold on.
anonymous
  • anonymous
This is where you went wrong. And before I show you, I just quickly want to say that doing it this way, you will learn. If I just did the steps, no way is anyone going to learn. This is learning by mistakes. Don't be afraid of mistakes. Now, The (1 + r/4) has to stay in parentheses for quite a while. Always respect the parentheses. They take precedence over the exponentiation. If you don't like that long expression in parentheses, call it "x" for now.
anonymous
  • anonymous
So, I'll take over from here for a little while and give you a little break. Hold on while I type.
anonymous
  • anonymous
1.5159286 = (1 + r/4)^44 ln 1.5159286 = ln [(1 + r/4)^44] = 44 times ln [(1 + r/4)] (ln 1.5159286) / 44 = ln [(1 + r/4)] e^[(ln 1.5159286) / 44] = e^(ln [(1 + r/4)]) = (1 + r/4)
anonymous
  • anonymous
Are you still getting this or did you get lost anywhere along the way? Should I stop or go on?
anonymous
  • anonymous
i dont understand the way you type i have all the steps in my paper can you just give me the second to last line of this problem so i can see if its the same i get 1.0094=4+r
anonymous
  • anonymous
then i have to take away 4 from each side
anonymous
  • anonymous
i keep getting an negative number
anonymous
  • anonymous
ok, we'll do it that way. Hold on.
anonymous
  • anonymous
1.5159^1/44=4+r^1/44 this is where i can stuck putting it to the power of ^1/44 i get 1.0094 which idk is right or not please help me fast its late
anonymous
  • anonymous
e^[(ln 1.5159286) / 44] = e^(ln [(1 + r/4)]) = (1 + r/4) e^[(ln 1.5159286) / 44] - 1 = r/4 4(e^[(ln 1.5159286) / 44] - 1) = r The right side is the rate. The left side is: 0.03800011 That's 3.8%
anonymous
  • anonymous
That's the annual rate. It's 4 times the quarterly rate of: 0.9500028 percent.
anonymous
  • anonymous
so where did i go wrong
anonymous
  • anonymous
I know it's late and you're tired, so tomorrow, you might want to go over all of this. I strongly recommend this. Good working with you and thx for the recognition. More importantly, just hang in there! You went wrong by taking that 1 + r/4 out of the parentheses. That stays in there until the very end.
anonymous
  • anonymous
Fast? It's going to take me a while just to read it!
anonymous
  • anonymous
thats fine
anonymous
  • anonymous
Well, I got problem #11, it's "b", not "c" like you have it, but you were not far off.
anonymous
  • anonymous
thanks
anonymous
  • anonymous
#12 is quarterly, not monthly. I don't think you are getting this just yet. You need to practice this a lot more.
anonymous
  • anonymous
these are practice problem i did like 50 and these are the ones i wasnt sure about
anonymous
  • anonymous
i just want to know which ones i need to practice more
anonymous
  • anonymous
how are 13 and 14 last two?
anonymous
  • anonymous
im sure about the rest just not these 4
anonymous
  • anonymous
You had #11 and #12 wrong and I got you right answers. I figured out #13 (didn't look at #14 yet). I need to see your work since you are not getting these right. Show me your work on #13.
anonymous
  • anonymous
my work is on paper its going to take me a while to type but i think 13 is okay
anonymous
  • anonymous
Yes, #13 is definitely 88.
anonymous
  • anonymous
for 14 i think its wrong
anonymous
  • anonymous
What is "n" and "an"? I don't get what those expressions mean. To do this problem, I need to know what "n" and "an" stand for.
anonymous
  • anonymous
thats what im trying to figure out
anonymous
  • anonymous
Not the values, what is the meaning of "n" and "an"? They stand for something even before we figure out the values.
anonymous
  • anonymous
i think n is number of cells and an is days or vise versa thats what im trying to figure out
anonymous
  • anonymous
i'll just go with A
anonymous
  • anonymous
Hold, on I figured it out algebraically.
anonymous
  • anonymous
I'm just trying to relate my answer back to the crazy notation in the problem.
anonymous
  • anonymous
You're going to have to help with relating the answer back to the problem's notation, but here it is in how I look at it: For any day, starting with the 3rd day, that day's number of cells is: [2 x (# cells in previous day)] - (# cells in previous to previous day) + 3 "previous day" is "day - 1" "previous to previous day" is "day - 2" Making sense?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
I checked this answer out up to 88, which is day 7. Can you get this back into that crazy notation?
anonymous
  • anonymous
not really other than -1
anonymous
  • anonymous
Well, I know my formula works like a charm. We could try together to get that into the notation from the problem, but I still don't know about that "an" and "n". Are you sure that that problem was written down right?
anonymous
  • anonymous
While you're answering that, I'm working on that notation.
anonymous
  • anonymous
its A for sure thanks for your help
anonymous
  • anonymous
Yes, I just confirmed A. I figured out the notation, but you might want a bit of explanation on it.
anonymous
  • anonymous
I don't know where that post of yours went, I don't see it anymore, but A was correct, for sure.
anonymous
  • anonymous
Well! It looks like we're done! Nice working with you and good luck in everything!
anonymous
  • anonymous
Your so nice thank you so much please keep in touch please
anonymous
  • anonymous
And you're nice, too! You made my day! :-)
anonymous
  • anonymous
btw, "an - 1" is the # of cells in the previous day, but I think you know that by now.
anonymous
  • anonymous
And this was exhausting!
