Ok all solved, feel free to pm me if you are still interested and still need the answer. I can also give you an explanation for each answer so you can reproduce the answer on your own
hello I can solve this for you, give me a few min to get home and will send a reply in the following mins
As a side note : I know that sometimes you have some restrains and you want to have a good mark on some subjects for a reason or another, but this should be exceptional

You want to cheat on the test?
Just go on khanacademy.org for a couple hours.
Just go on khanacademy.org for a couple hours.
I have been doing precalculus this whole quarter and doing pretty well. 80-90% on the 3 last tests. Now we have a 4th one which involves the 8 logarithmic properties and Exponential Functions, Graphs of exponential functions, Logarithmic functions, Logarithmic properties, Graphs of Logarithmic functions, Exponential and logarithmic models
I have been really trying to understand them but I just do not get log, ln and word problems such as half-life of a substance decay. I have spent countless hours trying to learn the formulas and where all the numbers go (especially on word problems) but just can't seem to get it. With 8 hours left and lack of sleep, I don't know how I am going to do this. I am tired because I stayed up really late last night studying the same stuff. I really need to go to bed but I can't, I need to at least figure I way out of it.
So here is the deal. I am offering a .07btc reward (upon getting home, and checking the answers/work in the pictures you sent me and having your answers/work be atleast 70% correct.)
I will offer .3 more if they are 90% correct.
Here is how it will work, You will give me your number, preferably an iphone. I will text you right now to confirm that images work, maybe I can email them to you (mail app) so you can print them out and write on the paper, then send it back via phone picture. Once the test comes in 8 hours (5:30pm gmt), I will take a picture of at least 2 pages, there are 4 but I want to give you time to figure the correct answers out, I can try the other half, cause it's mainly word problems I have always had problems with. In the 50 min time range, or even 40 since I need them before class ends (it runs from 5:30gmt - 6:20gmt) you will complete the problems in pen (with super easy to read handwriting) and send them to me though the phone, which then I will copy them onto my paper.
I know this is cheating, wrong, "just learn the math idiot", but I am really not stupid, something in me just can't put different variables such as time, half-life, decay rate.. etc into a formula. I am studying art and this is the only math credit I have left, I won't be needing calculus or anymore classes related to math after this. I currently have a 75% in the class due to low quiz scores, literally get them the next day after we had the lecture on that chapter/section. The teacher is really bad too, he goes too fast and gets irritated when people ask him questions. He has a 1.5/5 stars on rate my teacher so it's not only me, I just had no choice for another math class. If I fail this test I will fail the class. Plain and simple. I have the finals but the finals will be more spread out with easier precalc stuff I actually learned and able to do.
message me on here and I will get back to you asap. Just please, don't try to help me if you don't know precalculus or don't know these sections. It all depends on you with a nice little prize in the end.
Most of the questions will be using these formulas.
and the questions will be like these
1. If $6,000 is invested in a bank account at an interest rate of 3% per year, find the amount in the bank
after 5 years if interest is compounded monthly. (Use an equation and show work.)
2. A scientist begins with 20 grams of a radioactive substance. After 7 days, the sample has decayed to
17 grams. Find the half-life of this substance. (Use an equation and show work.)
3. A wooden artifact from an ancient tomb contains 25 percent of the carbon-14 that is present in living
trees. How long ago, to the nearest year, was the artifact made? (The half-life of carbon-14 is 5730 years.)
4. The count in a bacteria culture was 600 after 15 minutes and 1000 after 40 minutes. Assuming the
count grows exponentially, find the formula for the number of bacteria after t minutes (hint: need to find
the initial size of the culture).
5. A turkey is pulled from the oven when the internal temperature is 165° Fahrenheit, and is allowed to
cool in a 75° room. If the temperature of the turkey is 145° after half an hour, how long will it take the
turkey to cool to 110°? (Show work and use appropriate equations.)
If you can answer all of these and possibly a couple more within 40 minutes, with work, Please contact me.
Really need somebodies help. Thank you so much in advance, hopefully I can pass this dang test and move on to doing what I love...
