A(t) = Ao*e^(-rt)
-rt = ln [ A(t)/ Ao]
t = - ln [ A(t)/ Ao] / r
r= 0.0124% = 0.0124/100 = 0.000124
A(t)/A0 = 10% = 10/100 = 0.1
Now substitute
t = - ln [0.1] / 0.000124 = 2.3025851 / 0.000124 = 18,569 years
Your result will depend on how you round ln(0.1).
Alright! Let me draw one out for you! c: Here you go! I hope this helps! It took me a while ~w~
Don't juge my handwriting It took a while T~T I couldn't put in the whole picture but the pattern was.
Turkey - Japan : 1.7
UK - Finland: 2.8
Austria - Germany : 3.3
Spain - Sweden : 4.4
Denmark- Switzerland : 5
France - Norway : 5.5
Canada - U.S : 7.5
Hope this helps!~
Inverse function: you need to exchange the position of x and y, in other words,
x = (5-2y^2)/(3y+10) , then, if you need a representation of y with respect to x, then you need to perform some math.
Answer: $7
Step-by-step explanation: if a stapler cost $3, then 20staplers will cost $60
Amount left will be $200-60=$140
Cost of one organiser will be $140/20
That will be $7
