Answer:

Step-by-step explanation:

Assuming the decay factor, m = 0.0005

f(x) = $1 - e^{-mx}$

f(9000) = $1 - e^{-0.0005*9000}$ = 1 - 0.0111 = 0.99

Answer:

165 liters of 15% solution

Step-by-step explanation:

15F + 65S = 60(1650)

F + S = 1650

F = 1650-S

15(1650-S) +65S = 99000

50S = 99000-24750= 74250

S = 74250/50 = 7425/5 = 1485 liters of 65% solution

F = 1650-1485 = 165 liters of 15% solution

65 is much closer to 60 than 15 is, so you know there will be mostly 65% solution with relatively little 15%

Hope this helps, have a nice day/night! :D
