Step-by-step explanation:
5 days temperature = 100
So the temperature have to add to 500
6 days temperature = 90
500 + ? = 540
?=40
Answer:
Step-by-step explanation:
Rate of leakage, R(t) = 1400 e^0.06t gallons/h
fraction remains , S(t) = e^(-0.32t)
initial contaminant = 1000 gallon
gallons contaminant present after t hour is S(t) R(t)
G(t) = S(t) R(t)
![G(t) = 1400 e^{0.06t}\times e^{-0.32t}](https://tex.z-dn.net/?f=G%28t%29%20%3D%201400%20e%5E%7B0.06t%7D%5Ctimes%20e%5E%7B-0.32t%7D)
![G(t) = 1400 e^{- 0.26t}](https://tex.z-dn.net/?f=G%28t%29%20%3D%201400%20e%5E%7B-%200.26t%7D)
Put t = 18 hours
![G(t) = 1400 e^{- 0.26\times 18}](https://tex.z-dn.net/?f=G%28t%29%20%3D%201400%20e%5E%7B-%200.26%5Ctimes%2018%7D)
Taking log on both the sides
ln G = ln 1400 - 0.26 x 18
ln G = 7.244 - 4.68
ln G = 2.564
G = 13 gallons
