Ответ:
41.04
Step-by-step explanation:
t represents time in hours, and we want to find the concentration after 10 hours. Therefore, we can substitute 10 in for t and solve.
s(t)=![500*e^{-0.25t}](/tpl/images/0635/5579/66d44.png)
s(10)=![500*e^{-0.25(10)}](/tpl/images/0635/5579/ee3f1.png)
Multiply the numbers in the exponent
s(10)=![500*e^{-2.5}](/tpl/images/0635/5579/424b9.png)
Evaluate the exponent
s(10)=500*0.08208499862
Multiply
s(10)=41.0424993119
Rounded to the nearest hundreth:
s(10)=41.04
So, after 10 hours, the concentration of salt will be 41.04
