Question
After diluting salt water, the concentration of salt in the water is given by the function 
, where x is the time in hours since the dilution .
a. What is the concentration of salt in the water after 4 hours?
The correct answer is: a) We have to find concentration of salt in water after 4 hours X= 4
We have given the function
F(x) = 0.5x/ x2- 1
where x is the time in hours since the dilution
a) We have to find concentration of salt in water after 4 hours
X= 4
F(4) = 0.5(4) / (4)(4) – 1
= 2/ 15
= 0.1333
where x is the time in hours since the dilution
a) We have to find concentration of salt in water after 4 hours
X= 4
F(4) = 0.5(4) / (4)(4) – 1
= 2/ 15
= 0.1333
