Answer:
W(x) = 3.4 L - (25/1000)(L/s)*x
Step-by-step explanation:
it a tip
W(x) = 3.4 L - (25/1000)(L/s)*x
The maximum of the jug is 4 L.
now, the jug is 85% filled, then the amount of water in the jug is:
(85%/100%)*4L = 0.85*4L = 3.4L
Now, we pour 25 mL each second, so we could write a linear equation as:
W(x) = 3.4L - (25ml/s)*x
where x is the number of seconds that passed since the beginning,
But we want to write this in Liters, we have that:
1L = 1000mL.
Then 1mL = (1/1000) L
then we can write 25 mL as:
25m L = 25*(1/1000) L = (25/1000) L
Then we can write the equation as
W(x) = 3.4 L - (25/1000)(L/s)*x
which is the amount of water remaining in the jug after x seconds.
, which when solved equals 50.24. That's the third answer on your list.
