Answer:
The solution is
Step-by-step explanation:
From the question we are told that
The function is
Generally the above equation can be represented as
=>
From the question we are told that at y(0) = 1
So
Let x be the amount of pure water (in mL) you need to add. The new mixture would have a total volume of 80+x mL. The solution you have contributes 0.95 mL of alcohol for each mL of solution, so that it currently contains 0.95*80 = 76 mL of alcohol. You want to the new mixture to have a concentration of 10%, so that
76 / (80 + x) = 0.1
==> 76 = 0.1(80 + x) = 8 + 0.1x
==> 68 = 0.1x
==> x = 680 mL
It's the first one. Note that for each unit increase in x, y increases by 1/2:
outputs are 1/2, 2/2, 3/2, 4/2, corresponding to 1, 2, 3 and 4 as inputs.
