Step-by-step explanation:
The point of the dashed line y=x in the problem statement graph is that the inverse function is a reflection of the function across that line. (y and x are interchanged) The graph of selection C has the appropriate pair of curves.
The next larger ten thousand is 70,000 .
The next smaller ten thousand is 60,000 .
67,000 is closer to 70,000 than it is to 60,000 .
So 70,000 is the nearest ten thousand.
8 times 18 is 144. then take that and divide it by 60 seconds which equals a minute. your answer is 2 minutes and 40 seconds
Answer:

Step-by-step explanation:
The given initial value problem is;

Let

Differentiating both sides of equation (1) with respect to
, we obtain:

Differentiating both sides of equation (2) with respect to
gives:

From equation (1),

Putting t=0 into equation (2) yields

Also putting t=0 into equation (3)

The system of first order equations is:

540ml with 12% solution
get 12% of 540
540 times 0.12 = 64.8 ml of pure acid
