Q2.
Just a thought. If the drum is 64 gallons, and the rate of flow into the drum is 2 gallons per hour. It would take 32 hours just to fill it if it had no leaks. Did you make a typo? Q3. The absolute value of a positive number (or zero) is itself. The absolute value of a negative number is the conjugate (positive). This means both A and B are the largest values. I suspect your source for questions is not great... |
