Darya [45]

<h2>Answer:</h2>

yes

<h3>Step-by-step explanation:</h3>

This is a piecewise-defined function because it is defined by two or more equations over a specified domain is. The graph of this function is shown below.

For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. Which equation can be used to find the maxim

ziro4ka [17]

To determine the maximum and minimum temperatures at which nitrogen remains a liquid, use the equation |x - (-333.32)| = 12.78, where x is equal to the maximum and minimum temperatures. Using this equation, the maximum temperature is -320.54 degrees Fahrenheit while the minimum is -346.10 degrees Fahrenheit.
