Water contained in a piston–cylinder assembly, initially saturated vapor at 120° C, undergoes an isothermal process during which its volume (a) doubles, (b) reduces by half. For each case, fix the final state by giving the quality or pressure, in MPa, as appropriate. Locate the initial and final states on sketches of the p–υ and T– υ diagrams

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
