Air contained within a piston-cylinder assembly undergoes three processes in series: a) process 1-2: compression at constant pressure from p1=10lbf/in2, v1=4ft3 to state 2. b) process 2-3: consant volume heating to state 3, where p3=50lbf/in2. c) process 3-1: expansion to the initial state, during which the pressure-volume relationship is pv=constant. sketch the process in series on p-v coordinates. evaluate the (a) volume at state 2, in ft3, (b) work for each process, in btu

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

Lorenzo ate 2/5 of his bag of almonds. his 4 friends ate equal shares of the remaining bag of almonds?

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
