Suppose two tasks, a and b, must use the shared variable buf_size. task a adds 2 to buf_size, and task b subtracts 1 from it. assume that such arithmetic operations are done by the three-step process of fetching the current value, performing the arithmetic, and putting the new value back. in the absence of competition synchronization, what sequences of events are possible and what values result from these operations?

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

yes

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
