-sin48°
sin48°
-sin132°

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

da freeck kinda math is this just drop out

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

10 b/c 5*2 =10

step-by-step explanation:
