The following graph shows the aggregate demand curve ( AD1 ) for this economy before the change in government spending. On the following graph, use the green line (triangle symbol) to plot the new aggregate demand curve ( AD2 ) after the multiplier effect takes place. For simplicity, assume that there is no “crowding out.”

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
