Use this information to determine your economy’s original AEP, AP, and IS curve.

C=500-10r+0.9YD

Ip=250-40r

G=390

T=100+0.1Y

X=600

M=400+0.06Y

  1. Use the four graphs we developed in class to determine the IS curve for this economy with r=0 and r=5. Show how the following change would affect this economy. You need to determine what has changed in the economy, what parts of the economy it affects, and how it changes the IS curve. Be sure to address any shifts as well as changes in slopes that may occur. You must show these changes mathematically, graphically, and then describe these changes verbally.
    1. M = 400+0.01Y
  2. Now, what happens to the economy when this change occurs? Return to your original equations. Suppose Consumers decide that credit is a good way to finance their expenditures on durables, so they become more interest sensitive, C=500-50r. Determine what has changed in the economy, what parts of the economy it affects, and how it changes the IS curve. Be sure to address any shifts as well as changes in slopes that may occur. Show these changes mathematically and graphically.

this is a two part answer please help :)

You pour 100 g of cold milk (T_m=5 degrees C) into your 500 g hot coffee (T_c=80 degrees C) and mix them together. Assume this is an isolated system in which no heat is lost to the cup or surrounding air. Specific heat of milk: c_m= 3.97 J/(g°C), specific heat of coffee: c_c= 4.184 J/(gºC) a. What is the final temperature of your drink after the milk and coffee are in thermal equilibrium? b. What happened to the temperature of...

1. For the next two questions use the following information to determine your answers. A random sample of 230 workers at a company were surveyed about their satisfaction with their life. The answer about their satisfaction (not, somewhat, very) was recorded along with their annual wages (1 = $20K - $35K, 2 = $35K - $50K, 3 = $50K - $75K, 4 = $75K - $90K). Below is the gathered data. Assuming there’s no relationship between income and life satisfaction,...
