Question Imagine there are 3 periods, t=0,1,2 (with t=0 being today). A bond pays $100 in period 1 and $120 in period 2. The interest rate from period 0 to 1 is 10% and the interest rate from period 1 to period 2 is 5%. 1. What is the value of the bond in period 0 dollars (present value)? 2. What is the value of the bond in period 2 dollars (a future value)? 3.

Suppose that in a closed economy GDP is $10.8 trillion, consumption is $5.6 trillion, taxes are $4.1 trillion, transfers are $1, and the government runs a budget surplus of $2 trillion. What is the value of public savings based on this information? Provide your answer in trillions and round it to two digits after the decimal. Ex. If your solution is 6.3

Drop down choices for both a. and b. -cost-push inflation -a change in inflation expectations -demand-pull inflation The Phillips Curve and Inflation - End of Chapter Problem For each scenario, determine whether inflation expectations, demand-pull inflation, or cost-push inflation will change. a. A rapid influx of foreign investment causes the output gap to become more positive. This gives rise to b. The president unexpectedly announces a tariff on aluminum and steel. This causes

CIRCLE ALL ANSWERS AND PROVIDE UNITS 1. (20 points) Mohr's Circle and Stress Elements Oy An element in plane stress (shown above) is subjected to stresses Ox - 70 MPa, Oy, and Txy - 50 MPa. Using the Mohr's Circle equations, determine the following: a principal stresses, b. the maximum shear stress, C. the principal angle, d. If one of the principal stresses is negative, what does a negative stress mean? **Using just proper equations is acceptable, but Extra Credit will be given if Mohr's Circle is drawn out.

You make a swimming pool 3.92 M in magnesium acetate, Mg(CH3COO)2 hoping to keep it from freezing during the winter. Its density is 1.23 g/ml. What will its normal freezing point be? Give your final answer (remember, you're looking for the new normal freezing point) to 1 decimal place (just to keep CuLearn happy) Put C for your unit (I don't know how to find the degree sign for answers...) Kf(H2O) = 1.86 °C/m
