A Wall Street Journal story in October 2008 reported that inmates in federal prisons could use packaged mackerel fillets (called macks) to obtain goods and services, such as haircuts (the barber charged two macks). Some prisons provide lockers in which inmates can store their macks. Macks could be considered a form of money in prison because macks serve as a: Macks serve all the functions listed. unit of account. medium of exchange. store of value.

Solve the right triangle. B = ?°?' (Round to the nearest integer as needed.) a = ? m (Round to the nearest integer as needed.) b = ? m (Round to the nearest integer as needed.)
Select the correct transfer function \frac{X_2(s)}{F(s)} of the following system. Both masses slide on a frictionless surface and k = 1N/m \frac{X_2(s)}{F(s)} = \frac{1}{s^4 + 2s^2} \frac{X_2(s)}{F(s)} = \frac{5}{s^4 + 2s^3 + 1} \frac{X_2(s)}{F(s)} = \frac{s+1}{s^3 + s^2 + 2} \frac{X_2(s)}{F(s)} = \frac{s}{s^4 + 2s^2} \frac{X_2(s)}{F(s)} = \frac{1}{s^2 + 2s + 2}
