A technique for measuring cardiac output depends on the concentration of a certain dye after a known amount is injected into a vein near the heart. In a normal heart, the concentration of the dye at time x (in seconds) is given by the function defined by $$g(x) = -0.007x^4 + 0.142x^3 - 0.053x^2 + 1.73x$$ Find g(0). Write the answer in box #1. Find g(4). Write the answer in box #2. Round your answer to 3 decimals. Blank # 1 Blank #2

5. Consider a well-insulated horizontal rigid cylinder that is divided into two compartments by a piston that is free to move but does not allow either gas to leak into the other side. Initially, one side of the piston contains 0.9 m³ of hydrogen ($H_2$) gas at 530 kPa and 80°C while the other side contains 0.9 m³ of methane ($CH_4$) gas at 530 kPa and 25°C. Now thermal equilibrium is established in the cylinder as a result of heat transfer through the piston. Using constant specific heats at room temperature, determine the final equilibrium temperature in the cylinder.
