The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. A cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a volume of 120 liters. Find the pressure if the volume is decreased to 105 liters and the temperature is increased to 350 degrees K.

What is the difference between a permutation and a combination? Use an example to explain.

The parent function 𝑦 = 𝑓(𝑥) passes through the points (0, 1), (1, 2), (2, 3). After applying a transformation the new graph passes through the points (-3, 3), (-2, 4), (-1, 5). What is the general equation that represents the graph of the new coordinates?
