Each time you visit the state fair, you play some games at the Midway. One game has four prizes (A, B, C, D). (a) How many different four letter sequences are possible if each letter is chosen from {A, B, C, D} with repeats allowed? (b) How many different four letter sequences have each letter occurring exactly once? (c) How many different four letter sequences don't contain B? (d) How many different four letter sequences have two letters, each of which occurs twice?

A battery powered torch uses a 9 V battery and dissipates 0.25 W of electrical power in the bulb.
If the torch is used for 1.0 hours then how much charge has passed through the bulb?
Predict whether the entropy change of the system in each of the following is positive or negative.1. O2(g) → 2O(g)2. N2 (g, 10 atm) → N2 (g, 1atm)3. 6CO2(g) + 6H2O(g) → C6H12O6(g) + 6O2(g)4. 2 H2 (g) + O2 (g) → 2 H2O (l)5. NH4Cl (s) → NH3(g) + HCl (g)
) Solve the area bounded by the curve y = 4x-x² and the lines x = -2 and y = 4.
Find the area, take the elements of the area parallel to the x-axis. y= 2x³-3x³-9x; y=x²-2x²-3x.
