Suppose a company needs temporary passwords for the trial of a new time management software. Each password will have one digit, followed by one letter, followed by two digits. The digit 7 will not be used. So, there are 26 letters and 9 digits that will be used. Assume that the digits can be repeated. How many passwords can be created using this format?

A container is in the shape of a hollow inverted right circular cone of height 60 cm and radius 12 cm . The container, which is initially empty, is placed, with its axis vertical, under a tap where water is flowing in at the constant rate of kcm3/s. The rate at which the height of the water in the container is rising 12 minutes after it was placed under the tap is 601cm3/s. Calculate the value of k.

A tank of water is connected to a tank of compressed air that produces a gauge pressure Pgauge =2.5×104Pa above the water. A small hole is opened in the side of the tank at a depth d=2.0m below the surface of the water and H=3.0m above the ground. Water leaves the hole moving parallel to the ground. What is the distance R that the water travels from the tank? You may assume atmospheric pressure outside the tank and that the diameter of the hole is very small compared to the diameter of the tank.
