Assume that the price per unit d of a certain item to the consumer is given by the equation d=35-10x where x is the number of units in demand. The price per unit from the supplier is given by the equation s=2x+20 where x is the number of units supplied. Find the equilibrium price and the equilibrium quantity.

The average salary of the employees in a certain organization is equal to 9300 with a standard deviation of 1400. It was decided to reduce 10% of each employee's salary and it was also decided to reduce another 100. What are the new average and standard deviation?

a student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vO= 12.5 m/s. the cliff is h=38.0 m above a flat, horizontal beach as shown in the figure. (c) write the equations for the c- and y-components of the velocity of the stone with time. (use the following as necessary: t. let the variable t be measured in seconds. do not include units in your answer.) (d) write the equations for the position of the stone with time, using the coordinates in the figure. (use the following as necessary:t. let the variable t be measured in seconds. do not state units in your answer.)

An electron is ejected with speed v=107 m/s into the uniform field created by the flat and parallel sheets of the figure. The field is directed vertically downwards and is null except in the space between the sheets. The electron It enters through a point located at an equal distance between the two sheets. Yes when you leave field, the electron passes just through the edge of the sheet: a) Find the intensity of the field b) Find the direction of the speed of the electron when it leaves the field.
