3.) A local city has grown significantly over the past several years and city council is considering hiring more people to work at the service department. In 2000, the amount of service
department employees was 20 and in 2015 the amount was 25 employees. The city is
anticipating the same amount of growth over the next several years and wants to maintain the
growth of employees as well. Write an equation to model this situation which will help city
council make their decisions.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

Consider the function represented by the equation 1/2 j + 1/4 k equals 3 which shows the equation written in function notation with j as the independent variable
