Acity's population was 30,200 people in the year 2010 and is growing by 950 people a year. give a formula for the city's population, p, as a function of the number of years, t, since 2010.

the formula should look like this:

 p=30200+950t

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
