Two agricultural sciences majors have been collecting data on tomatillo plants. Their data shows that when they puts 20 tomatillo plants in an acre plot, each plant yields 9 kilograms of fruit. For each additional plant (up to 65 ), the yield of each plant decreases by 0.1 kilograms.
Write a function f(x) that gives the TOTAL yield of the garden in kilograms of tomatillos, where x is the number of tomatillo plants.
How many tomatillo plants should these students put in an acre plot to maximize the total yield?
What is the maximum mass of tomatillos they can grow in an acre?

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.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
