x≥5

Step-by-step explanation:

The function f(x)=2*sqrt(x-5) is transformed from the parent function f(x)=sqrt(x) by:

vertically stretched by a factor of 2

right 5 units

a parent rational equation has a domain of [0,+∞)

this certain equation is moved 5 units to the right, so the domain is:

[0+5,+∞)⇒[5,+∞)

So the domain of f(x)=2*sqrt(x-5) is [5,+∞)

which as an inequality is x≥5

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.

answer: it's a
