What is the amplitude, period, and phase shift of f(x) = −5 sin(x + 2π) − 4? 1. Amplitude = −5; period = π; phase shift: x = 2π 2. Amplitude = 5; period = 2π; phase shift: x = 2π 3. Amplitude = −5; period = π; phase shift: x = −2π 4. Amplitude = 5; period = 2π; phase shift: x = −2π

Amplitude = 5; period = 2π; phase shift: x = −2π

Just took the quiz and got 100%

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.
