What is the phase shift of y = sin(1/2 x - pi/2)?

π

Step-by-step explanation:

The standard form of the sine function is

y = a sin(bx + c)

where a is the amplitude, period = and

phase shift = -

here b = , c = -

phase shift = -

= × 2 = π

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
