Which of the following statements best describes a trigonometric function having undergone a phase shift? select all that apply.

the graph of y = sin x is translated three units down.
the graph of y = csc x is translated three units to the right.
the graph of y = cos x is translated three units up.
the graph of y = sec x is translated three units to the left.
the graph of y = cot x is reflected over the horizontal axis.
the graph of y = tan x is reflected over the vertical axis.

The graph of y = csc x is translated three units to the right.

AND

The graph of y = sec x is translated three units to the left.

Step-by-step explanation:

A phase shift means that the function is shifted horizontally, either left or right.

Thus, only the options with left or right are horizontal phase shifts.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
