Answer:

It has amplitude of \frac{1}{4}.

It is a horizontal shift of the parent function \frac{\pi}{3} units left.

Step-by-step explanation:

We have the function, f(x)=\frac{1}{4}\cos (x+\frac{\pi}{3})-1.

It is clear that the parent function is g(x)=\cos x.

So, we see that,

The amplitude of the function f(x) is \frac{1}{4}, which gives, \cos x => \frac{1}{4}\cos x.

Also, g(x) is translated \frac{\pi}{3} units to the left, which gives, \frac{1}{4}\cos x => \frac{1}{4}\cos (x+\frac{\pi}{3}).

Further, the function is translated 1 unit downward, resulting in f(x)=\frac{1}{4}\cos (x+\frac{\pi}{3})-1.

So, the correct options are,

It has amplitude of \frac{1}{4}.

It is a horizontal shift of the parent function \frac{\pi}{3} units left.

Answer:

Hey! I think I can help.

Parallel lines are lines that can't meet.Perpendicular lines are lines that can meet.

e.)Since the line at 12 and the line at 9 meets then it is a perpendicular line.

c.)Perpendicular line.

a.)Perpendicular line.

b.)Parallel line.

d.)Depending on how they are faced if the ends of the telephone wire meets the second one then it is perpendicular but if not then it is parallel that's if they are in different directions which they can not meet.Thank you for the question
