Answer:

Options B and D

Step-by-step explanation:

Phrase shift of a trignometric function is the horizontal shift of the function towards right or left.

Vertical shift is shift up or down.

The graph of y = sin x is translated three units down.

-- This is vertical shift and not phase shift.

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

-- This is a phase shift as y = csc (x+3)

The graph of y = cos x is translated three units up.  -- No, vertical shift.

The graph of y = sec x is translated three units to the left. -- Yes, phase shift

The graph of y = cot x is reflected over the horizontal axis. -- No, reflection

The graph of y = tan x is reflected over the vertical axis.-- No, reflection

Only options B D are phase shifts.

Carly wants to add texting to her cell phone plan. She has two choices in texting packages. The TURKEY plan charges $.15 per tex
Usimov [2.4K]

Let x be the number of texts (amount of texts) Carly does in a month.

Let y be the "total" amount Carly will have to pay in a month.

Then, as per the TURKEY plan, Carly's monthly total cost will be represented by the equation as shown: y=0.15x+20

As we can clearly see in the above equation even if Carly does not text a single message (when x=0), even then they will have to pay $20 for that month.

For the GOBBLE plan, the equation will be: y=0.2x.

In this plan as there is no fixed charge, Carly wont have to pay anything extra if they dont make a call.

PLEASE HELP ASAP, THANK YOU

First step is to plot all the given coordinates in the xy plane.

Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.

Formula to find the area of trapezium is:

Area = \frac{(AD+BC)}{2} *DE

= \frac{4+6}{2} *5

=\frac{10}{2} *5

= 5 * 5

= 25 square units.

So, third choice is correct.

Hope this helps you!
