Which graph represents the function y = cos(4x)?<br><br> Answer is graph B
VARVARA [1.3K]

Answer:

Step-by-step explanation:

Let the equation of the cosine function is,

y = Acos(Bx)

From the graph attached,

A = Amplitude = \frac{1-(-1)}{2}

   = 1

B = \frac{2\pi}{\text{Period}}

B = \frac{2\pi}{\frac{\pi}{2}-0}

B = \frac{4\pi}{\pi}

B = 4

Therefore, equation of the cosine wave given in the graph will be,

y = 1.Cos(4x)

y = Cos(4x)

Look at the table showing prices of different items at a store.
kati45 [8]

The types of items that cost less than $3.75 per item are Paperbacks and notebooks.

<h3>How do we determine the price of a unit item in a word problem?</h3>

The price of a unit item can be determined by dividing the total price by the number of units sold.

Given that:

Paperbacks sold 3 units for $10.65;

  • 1 unit will be sold for = $10.65/3 = $3.55

Notebooks sold 4 units for $14.36;

  • 1 unit will be sold for = $14.36/4 = $3.59

Puzzles sold 3 units for $11.85;

  • 1 unit will be sold for = $11.85/3 = $3.95

Picture frame sold 4 units for $15.20;

  • 1 unit will be sold for = $15.20/4 = $3.80

Therefore, from the above calculations, we can conclude that the types of items that cost less than $3.75 per item are Paperbacks and notebooks.
