A cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 11, the vertical shif

omeli [17]

We have been given that a cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 11, the vertical shift is 9 units down, and the period of the function is $\frac{7\pi}{12}$ . The graph of the function does not show a phase shift. We are asked to write the equation of our function.

We know that general form a cosine function is $y=A\cos(b(x-c))-d$ , where,

A = Amplitude,

$\frac{2\pi}{b}$ = Period,

c = Horizontal shift,

d = Vertical shift.

The equation of parent cosine function is $y=\cos(x)$ . Since function is reflected about x-axis, so our function will be $y=-\cos(x)$ .

Let us find the value of b.

$\frac{2\pi}{b}=\frac{7\pi}{12}$

$7\pi\cdot b=24\pi$

$\frac{7\pi\cdot b}{7\pi}=\frac{24\pi}{7\pi}$

$b=\frac{24}{7}$

Upon substituting our given values in general cosine function, we will get:

$f(x)=-11\cos(\frac{24}{7}x)-9$

Therefore, our required function would be $f(x)=-11\cos(\frac{24}{7}x)-9$ .

There are 44 total small egg cartons, 264 / 6 = 44

There are 176 total medium egg cartons, (264 / 3) x 2 = 176

There are 44 total big egg cartons, 176 + 44 = 220

264 - 220 = 44

<u>Note: (So you don't get confused) Above is just the number of egg cartons, below is the number of eggs.</u>

There is a total of 352 eggs in the small egg cartons, 44 x 8 = 352

There is a total of 2112 eggs in the medium egg cartons, 176 x 12 = 2112

There is a total of 792 eggs in the large egg cartons, 44 x 18 = 792

Hope this Helps! :)
