1. Graph the function f(x)=4cos(x). (Be sure to label your x-axis.)

Mekhanik [1.2K]

ANSWER

To graph the function

$y=4cos(x)$ we need to plot some few points within one period. Since the interval is not given, we shall use $[0,2 \pi]$ '

$\left \begin{array}{cc}x&y=4cos(x)\\0 &4\\\frac{\pi}{2}&0 \\ \pi&-4\\\frac{3\pi}{2} &0\\2\pi&4\end{array}\right$ .

We plot the above points to obtain the graph as shown in the attachment.

Last Sunday a certain store sold copies of Newspaper A for $1 and Newspaper B for 1.25. If r percent of the stores revenue came

Oksanka [162]

Answer:

Option 400p/500-p

Step-by-step explanation:

Let the number of newspaper A sold be 'x'

and the number of newspaper A sold be 'y'

Therefore,

Total revenue = $1x + $1.25y

Total newspapers sold = x + y

Therefore,

according to the question

r = $\frac{x}{x + 1.25y}\times100$ ..........(1)

and,

p = $\frac{x}{x + y}\times100$

(x + y)p = 100x

y = $\frac{x}{p}\times100-x$

y = $\frac{x(100-p)}{p}$

substituting y in 1

r = $\frac{x}{x + 1.25(\frac{x(100-p)}{p})}\times100$

r = $\frac{100p}{p+125-1.25p}$

r = $\frac{100p}{125-0.25p}$

multiply and divide the RHS with 4

we get

r = (400p)÷(500-p)

hence,

Option 400p/500-p

It is Arithmetic. It follows a pattern of divide by 2, which gives it the name "Arithmetic" and you can think of it as "Arithmic," which sounds like rythm. It follows the rythm of Divide by 2. Hope this helps, and let me know if I made any mistakes!
