3 0

Answer:

x = 2* pi* n

Step-by-step explanation:

cos(2x) cos(x) + sin(2x) sin x =1

We know cos(s) cos(t) + sin(s) sin(t) = cos(s - t)

Using s =2x and t = x

cos (2x-x) =1

cos (x) =1

We know this occurs at 0, 2pi, 4 pi etc

x = 2* pi* n  where n is an integer

r-ruslan [8.4K]

Answer:

P(X=700) =0.35*700 -76= 169

Step-by-step explanation:

For this case we have the following profit function:

P(X) = 0.35 X -76

And we are interested on find the profit after selling 700 pretzels, so we just need to replace X=700 into the profit function like this:

P(X=700) =0.35*700 -76= 169

The profit function is on the figure attached. We see that for 0<X<217 we have negative profits, and for X>217 we will have positive values for the profit. And also we can see that for X=700 we have a profit of approximately 169.
