The costs of a company are represented by the function c(x)=2.6x+23,400. its revenues are represented by the function r(x)=2.8x.

find the function that represents the company's profits.

Step-by-step explanation:

we know that

The profit is equal to the revenue minus the cost

Let

P(x) ----> represents the company's profits.

so

we have

substitute the given functions

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
