A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be c
I am Lyosha [343]

Answer:

the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Given the data in the question;

the distance within 9 miles ⇒ 0 < x > 9

Total costs Q = cx + 4c/( x + 1)

costs should be minimum  ⇒ dQ/dx = 0

⇒ d/dx [ cx + 4c/( x + 1) ] = 0

⇒ ( x + 1)² = 4

take square root of both side

√[ ( x + 1)² ] = √4

x + 1 = 2

x = 2 - 1

x = 1

Therefore, the woman has to live 1 mile from work to minimize the expenses

Brainliest? :(
Svetlanka [38]

Answer:

(f\cdot g)(x)=2x^2+10x+12

(f-g)(x)=-x-1

(f+g)(1)=10

Step-by-step explanation:

\tt f(x)=x+3

\tt g(x)=2x+4

(f\cdot g)(x)=f(x)\cdot g(x)=(x+3)(2x+4)=2x^2+4x+6x+12

=2x^2+10x+12

(f-g)(x)=f(x)-g(x)=x+3-(2x+4)=x+3-2x-4

=-x-1

(f+g)(1)=f(1)+g(1)=1+3+2(1)+4

=4+2+4=10
