Answer:
a) for all values of x that are in the domains of f and g.
b) for all values of x that are in the domains of f and g.
c) for all values of x that are in the domains of f and g with g(x)≠0
Step-by-step explanation:
a) By definition (f+g)(x)=f(x)+g(x). Then x must be in the domain of f and g.
b) By definition (fg)(x)=f(x)g(x). Then x must be in the domain of f and g.
c) By definition (f/g)(x)=f(x)/g(x). Then x must be in the domain of f and g and g(x) must be different of 0.

Answer:
To find out how much trim you would need for the window, you would need to calculate the Circumference.
Step-by-step explanation:
<u>Circumference</u> is the length around a circle and is calculated using the following formula.

In which C is the circumference and r is the radius. Since we already know the radius all we have to do is plug it into the equation and solve for C.


<u>Answer:</u> The window has a Circumference of 26.389 feet so you would need that amount of trim to fit the area around the window.
