Which description best explains the domain of (gºf)(x)?

a. the elements in the domain of f(x) for which g(f(x)) is defined

b. the elements in the domain of f(x) for which g(f(x)) is not zero

c. the elements in the domain of g(x) for which g(f(x)) is defined

d. the elements in the domain of g(x) for which g(f(x)) is not zero

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

the answer is 40.
