Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x9+13 f - 1 ( x ) = x 9 + 1 3 is the inverse of f(x)=9x−3 f ( x ) = 9 x - 3

Answer:
y = 54
x = 36
Step-by-step explanation:
Using tan x or y = opp/adj
60.7 because you add all the sides together
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal
(a)
= , substitute values
= ( cross- multiply )
13.23AB = 111.132 ( divide both sides by 13.23 )
AB = 8.4
(b)
= , substitute values
= ( cross- multiply )
6.3DF = 54.243 ( divide both sides by 6.3 )
DF = 8.61
