Answer:
Option D.
Step-by-step explanation:
To find the inversion of a function follow the following procedure
1) Replace x with y in the function and clear y
------> 
2) Check. The range of f(x) is the domain of 
.
So if f(a) = b, this means that 
= a.
Is fulfilled. Therefore 
is the inverse of 
Answer:
352
Step-by-step explanation:
originally 351.86 but 352 when rounded
Answer: PN= 20 in.
Step-by-step explanation:
Given: In triangles PMN and QSR :
Length of P N ≅ Length of RQ (1) [ '≅' → Sign of congruence]
Length of QS ≅ Length of PM
Length of MN ≅ Length of RS
By SSS congruence rule
ΔPMN ≅ ΔQSR
Since Length of QR =20 in. [Given]
From (1)
Length of PN= 20 in. [Congruent means exactly equal]
7.75% of 20
.0775 (20) = 1.55....its not A
7.75% of 25
.0775(25) = 1.94....not B
7.75% of 10
.0775(10) = 0.775 (BINGO...here it is)
7.75% of 18
.0775(18) = 1.40..not D
