Answer:
D
Step-by-step explanation:
Recall that for a function 
such that 
, where 
is the Domain and 
is the Codomain, the function has a inverse, if and only if, 
exist an unique 
such that 
.
Therefore, the inverse of for 
is
==============================================
The reason why I did this is because x represents the number of hours worked. 30 is the flat rate and the customer needs to spend less than $75 so I put the less than sign
The total surface area of the cone is 542.592 square mm
<h3>Total surface area of a cone</h3>
The formula for calculating the total surface area of a cone is expressed as:
TSA = πr(r + l)
where
r is the radius of the cone
l is the slant of the cone
Given the following parameter
l = 13.6mm
r = 8mm
Substitute
TSA = π(8)(8+13.6)
TSA = 3.14(8)(21.6)
TSA = 542.592 square mm
Hence the total surface area of the cone is 542.592 square mm
