Answer: a) c(x) = 0.124x + 1.1, b) 13 units 
Step-by-step explanation: Revenue function = R(x) = 0.21x
Profit function = p(x) = 0.086 - 1.1
Cost function = c(x) =? 
A)
Recall that profit = total revenue - total cost 
Hence, total cost = total revenue - profit 
c(x) = 0.21x - (0.086x - 1.1) 
c(x) = 0.21x - 0.086x + 1.1
c(x) = 0.124x + 1.1
B)
Break even point is the point where total revenue equals total cost 
R(x) = c(x) 
0.21x = 0.124x + 1.1
0.21x - 0.124x = 1.1
0.086x = 1.1
x = 1.1/0.086
x = 12.79 which is approximately 13 units 
 
        
             
        
        
        
Given:
The right triangle with base 15 and hypotenuse x.
The measure of angle between base and hypotenuse is 28 degrees.
To find:
The value of x.
Solution:
In a right angle triangle,

In the given triangle,




Round the value to the nearest tenth.

Therefore, the value of x is 17.0 units.
