From the identity: 


the inverse of f is g such that f(g(x))=x,
we must find g(x), such that 
![\frac{1}{cos[g(x)]}=x](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bcos%5Bg%28x%29%5D%7D%3Dx%20)
thus, 
![cos[g(x)]= \frac{1}{x}](https://tex.z-dn.net/?f=cos%5Bg%28x%29%5D%3D%20%5Cfrac%7B1%7D%7Bx%7D%20)

Answer: b. g(x)=cos^-1(1/x)

Hello!</h2>
The answer is:
The correct option is
a) 
<h2>
Why?</h2>
Since a right triangle is formed, we can calculate the resultant force using the Pythagorean Theorem which states that:

Where,
c, is the hypothenuse.
a, is one triangle leg.
b, is the other triangle leg.
So, we are given the information:


So, calculating the resultant force (hypothenuse), we have:

Hence, the expression that would find the result velocity is:
a) [tex]Resultant=\sqrt{22^{2} +4^{2} }[/tex]

Answer:

Step-by-step explanation:
Using the midpoint formula,  , we can find the coordinates that represents the position of the ship at noon.
, we can find the coordinates that represents the position of the ship at noon.
Let  (given on the coordinate plane)
 (given on the coordinate plane)
 (given also)
 (given also)
Plug in the values into the formula and solve as follows:




Position of the ship at noon is best represented at 
 
        
             
        
        
        
Cut the figure into two parts 
area of a rectangle is length x width 
10x5=50m
2x4=8 
add them together 
50+8=58
