Answer:
0.012
Step-by-step explanation:
Linear approximation says that, 

For a cube the surface area is  .
. 
So the side is 1.0 inch in, the surface area is  square inches.
 square inches.  
In Linear approximation means you ignore the term  , if
 , if  is a small number, because then
 is a small number, because then  will be a very smalle number and that does not contribute much to the error.
 will be a very smalle number and that does not contribute much to the error.  
So the surface area is approximately, 
 
So here, 
The error in the area is approximately, 

So the error is 0.012.

Answer:
f=−35
Step-by-step explanation:
<em>1.Simplify  4×6.5 to 26</em>
f=-26-9
<em>2. Simplify  -26-9 to  -35</em>
f=-35
