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.
In Linear approximation means you ignore the term 
, if 
is a small number, because then 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:301.59389
Step-by-step explanation:
254.47+47.12389=301.59389
You need to divide by the number 2.3 and 62.50 and then round to the nearest cent
R=4% or .04
a=75
y=a(1+r)^w
y=75(1+.04)^w
y=75 (1.04)^w
