Step-by-step explanation:
Answer:
y= -3/5x + 2
Step-by-step explanation:
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.
Lets compare both equations so we can explain the reason for it, and see it clearly:
<span>y1 = 5x + 1
</span><span>y2 = 4x + 2
y1 > y2
</span>5x + 1 > 4x + <span>2
</span>To see why that happens we need to solve for x:
5x - 4x > 2 - 1
x > 1
Therefore, the first equation is greater than the second for values of x > 1
12*2+7(x) you need to solve for x
