Kelly used 1.75 yards of fabric in each dress she made
9 x 37 = 333
8 x 37 = 296
333 - 296 = 37
It is shown that by looking at the formula for the volume of a cylinder (we assume that the trash can is cylindrical):
V = pi*r^2*h
We can conclude that the volume of the trash can is directly proportional to its radius and height. To wrap up, the volume would increase as the radius of the trash can's base, and its height would be increased as well.
Answer:

Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0.
The derivative of
is
. The derivative of
is
, for example.
The derivative of the ln function:
If we have:

The derivative is

In this problem, we have that:

So
and 
So the derivative to this function is
