I'd say it's D. I know the effect is that the money is increased, however I don't know by exactly how much.
Answer:
x(log(x) - 1) + C
Step-by-step explanation:
The formula for the derivative of a logarithm function is:

For your case, the base is 10. Now that we have the derivative, lets use integration by parts. I will be differentiating log(x) and integrating 1:
u = log(x)
du = dx/xlog(10)
dv = 1
v = x
You get:
log(x)x - integral(dx/log(10))
Therefore the answer is:
log(x)x - x/log(10) + C
x(log(x) - 1) + C
Answer:
$20.11 (assuming S325 was meant to be $3.25)
Step-by-step explanation:
50.00 - 5.52 = 44.48
44.48 - 3.25 = 41.23
41.23 -21.12 = 20.11

Answer:

Step-by-step explanation:
There is only one figure in the attached image and the solution (surface area) is as follows:
The shape can be sub-divided into:
1. Rectangle
Dimension: 40 by 35
2. Rectangle
Dimension: 40 by 28
3. Rectangle
Dimension: 21 by 40
4. 2 triangles
Base: 21 and Height: 28
Calculate area of each and add them up to get the surface area of the figure.
1. Rectangle
Dimension: 40 by 35

2. Rectangle
Dimension: 40 by 28

3. Rectangle
Dimension: 21 by 40

4. 2 triangles
Base: 21 and Height: 28

So, the area is:


Factor out 40
