Derivatives can be calculated from graphed functions.
The values of the derivatives are:
The given parameter is:

Start by calculating the equations of f(x) and g(x)
<u>Graph f(x)</u>
The slopes of f(x) are: 3/2 and -3/2
So, the equations are:


<u>Graph g(x)</u>
The slope of g(x) is: -1/2
So, the equation is:

<u>For x = 1 and x = 2, we have:</u>
So, we have:

Where:
and 
becomes

Open brackets

Differentiate

So:


For x = 3, we have:

Where:
and 
becomes


Differentiate

Substitute 3 for x

Hence, the values of the derivatives are:
,
and

they sell 4 and more than10 for a total of at least 14 tons
the mine extracts 2 ton per hour
so 14/2 = 7 hours a day minimum
so the inequality should be x>7
4000000/6000=666.67
(1+r)^200=666.67
ln (1+r)^200=ln 666.67
200 ln (1+r)=ln 666.67
e^ln (1+r)=e^.03251145
1+r=1.0330457
r=0.0330457, or 3.30457% APR
