The marginal cost of drilling an oil well depends on the depth at which you are drilling; drilling becomes more expensive, per m
sukhopar [10]

Answer:

4,250,000 riyals

Step-by-step explanation:

The total cost of drilling a 500-meter well is the sum of fixed costs (1,000,000 riyals) and variable costs.

By integrating the marginal cost function we get the variable costs function. Evaluating the variable costs function from 0 to 500 meters, gives us the total variable cost.

C(x) =\int\limits^{500}_0 {C(x')} \, dx  =\int\limits^{500}_0 {(4000 + 10x)} \, dx \\C(x)=4000x +5x^2 +c|^{500}_0\\C(500) - C(0) = (4000*500 +5*500^2 +c) - (4000*0 +5*0^2 +c)\\C(500) - C(0) = 3,250,000

Total cost of drilling is:

TC = 3,250,000 + 1,000,000\\TC = 4,250,000\ riyals

Which equations are true?<br>A: -x = -x + x + 0<br>B: -x = 0 + (-x)<br>C: None Of The Above ​
Leto [7]
Answer: B
Explanation: if you look at A and try to combine like terms, you will add the -x on the right side the the one on the left, cancelling out the x on the left. then you have 0=x+0, and unless x=0, it is not true.
With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!
