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:

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

Find the quotient: (24xy^3-16x^2y^2+32x^2y)/8xy

kolbaska11 [484]

$\cfrac{24xy^3-16x^2y^2+32x^2y}{8xy} = \\ \\ \\ = \cfrac{8xy(3y^2-2xy+4x)}{8xy} = \\ \\ \\ 3y^2-2xy+4x$

Two cars, A and B, are travelling along a straight road and in the same direction. Car B is 20 km

pishuonlain [190]

Answer:

2 o'clock

Step-by-step explanation:

Their 'closing speed' is 60 - 50 = 10 km/hr

they have 20 km between them

at closing speed this will take 20 km / 10 km/hr = 2 hours for the cars to meet....this would be at 14:00 or 2 oclock
