A company determined that the marginal​ cost, C' (x )of producing the xth unit of a product is given by C' (x )= x^3- 6x. Find t
Rashid [163]

Answer:

C(x) = \frac{x^4}{4}-3x^2+3,000

Step-by-step explanation:

The marginal cost function, C'(x), is the derivate of the cost function, C(x).

Therefore, we can obtain the cost function by finding the integral of the marginal cost function:

C(x) = \int\ {C'(x)} \, dx \\C(x) = \int\ {(x^3-6x)} \, dx \\C(x) = \frac{1}{4} x^4-3x^2+a

Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:

C(x) = \frac{x^4}{4}-3x^2+3,000

It takes Bruce 12 h to complete his training. It takes Oliver approximately 2 days, 2 h, and 15 min to complete his training. Ho
Bond [772]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

1\ day= 24\ hours

1\ hour=60\ minutes

we have

2\ days, 2\ h,\ and\ 15\ min

<u><em>Convert days to hours</em></u>

2\ days=2(24)=48\ hours

<u><em>Convert minutes to hour</em></u>

15\ min=15(1/60)=1/4=0.25\ h

so

2\ days, 2\ h,\ and\ 15\ min=(48)+(2)+(0.25)=50.25\ h

therefore

Oliver completed his training work in 50.25 hours
