Mathematics
1 answer:
n200080 [17]2 years ago

Answer:

Option 2: 27 is the correct answer.

Step-by-step explanation:

Given functions are:

f(x) = x^2-2\\g(x) = 4f(x) - 1

As we can see that the function g(x) in written in terms of f(x), first of all we have to find g(x) by putting the value of f(x) in g(x)

So putting f(x) = x^2-2 in g(x)

g(x) = 4(x^2-2)-1\\= 4x^2-8-1\\=4x^2-9

As g(-3) has to be found, putting x=-3 in g(x)

g(-3) = 4(-3)^2-9\\= 4(9)-9\\=36-9\\=27

Hence

Option 2: 27 is the correct answer.

The cost function in a computer manufacturing plant is C(x) = 0.28x^2-0.7x+1, where C(x) is the cost per hour in millions of dol
Licemer1 [7]

9514 1404 393

Answer:

  $562,500 per hour

Step-by-step explanation:

The cost will be a minimum where C'(x) = 0.

 C'(x) = 0.56x -0.7 = 0

  x = 0.7/0.56 = 1.25

The cost at that production point is ...

  C(1.25) = (0.28×1.25 -0.7)1.25 +1 = -0.35×1.25 +1 = 0.5625

The minimum production cost is $562,500 per hour for production of 1250 items per hour.

_____

<em>Additional comment</em>

This is different than the minimum cost <em>per item</em>. This level of production gives a per-item cost of $450. The minimum cost per item is $358.30 at a production level of 1890 per hour.
