Divide x^3-3x^2-10x+24 by x-2
melisa1 [442]
You can do this using synthetic division, which is the easiest way.  If x - 2 = 0, then x = 2.  That 2 will go outside the "box" and the leading coefficients of the terms in the polynomial will go inside the "box".  2    (1   -3    -10    24).  Bring down the first number, the 1.  Multiply that 1 by the 2 to get 2.  Put that 2 up under the -3 and add to get -1.  Multiply that -1 by the 2 to get -2.  Put that =-2 up under the -10 and add to get -12.  Multiply that -12 by the 2 to get -24.  Put the -24 up under the 24 and add to get 0.  That means that x - 2 is a factor of the polynomial.  What's left, the bolded numbers, are the coefficients of a new polynomial that is one degree less than the polynomial you started with.  In other words, when we divide your polynomial by x-2, you get x^2-x-12.

A box contains 10 balls, of which 3 are red, 2 are yellow, and 5 are blue. Five balls are randomly selected with replacement. Ca
VLD [36.1K]

Answer:

The required probability is 0.1.

Step-by-step explanation:

red balls = 3

yellow balls =  2

blue balls = 5

Selected balls = 5

Number of elemnets in sample space = 10 C 5 = 1260

Ways to choose 1 red ball and 4 other colours =  (3 C 1 ) x (7 C 4) = 105

Ways to choose 5 balls of other colours = 7 C 5 = 21

So, the probability is

\frac{105}{1260} + \frac {21}{1260}\\\\\frac{126}{1260}=0.1

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.
