15-x squared. this is because x squared is less then 15 so you would subtract it from 15.

When no more than 110 units are produced, the cost of producing y units is given by C(x).
Maslowich

Producing 73.8 units gives the lowest possible average cost.

The average cost (AC) is the ratio of the total cost to the number of units produced. It is given by:

AC = C(x) / x

AC = (0.2x³ – 24x² + 1514x +30064) / x

AC = 0.2x² - 24x + 1514 + 30064/x

The lowest possible average cost is at AC' = 0. Hence differentiating the average cost, gives:

AC' = 0.4x - 24 - 30064/x²

0.4x - 24 - 30064/x² = 0

0.4x³ - 24x² - 30064 = 0

Solving the cubic polynomial gives:

x = 73.8 units

Therefore the lowest possible average cost is when 73.8 units are produced.

!!! PLEASE HELP FAST !! <br><br> please help me with one a two :)
yan [13]

Answer:

<h3>Question 1</h3>

<u>Function given:</u>

  • y = x² + 4x - 4

<u>In the vertex form:</u>

  • y = x² + 4x + 4 - 8 = (x + 2)² - 8

Axis of symmetry is the vertical line passing through the vertex.

<u>The vertex is</u>

  • (-2,-8)

<u>Axis of symmetry is </u>

  • x = -2

<u>y- intercept is </u>

  • x = 0 ⇒ y = -4, so the point (0, -4)

<u>Two other points are</u>

  • x = 1 ⇒ y = (1 + 2)² - 8 = 9 - 8 = 1, the point is (1, 1)
  • x = -1 ⇒ y = (-1 + 2)² - 8 = 1 - 8 = -7, the point is (-1, -7)

<em>See the graph with all the points plotted</em>

<h3>Question 2</h3>

<u>Function given:</u>

  • y + 2x² - 4x - 6 = 0

<u>In standard form:</u>

  • y = -2x² + 4x + 6

<u>In vertex form:</u>

  • y = - 2x² + 4x - 2 + 8 = -2(x - 1)² + 8

<u>The vertex:</u>

  • (1, 8)

<u>Axis of symmetry is </u>

  • x = 1

<u>y - intercept </u>

  • x = 0 ⇒ y = -2(-1)² + 8 = -2 + 8 = 6, the point is (0, 6)

<u>Two other pints:</u>

  • x = -1 ⇒ y = -2(-1 - 1)² + 8 = -8 + 8 = 0, the point is (-1, 0)
  • x = 2 ⇒ y = -2(2 - 1)² + 8 = -2 + 8 = 6, the point is (2, 6)

<em>The graph is attached with the points plotted.</em>

Which equation can pair with x 2y = 5 to create an inconsistent system?
mr Goodwill [35]

The equation that can be paired with x + 2y = 5 to create an inconsistent system is given by:

2x + 4y = 3.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

An inconsistent system is a system that has no solutions, and it happens when the coefficients of x and y are multiples, and the independent terms are not.

Hence:

x + 2y = 5.

2x + 4y = 3.

Is inconsistent, as the variables are each multiplied by 2, but the independent term is not.
