The equation connecting C,A and n is  C = 25A - \frac{49990000}{n}

<h3>What is variation?</h3>

Variation is a mathematical term used to show how a quantity behaves when one quantity increases or decreases.

Analysis:

C = AK + M/n

where K and M are constants

when n = 1000, A = 5000, C = 75010

75010 = 5000K + M/1000-----------1

50004 = 10000k + M/200-------------2

solving simultaneously,  K = 25, M = -49990000

C = 25A - 49990000/n

In conclusion, the equation connecting C,A and n is C = 25A - 49990000/n

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto
muminat

Answer:

x = u\cos(v) , y = u \sin(v)

Step-by-step explanation:

For that transformation you just have to use polar coordinates, notice that when you use polar coordinates the radius is constant when the angles varies and the angle is constant when the radius varies. Therefore your transformation would be just

x = u\cos(v) , y = u \sin(v).

Naomi is a songwriter who collects royalties on her songs whenever they are played in
barxatty [35]

Equations can be solved in several ways; one of these ways is the graphical method.

The number of commercials, x, and  the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.

Let:

<em />x \to<em>  commercials</em>

<em />y \to<em> movies</em>

<em />

She earned a total of $300.

This is represented as:

20x + 100y =300

Her songs were played on 3 more commercials than movies.

This is represented as:

x = 3 + y

See attachment for the graphs of

20x + 100y =300

x = 3 + y

From the graph, the lines of both equations intersect at:

x = 5

y = 2

This means that:

  • <em>The number of movies is 2</em>
  • <em>The number of commercials is 5</em>

Geometry math question no Guessing and Please show work
Alexus [3.1K]
The scale factor would be 1/2. For example, coordinate A was (12, 8) before dilation. After dilation, coordinate A was (6, 4.) The coordinates became 2x as small so 1/2 of the orginal shape remain. 12 × 1/2 = 6
