Answer:

C.)  f(x) = −4x + 200

Step-by-step explanation:

Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.

In other words, the easiest way to solve this problem is to check the answers against the given data.

_____

If you want to write the equation from scratch, you need to find the slope. That is ...

 (change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4

This matches only one answer, but you can go on to finish the equation by starting with point-slope form:

 y -192 = -4(x -2)

 y = -4x +8 +192 . . . . add 192, eliminate parentheses

 y = -4x + 200 . . . . matches choice C.)

How can I calculate if a given decimal is rational or irrational. please help I forgot.
dalvyx [7]
Well, a rational decimal is like a simple 3.1 or 4.5. It just cuts off easily. Another example would be a repeating decimal like 3.333333...


An irrational decimal is like 3.1415682983523576294875 with no pattern or cutoff point.


Sorry if I am wrong.

URGENT WILL GET 20 and Brainlest
My name is Ann [436]

<em><u>The polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is:</u></em>

f(x) =  -0.04x^2 + 18x + 75

<em><u>Solution:</u></em>

<em><u>The cost of distributing by train can be modeled as:</u></em>

-0.07x^2 + 40x - 105

<em><u>The cost of distributing by truck can be modeled as:</u></em>

-0.03x^2 + 22x - 180

where x is the number of tons of product distributed

To find: Difference between the cost of distributing by train and the cost of distributing by truck

Difference = cost of distributing by train - cost of distributing by truck

Let f(x) = difference in cost between trains & trucks

f(x) = (-0.07x^2+40x-105) - (-0.03x^2 +22x - 180)

f(x) = -0.07x^2 + 40x -105 + 0.03x^2 -22x + 180

Combine\ the\ like\ terms\\\\f(x) = -0.07x^2 +0.03x^2 + 40x - 22x +180-105\\\\Add\ the\ like\ terms\\\\f(x) =  -0.04x^2 + 18x + 75

Thus polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is found

Find the value of x. A. 53–√ m B. 241−−√ m C. 6 m D. 6+35–√ m
dalvyx [7]

Answer:

<h2>x = 2√41 m</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

a² = b² + c²

where a is the hypotenuse

From the question x is the hypotenuse

So we have

<h2>{x}^{2}  =  {8}^{2}  +  {10}^{2}</h2><h2 /><h2>{x}^{2}  = 64 + 100</h2><h2 /><h2>{x}^{2}  = 164</h2>

Find the square root of both sides

We have the final answer as

<h3>x = 2√41 m</h3>

Hope this helps you
