In any rectangle, the area is given by the product of the width and the length.

Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:

$A(x) = f(x)\cdot g(x) = 3x \cdot 2x = 6x^2$

The production graph of the company is a quadratic graph

The true statements about the production graph are:

When producing 5,000 sets of headphones per week, the weekly earnings is $0.
Producing 2,500 sets of headphones per week will give the maximum amount of weekly earnings.
The maximum possible earnings is about $6,250 per week.
If production is increased from 1,500 to 2,000 sets of headphones per week, then the weekly earnings will also increase

<h3>How to interpret the model?</h3>

To interpret the model, we simply evaluate the options one after the other

<u>Producing 5000 sets weekly</u>

From the graph, we have:

(x,y) = (5000,0)

This means that a weekly production of 5,000 sets of headphones give an earning of $0.

Hence, this option is true

<u>Increased production from 3000 to 4000</u>

From the graph, the function value decreases when x increases from 3000 to 4000.

This means that this option is false

<u>Producing 2500 sets</u>

The production of 2500 sets give a maximum earning of $6250

This means that options (c) and (d) are true

<u>Increased production from 1500 to 2000</u>

From the graph, the function value increases when x increases from 1500 to 2000.

This means that this option is true

Hence, the true statements are: (a), (c), (d) and (e)

Parameter of Statistic

From the question, we understand that the teacher is to calculate the class average.

To calculate the class average, the teacher will use the mean function/formula, which is calculated as:

$Mean = \frac{\sum x}{n}$

Generally, mean is an example of a parameter.

<em>So, we can conclude that the teacher will use parameer</em>

Suppose that the total cost of flatiron TVs is given by the function TC(Q) = 500Q + 300 dollars, where Q is the number of TVs pr

Harrizon [31]

The value of TC(10) is 5300 Dollars

Given function is TC(Q) = 500Q +300 dollars

We need to calculate the value for TC (10)

As we know that the equation given is TC(Q) = 500Q + 300 dollars

Q is the number of TVs produced

Therefore, The value of Q is 10 for TC(10)

Substituting the value of Q

in the total cost of flatiron TVs given by function TC(Q) = 500Q + 300 dollars That Q= 100,

TC(10) = 500(10)+300 dollars

∴ TC (10) = 5000+300 dollars

∴ TC (10) = 5300 dollars

Hence the value of TC(10) is 5300 Dollars
