The category of the polynomial 2x³ - 5 + 9x² is a trinomial

<h3>How to determine the category of the expression?</h3>

From the question, we have the following expression that can be used in our computation:

2x^3-5+9x^2

Rewrite this expression properly

So, we have the following representation

2x³ - 5 + 9x²

This expression can be further rewritten as

2x³ + 9x² - 5

The degree of a polynomial is the highest power of the polynomial

In this case, the degree of the above polynomial is 3

As a general rule, a trinomial is any polynomial that has a degree of 3

Hence, the expression is a trinomial

The same charity organization from problem 6 has to pay $4,700 for the ban hall as well as $110 per plate for each ticket sold.

s2008m [1.1K]

Answer:

$T(x) = 4700 + 110x$

Step-by-step explanation:

We are give the following in the question:

Money paid for ban hall = $4,700

Cost of per plate per tickets sold = $110

a) We have to model the total amount spent as a function of the numb tickets sold.

Let x be the number of tickets sold,

Thus, we can find the total amount T(x) as

$T(x) = 4700 + 110x$

is the required equation for total amount when x tickets are sold.

Um estudante fez algumas provas em seu curso e obteve as notas 13, 34, 45, 26, 19, 27, 50, 63, 81,76, 52, 86, 92 e 98 a sua nota

AlladinOne [14]

Answer:

the mean is 54.428571428571<-------( what i think you are looking for )

the median is 51

the modes are 13, 19, 26, 27, 34, 45, 50, 52, 63, 76, 81, 86, 92, 98

Step-by-step explanation:

list all the numbers from greatest to least and the easiest way is to just cross them off left to right until you come up to one or two numbers. if one, that is your median. If two then add them up and divide them by two. We only had one, so the median is 51!

Hope this helped!

Given fraction is
$f(x) = \frac{x^2 + 4x + 3}{x^2 - 9}$

As we know fraction is not defined where denominator is equal to zero.

So let's find where denominator is zero.

$x^2 - 9 = 0$

We can factorize it as $a^2 - b^2 = (a+b)(a - b)$

So we can write given equation as

$(x+3)(x-3) = 0$

So x = 3 or x = -3.

So function is undefined at x = 3 and x = -3.

So option 3 is correct.
