Which statement about the polynomial function g(x) is true?

yKpoI14uk [10]

When leading coefficient is 1 , the root will be an integer for g(x) = 0

Option 4 is the right answer.

<h3>What is a Polynomial Function ?</h3>

Functions of independent variable in which the variable can appear more than once with different powers.

$\rm g(x) = a_n x^n + a_{n-1}x^{n-1} + ................+ a_o$

Let this represents the polynomial function

where $\rm a_n \; is\;the \;leading \; coefficient \; a_o \; is \;the\;last \;term$

Then the according to rational root theorem ,

The root of the function is given by

$\rm \dfrac{p}{q} = \dfrac{factor \;of\; the\; last\; term}{factor \;of \;the\; leading coefficient}$

So when leading coefficient is 1 , the root will be an integer for g(x) = 0

Option 4 is the right answer.

An isosceles trapezoid has base angles 45 and bases of lengths 9 and 15 the area pf the trapezoid is

Nadusha1986 [10]

Tangent 45 = height / 3
height = 3 * tan (45)
height = 3 * 1
height = 3

<span>Trapezoid area = ((sum of the bases) ÷ 2) • height
</span>
<span>Trapezoid area = (9 + 15) /2 * height

</span><span>Trapezoid area = 12 * 3

</span><span>Trapezoid area = 36

The identification code on a bank card consists of 1 digit followed by 2 letters. The code must meet the following conditions: T

jasenka [17]

Answer:

For the code we have 3 selections.

The first selection is a digit that must be odd, so the options are {1, 3, 5, 7 ,9}

So we have 5 options.

The second selection is a letter from the set of all the letters (27) minus the set of the vowels (5)

So here we have 27 - 5 = 22 options

The third selection is also a letter from the previous set, but because each letter can be used only one time, and in the previous selection we already selected one of the letters, in this selection we have a letter less than in the previous selection.

Here we have 22 - 1 = 21 options.

The total number of combinations (of possible codes) is equal to the product of the number of options for each selection:

C = 5*22*21 = 2310.

There are 2310 different possible codes

Square root of 4×-1=5

borishaifa [10]

Answer:3/2

how i did this

 Add 11 to both sides.

4x=5+1

Simplify 5+15+1 to 66.

4x=6

Divide both sides by 4

x= 6/4

Simplify 6/4 to 3/2

Awnser

x=3/2

Sorry if not helpful just trying my best :)
