Find the polynomial function with leading coefficient 3 that has the given degree and zeros.

Gnoma [55]3 years ago

So you know that there are three zeroes, and that it is to the 3rd degree, so you know that there are going to be 3 terms initially.

(x+2)(x-1)(x-4) - You can multiply by 3 at the end

x^2 - x + 2x -2
(x^2 + x - 2)(x - 4)

x^3 - 4x^2 + x^2 - 4x - 2x + 8
x^3 - 3x^2 - 6x + 8

f(x) = 3x^3 - 9x^2 - 18x + 24

How many units of 1/8 compose 3/4? PLZ Help! <br><br> this might be an easy answer
trasher [3.6K]
There is two 1/8's to make 1/4. This is proven by the following example:
1/8 + 1/8 = 2/8.
2/8 (simplified) = 1/4.
Given the information above, we can safely figure out this problem.
Since 2/8 make 1/4, and we're looking for 3/4, multiply 2/8 by 3.
2/8 x 3 = 6/8.
It will require 6 total 1/8's.
I hope this helps!

What does the value of x have to be so that
Natali5045456 [20]

The value of x is 5

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

<em><u> The slope of a line is given by formula: </u></em>

Slope = \frac{ y_2-y_1}{x_2-x_1}

From given,

slope = \frac{11}4}\\\\(x_1, y_1) = (x, -7)\\\\(x_2, y_2) = (-1, 4)

<em><u>Substituting the values we ge</u></em><em><u>t,</u></em>

\frac{11}{4} = \frac{4+7}{-1-x}\\\\-11 - 11x = 11 \times 4\\\\-11-11x = 44\\\\11x = -11-44\\\\11x = 55\\\\x = 5

Thus the value of x is 5

What is 3 × 100 + 3 × 1 + 4 ×( 1/10) + 5 ×( 1/100) + 7 ×(1/1000) ?
Natalka [10]
The answer is:  [B]:  " 303.457 " .________________________________________
Explanation:  Use the "order of operations"; which is represented by the mnemonic device:

PE MD AS ;  (Please excuse my dear Aunt Sally/Susan);

also, known as:  BE MD AS ;  (Be excused, my dear Aunt Sally/Susan);

The operations performed are done in order of first to last;  the "P" stands for parentheses" ;  The "B" stands for "brackets".

The "MD" stands for "multiplication, then division";  As per the mnemonic device, there should be an "arrow from left to right over the "MD" ; which means that when both Multiplication AND division occurs; the operations are perform in order from left to right, as they occur in the problem being solved.

The "AS" stands for "addition, then subtraction".  Again, as per the mnemonic device, there should be an "arrow from left to right over the "AS" ; which means that when both addition AND subtraction occurs; the operations are perform in order from left to right, as they occur in the problem being solved.
___________________________________________________________
We are given: 
_________________________
3 × 100 + 3 × 1 + 4 ×( 1/10) + 5 ×( 1/100) + 7 ×(1/1000) ?
___________________________________________
 Using the "order of operations" ;  we can rewrite this problem as:

(3*100) + (3*1) + [ 4*(1/10) ]  + [5*(1/100) + [7*(1/1000)] ;

Note that both multiplication and division take priority over addition, according to the "order of operations".
_______________________________________________
Now, rewrite:  300 + 3 + (4/10) + (5/100) + (7/1000).
_______________________________________________
Change the "(4/10)"  to:   ?/ 1000 ;  "4/10" = (4*100)/(10*100) = 400/1000 ;

Change the "(5/100)" to:  ?/1000 ;  "5/10" = (5*10)/(100*10) = 50/1000  ;

____________________________
Now, rewrite:   300 + 3 + (4/10) + (5/100) + (7/1000) =

            300 + 3 + (400/1000) + (50/1000) + (7/1000) =

            303 + [ (400 + 50 + 7) / 1000 =    303 + (457/ 1000) ;

                                                          =  303.457 ;
                                                   which is:  Answer choice:  [B].

The graph of a linear function is shown which word describes the slope of the line the choices and graph is below
aliya0001 [1]
<h2>Answer </h2>

negative

<h2>Explanation </h2>

Let's find the slope of our line using the slope formula:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

where

m is the slope of the line

(x_{1},y_{1}) are the coordinates of the first point on the line

(x_{2},y_{2}) are the coordinates of the second point

From the graph we can get the points (-2, 1) and (2, -1), so x_{1}=-2, y_{1}=1, x_{2}=2, and y_{2}=-1. Let's replace the values in our formula to find m:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{-1-1}{2-(-2)}

m=\frac{-2}{2+2}

m=\frac{-2}{4}

m=-\frac{2}{4}

m=-\frac{1}{2}

The slope of the graph of the linear function is -\frac{1}{2}; since -\frac{1}{2} is a negative number, the slope of the graph is negative.
