Recall, first off, you sort the terms in descending order, in this case, they already are in descending order.  Then you use the coefficients.  first off you drop down the first value, and take it from there,

\bf p(x)=\underline{3} x^3\underline{-4} x^2\underline{-5} x\underline{+1}\qquad a=2\\\\\\
\begin{array}{r|rrrrrrl}
2&&3&-4&-5&1\\
&&&6&4&-2\\
-&&--&--&--&--\\
&&3&2&-1&\boxed{-1}&\impliedby remainder
\end{array}
\\\\\\
3x^2+2x-1x+\boxed{\frac{-1}{3x^3-4x^2-5x+1}}
\\\\\\
3x^2+2x-x-\frac{1}{3x^3-4x^2-5x+1}

How can you find the area of a polygon that is not one for which your know an area formula? I dont get it at all some one help m
miskamm [114]
"Break into triangles, then add. In the figure on the right, the polygon can be broken up into triangles by drawing all the diagonals from one of the vertices. If you knowenough sides and angles to find the area of each, then you can simply add them up to find the total." -<span>www.mathopenref.com/polygonirregulararea.html</span>

What is the area of this polygon? Enter your answer in the box. units²
Gemiola [76]

Answer:

The area of the polygon is 39\:units^2

Step-by-step explanation:

Sketch the polygon to obtain the figure in the attachment.

The polygon can then be divided into a rectangle and a triangle.

The area of the polygon

=|VE|\times |DE|+\frac{1}{2}\times |DE|\times |AM|

We use the absolute value method to find the lengths

=|3--2|\times |3--3|+\frac{1}{2}\times|3--3|\times |5-2|

=5\times 6+\frac{1}{2}\times 6\times 2

=30+9

=39\:units^2

A sample of 25 provided a sample mean x = 14 and a sample standard deviation s = 4.32.
lys-0071 [83]

The value of the z test statistic will be 2.55.

<h3>What is the z test statistic?</h3>

The z test statistic is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z test statistics is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

A sample of 25 provided a sample mean μ = 14 and a sample standard deviation σ = 4.32.

Then the value of the z test statistic will be

z = (x – μ) / σ

z = (25 - 14) / 4.32

z = 11 / 4.32

z = 2.546 ≈ 2.55

More about the z test statistic link is given below.
