Standard form of the polynomial is $x^{7}-2 x^{6}-3 x^{5}+x^{2}+\sqrt{2} x+4$ .

Degree of the polynomial is 7.

Solution:

Given polynomial:

$x^{7}-3 x^{5}+\sqrt{2} x+x^{2}-2 x^{6}+4$

To write this polynomial in standard form:

$x^{7}-3 x^{5}+\sqrt{2} x+x^{2}-2 x^{6}+4$

Standard form of the polynomial is writing x from highest power to lowest power.

Therefore, standard form of the polynomial is

$x^{7}-2 x^{6}-3 x^{5}+x^{2}+\sqrt{2} x+4$

Degree of the polynomial:

The highest power of x in the polynomial is the degree of the polynomial.

Here, the highest power is 7.

Hence the degree of the polynomial is 7.

Segment AB has endpoints A(–4, 6) and B(1, 4). After a dilation, centered at the origin, the image of A is (–6, 9). Without meas

Misha Larkins [42]

Answer:

see the explanation

Step-by-step explanation:

step 1

Find the scale factor of the dilation

Divide the x-coordinate or the y-coordinate of the image by the the x-coordinate or the y-coordinate of the pre-image

$\frac{-6}{-4}=1.5$

$\frac{9}{6}=1.5$

step 2

Multiply the coordinates of point B by the scale factor to obtain the image B'

B'(1.5*1,1.5*4)

B'(1.5,6)
