Not proportional there is no pattern and one of the point is negative and the rest is positive so it makes no sense

Answer:

Not proportional.

I looked at the following ordered pairs:

(-2,-27)

(1,12)

(4,57)

(10,147)

Please see I have the points correct.

Thank you kindly.

Step-by-step explanation:

To see if it is proportional, we just need to see if the following equality holds:

\frac{-27}{-2}=\frac{12}{1}=\frac{57}{4}=\frac{147}{10}?

I'm going to put each fraction into my calculator.

13.5=12=14.25=14.7 which is totally not true so this relationship is not proportional.

Part I)
 
The module of vector AB is given by:
 lABl = root ((- 3) ^ 2 + (4) ^ 2)
 lABl = root (9 + 16)
 lABl = root (25)
 lABl = 5

 Part (ii)
 The module of the EF vector is given by:
 lEFl = root ((5) ^ 2 + (e) ^ 2)
 We have to:
 lEFl = 3lABl
 Thus:
 root ((5) ^ 2 + (e) ^ 2) = 3 * (5)
 root ((5) ^ 2 + (e) ^ 2) = 15
 Clearing e have:
 (5) ^ 2 + (e) ^ 2 = 15 ^ 2
 (e) ^ 2 = 15 ^ 2 - 5 ^ 2
 e = root (200)
 e = root (2 * 100)
 e = 10 * root (2)

Which of the following is a true polynomial identity​
zhuklara [117]

Answer:

It's a.

Step-by-step explanation:

(a - 2b)^2 + 8ab

= a^2 - 4ab + 4b^2 + 8ab

= a^2 + 4ab + 4b^2.

((a + 2b)^2 = a^2 + 4ab + 4b^2.

What effect does a scale factor equal to 1 have on the dimensions of the image being scaled?
FromTheMoon [43]

The scale factor equal to 1 will have No Effect on the dimensions of the image being scaled .

In the question ,

it is given that ,

the scale factor is = 1.

we have to find the effect of change ;

we know that ,

when the value scale factor is greater than 1 , then dimensions of new image is larger than original .

when the value of scale factor is 1 , then there is no change in the dimensions of the image .

when the value of scale factor is less than 1 , then the dimensions of new image is smaller than the original .

Therefore , if the scale factor is 1 , then there is no change in the dimensions of the image .

USPshnik [31]

Answer:

C. m+n/2

Step-by-step explanation:

Factor out the 3 in the numerator and apply the difference of squares, factor out the 6 in the denominator, and reduce where applicable. It'll all cone out to look like option C.
