ASAP PLEASE ANSWER quadrilateral ABCD is dilated at center (0,0) with scale factor 1/2 to form quadrilateral A'B'C'D'. wha is th
zhenek [66]

Answer:

|A'B'|=\sqrt{5}

Step-by-step explanation:

The points A and B have coordinates at (0,4) and (4,2) respectively.

The distance formula can be used to find the length of AB.

|AB|=\sqrt{(4-0)^2+(2-4)^2}

|AB|=\sqrt{(4)^2+(-2)^2}

|AB|=\sqrt{16+4}

|AB|=\sqrt{20}

|AB|=2\sqrt{5}

Since quadrilateral ABCD was enlarged with  a scale factor of \frac{1}{2}.

The length of A'B' is

\frac{1}{2}|AB|

=\frac{1}{2}\times2\sqrt{5}

\therefore |A'B'|=\sqrt{5}

A matrix contains 60 elements. Which of the following cannot equal the number of rows of the matrix?
avanturin [10]

<span>Given:

Matrix = 60 elements</span>

 

<span>To solve this, we need to take into account that each row must contain the same number of elements. So, we need to find which of the options do not divide evenly into 60 (the options are 30, 60, 10, and 18).

So we check each of the choices to see if 1 of them divides evenly with 60.

60 / 60 = 1 (divides evenly)</span>

60 / 30 = 2 (divides evenly)

<span>60 / 10 = 6 (divides evenly)
</span>60 / 18 = 3.3.3333333333333333333333333333333 (does not divide evenly)

Therefore, 18 cannot equal the number of rows of the matrix.
