Which matrix represents the vertices of a rectangle after it is scaled by a factor of 3

C) [  0    12    12   0]

   [  0     0     12   6]

Step-by-step explanation:

The vertices of the given rectangle is (0, 0), (4, 0), (4, 4) and (0, 2)

The scale factor is 3.

We have to multiply each coordinate by 3, we get

(0, 0), (12, 0), (12, 12) and (0, 6)

When we write it in matrix form, we get

[  0    12    12   0]

[  0     0     12   6]

The answer is C.

Thank you.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
