Answer:

The number of ways are there to paint the four buildings is 48.

Step-by-step explanation:

I) let the first building be any color. Therefore the first building can be painted with any of the 4 colors.

Therefore the first building can be colored in 4 ways.

ii) the second building can be colored in 3 ways since it cannot be colored the

same color as the first building.

iii) the third building can also be colored in 3 ways.

iv) the last building can be colored in 2 ways because it cannot be the same color as the first building or the color of the adjacent building.

Therefore the total number of ways the buildings can be colored = 4 \times 3 \times 3  \times 2 = 48.

Point A location is (9,1) and dilated by a scale factor is r =2 what are the coordinates for point A
Sloan [31]
<h3>Answer:  (18, 2)</h3>

We find this answer by multiplying the original coordinates by the scale factor 2.

The old x coordinate 9 doubles to 9*2 = 18, which is the new x coordinate.

The old y coordinate 1 doubles to 1*2 = 2, which is the new y coordinate.

The dilation rule can be stated as (x,y) \to (2x,2y), which means (9,1) \to (18,2)
