1. how much time will you save on a ten mile trip if you travel at 60 mph rather than at 55 mph?

60/10 = 6

 so it would take 6 minutes to drive 10 miles

55/10 = 5.5 so it would take 5 and a half minutes to drive 10 miles

6-5.5 = 0.5 so it would save you 30 seconds

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
