Answer:
[ 0 ]
Step-by-step explanation:
The order of the matrix [ 3 1 1 ] is 1 by 3 and the order of the other matrix is 3 by 1 so this means that the order of the answer matrix is 1 by 1. So we multiply matrices row by columns.
[ 3 1 1 ] × | 2|
| -6|
| 0|
[ 3 × 2 + 1 × -6 + 1 × 0 ]
[ 6 - 6 + 0 ]
[ 0 ]

Answer: C is the correct option
Step-by-step explanation:
In four hours, a hiker in a canyon goes from 892 ft to 256 ft above the canyon floor.
From the above information,
Total distance travelled by the hiker in moving from 892 ft to 256 ft above the Canyon is 256 - 892 = -636 ft
Speed = distance travelled/time
The hiker’s vertical speed is total distance travelled vertically divided by the time it takes to travel the vertical distance. It becomes
-636/4 = –159 ft/h
