The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix
Matrix AB ( 0,-2/1,0/1,-2)
Answer:
![1\ h\ 8\ min](https://tex.z-dn.net/?f=1%5C%20h%5C%208%5C%20min)
Step-by-step explanation:
we know that
Hunter was biking for 2 hours 20 minutes and covered 35 miles
so
using proportion
Find out how long would it take him to cover 17 miles on this bike
Remember that
1 h=60 min
2 h 20 min=2(60)+20=140 min
Let
x -----> the time to cover 17 miles
![\frac{140}{35}=\frac{x}{17}\\\\x=17(140)/35\\\\x=68\ min](https://tex.z-dn.net/?f=%5Cfrac%7B140%7D%7B35%7D%3D%5Cfrac%7Bx%7D%7B17%7D%5C%5C%5C%5Cx%3D17%28140%29%2F35%5C%5C%5C%5Cx%3D68%5C%20min)
therefore
![68\ min=1\ h\ 8\ min](https://tex.z-dn.net/?f=68%5C%20min%3D1%5C%20h%5C%208%5C%20min)
