A=(1,2) and b=(2, - 1) . Find 4a - 3b
1st carry out the scalar multiplication 4a and -3b
4a =[4(1) , 4(2) ] = (4 , 8)
-3b = [-3(2) . -3(-1)] = (-6 , +3)
4a - 3b = [(4-6) , (8+3)] = (-2 , 11)
5 x 4= 20
When you multiply 5 by four, you get an answer of 20. So, the perimeter of the sticker is 20 inches.
Ok, I think I know what it is saying. I may not be correct but hopefully this gives a idea of a sort.....Im sorry.
The rotation of 90* reflected across the x-axis, so I would think that it is -O. 90(O,-O).
90(O,-O)greater than or equal to ( a units, b units).
