Let u = <-4, 1>, v = <-1, 6>. Find -2u + 4v
Maksim231197 [3]

Answer:

<4,22>.

Step-by-step explanation:

This question involves the concepts of addition and scalar multiplication of vectors. It is given that the vector u = <-4, 1> and v = <-1, 6>. To find -2u, simply multiply -2 with the elements of u. This will give:

-2u = <-4*-2, 1*-2> = <8, -2>.

Similarly:

4v = <-1*4, 6*4> = <-4, 24>.

Hence,

-2u + 4v = <8, -2> + <-4, 24> = <8-4, -2+24> = <4,22>.

So the correct answer is <4,22>!!!

Find the product .-2 [7 -4 0]
Makovka662 [10]
It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0]                                           solving: [-14 8 0] [-3 0 5]
                                                                           [42+0+70     -24+0+40   0+0+0]  
  [-14 8 0] * [-3 0 5] = [112 0 -30]                           = [112  16  0]
                                                                          [112  16  0]*[6  2  1]
[112 0 -30]* [6 2 1] = [1008 114 0]                  [672+224+112    96+32+16   +0]
                                                                          =[1008  114  0].
