Vectors Quiz

Find the sum of the given vectors: <-1,4>, <6,-2> = [blank_start]<5,2>[blank_end]

Find a + b, 2a + 3b, |a|, and |a-b|. a=<5,-12>, b=<-3,-6> Ans: a+b = [blank_start]<2,-18>[blank_end] 2a+3b = [blank_start]<1,-42>[blank_end] |a| = [blank_start]13[blank_end] |a-b| = [blank_start]10[blank_end]

Find a unit vector that has the same direction as the given vector. -3i + 7j is equal to the unit vector -3/sqrt(58) i + 7/sqrt(58) j.

Find a unit vector that has the same direction as the vector given. 8i - j + 4k

What is the angle between the vector and the positive direction of the x-axis? i + sqrt(3)j = [blank_start]60[blank_end] degrees
