MAT-12.NO.18

BPSS-MAT-NO logo 12th Grade (MAT) Targeted Standard  
 (NO) Number and Operations 
Learners will develop a foundational understanding of the number system, operations, and computational fluency to create connections and solve problems within and across concepts.
MAT-12.NO.18 Multiply a vector by a scalar.
  • Represent scalar multiplication graphically by scaling vectors and possibly reversing their direction. Use the components to perform scalar multiplication (e.g., as c(vx, vy) = (cvx , cvy)).
  • Compute the magnitude of a scalar multiple cv using ||cv|| = |c|v.
  • Compute the direction of cv knowing that when |c|v ≠ 0, the direction of cv is either along v (for c > 0) or against v (for c < 0).
