6. Cross product: A= (2,3,4) B= (2,4,6)

(2,-4,2)

Step-by-step explanation:

If this is for Vector Cross Product:

Cross product of two vectors =  (u1,u2,u3) * (v1,v2,v3) =

(u2v3 - u3v2, u3v1 - u1v3, u1v2 - u2v1) = ((3*6) - (4*4), (4*2) - (2*6), (2*4) - (3*2) =

(2,-4,2)

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
