The vector u = (3900, 5300) gives the number of units of two models of laptops produced by a company. The vector v = (2000, 1100) gives the prices (in dollars) of the two models of laptops, respectively. Identify the vector operation used to increase revenue by 5%.

Best ResponseYou've already chosen the best response.1right, but the vector itself is an arrow with a slope of y/x... its component parts

Best ResponseYou've already chosen the best response.0ok I gotcha... so the 3900 laptops cost 2000

Best ResponseYou've already chosen the best response.1i cant parse the question tho... how much revenue was made in order to know how much 5% of an increase is....

Best ResponseYou've already chosen the best response.1revenue = number sold * price per unit right?

Best ResponseYou've already chosen the best response.0uhm.. idk it doesn't say... but yes revenue does equal that A) u.(1.05)llvll B) 1.05(u.v) C) 1.05llu.vll D) 1.05llull.v E) 1.05(u+v)

Best ResponseYou've already chosen the best response.1that helps :) 1.05 is the amount you would normal multiply by to find the total paid for something..

Best ResponseYou've already chosen the best response.1B makes no sense; since dpt product doesnt produce another vector..

Best ResponseYou've already chosen the best response.1A makes no sense since you cant dot product to a number

Best ResponseYou've already chosen the best response.0right....I still don't really get the 1.05 thing but that's ok I guess

Best ResponseYou've already chosen the best response.1c is asking for the magnitude of a scalar number which is pointless

Best ResponseYou've already chosen the best response.1E is the only one that makes sense to me as far as vectot operations go

Best ResponseYou've already chosen the best response.0B makes the most sense to me. (u.v) would be the revenue (the quantities of each laptop produced times that laptop's price). So 1.05*(u.v) would increase the revenue by 5%.

anonymous

Best ResponseYou've already chosen the best response.0Unit analysis comes in handy here. u.v = <quantity, quantity> . < money/quantity, money/quantity> = (quantity * money/quantity) + (quantity * money/quantity) = money u+v = <quantity, quantity> . < money/quantity, money/quantity> = <quantity + money/quantity, quantity + money/quantity> Which doesn't really make sense for revenue to be a vector.

Best ResponseYou've already chosen the best response.1doesnt (u.v) represent a vector produced from a scalar amount tho? not quite sure how to read the notation
