Best ResponseYou've already chosen the best response.0ok and can u tell me how do i write the recipocal of the average

anonymous

Best ResponseYou've already chosen the best response.0reciprocal of a number x is 1/x. the reciprocal is a number, which when multiplied by x, gives you 1. 1 is called the multiplicative identity. so, when you multiply x times 1/x, you get x/x = 1 similarly, what is the reciprocal of the number (x+y)/2 ?

Best ResponseYou've already chosen the best response.0ok i got it its 2/(x+y)

Best ResponseYou've already chosen the best response.0and one more quesion, for the same numbers x and y, write an expresiion for their average of their recipocals how do i do that

Best ResponseYou've already chosen the best response.0x/1 and y/1 is that right

anonymous

Best ResponseYou've already chosen the best response.0so if you multiply x times x/1 you will get 1? are you sure?

Best ResponseYou've already chosen the best response.0im srry 1/x and 1/y

Best ResponseYou've already chosen the best response.0okay good. so now you have two numbers 1/x and 1/y. what is their average?

anonymous

Best ResponseYou've already chosen the best response.0no. thats wrong. the average of two numbers a and b is (a+b)/2 so what is the average of two numbers 1/x and 1/y?

anonymous

Best ResponseYou've already chosen the best response.0okay. good. that is your answer. you can simplify the expression further if you want, but that is the answer to your question. 1/x+1/y = (x+y)/xy so (1/x+1/y)/2 = (x+y)/2xy
