When u multiply a number by its multiplicative inverse (its reciprocal), the product will always be 1....so ur answer is C
Answer:
he gave 3.75 to his friend in dividing
if it is adding it will be 4, hope this helps
Both are D
First one:
f(g(x)) =f(x^2+3) then you x^2+3 is the x you are going to introduce in the function f
f(x^2+3)= sqrroot(x^2+3-3)= sqrroot (x^2) =x
Second:
you need to leave x alone
y = 3x^2 +1
y-1 = 3x^2
(y-1)/3 = x^2
sqrroot ((y-1)/3) = x
sqrroot ((x-1)/3) = h^-1(x)
Hope this helps but I think the answer is 3 connections. But I am not sure.Here is how I got my answer since they said every other computer has a connection then it should be that 1 and 3,3and 5,and 5 and 7 have a connection.That is 3 connections in total.
