U_n+1=1/U_n where U₁= 2/3First of all, we need to find U₂ and U₃ and so on, up until we notice a pattern in the answers. U₂ = 1/(2/3) = 3/2U...

When marginal costs start to rise, starting at point C, due to diminishing returns, the average variable cost is still decreasing, at point X. The average variable cost will continue to decrease as long a...

The strange situation is a method first used by Ainsworth to assess infant attachment. The infant and mother are observed in a controlled environment and they experience a series of 3-minute stages. The m...

Int() in this case will refer to integralsAnswer is: f(x)=(1-x^2)/(1+x^2)=(2-(1+x^2)/(1+x^2)=-1+2/(1+x^2)=> Int(f(x))=Int(-1+2/(1+x^2))=Int(-1)+2Int(1/(1+x^2))=-x+2tan^-1(x)+C
