The Pearsonian correlation matrix is necessarily a positive semi-definite matrix (meaning that all its eigenvalues are non-negative) since it is the quadratic form of a real matrix, X ( n, m ). It also implies

function. Computing the Solow residual giver you ∆AA , which is the rate of technological progress. From the question: α=0.2 ; ∆LL=n=0.01; ∆KK=0.07 ; ∆YY=0.05 Taking natural logarithms of the production function gives: ln(Y)=ln(A)+αln(K)+1-αln(L) Taking the first difference of both sides yields: ln(Y)-ln(Y-1)=ln(A)-ln(A-1)+α(lnK-lnK-1)+1-α(ln(L)-ln(L-1)) From here we can use the approximation: lnX-lnX-1≅X-X-1X-1=∆XX Giving: ∆YY=∆AA+α∆KK+1-α∆LL This is the growth

AsDiscussion: In this experiment, ascorbic acid content of apple fruit juice in different conditions was determined by indophenol dye method. The reduced form of ascorbic acid (which is also known as Vitamin C) were determined by this procedure. This was because ascorbic acid is a strong reducing agent. Ascorbic acid was extracted and titration performed in presence of metaphosphoric acid-acetic solution. When titrated with fixed amount of 2, 6-dichlorophenolindophenol red indophenol dye, it was
