This paper will help you in upcoming ISC Exam 2019. Question 17. [4] (a) If A, B, C are three non-collinear points with position vectors \(\vec{a}, \vec{b}, \vec{c}\) respectively, then show that the length of the perpendicular from C on AB is \(\frac{|(\vec{a} \times \vec{b})+(\vec{b} \times \vec{c})+(\vec{c} \times \vec{a})|}{|\vec{b}-\vec{a}|}\) Or (b) Show that the four points A, B, C and D with position vectors \(4 \hat{i}+5 \hat{j}+\hat{k},-\hat{j}-\hat{k}, \hat{3} \hat{i}+9 \hat{j}+4 \hat{k} \text { and } 4(-\hat{i}+\hat{j}+\hat{k})\) respectively, are coplanar. Find: (i) Marginal cost function (ii) Average cost function (b) Find the coefficient of correlation from the regression lines: x – 2y + 3 = 0 and 4x – 5y + 1 = 0. Shaded region is the required feasible region and comer points of bounded feasible region are: O(0, 0), B(12, 6), C(20, 0) and D(0, 10) At O(0, 0), Z = 0 + 0 = 0 At C(20, 0), Z = 20 × 80 + 0 = 1600 At B(12, 6), Z = 12 × 80 + 120 × 6 = 1680 → Maximum At D(0, 10), Z = 0 + 120 × 10 = 1200 Hence, maximum profit can be made by manufacturing 12 teaching aids of type A and 6 teaching aids of type B.
