A sports team of 11 students is to be constituted, choosing at least 5 from class XI and at least 5 from class XII. if there are 20 students in each of these classes, in how many ways can the team be constituted. What is the importance of sports in one's life ?

Use a graph paper for this question. (Take 2 cm = 1 unit on both x and y axes) Reflect points B(2,3), C(1,1), D(2,0) on the y-axis and write down their coordinates. Name the images as B', C', D' respectively.

A high tension wire is at a high potential with respect to a wire which is well grounded called Earth wire. You must have seen such wires stretched parallel to roads. There is a high tension wire between two points A and B. 1 km apart. The distance between HT wire and earth wire is 1 m. The resisatnce of the HT (and also the earth wire) is 1 Omega//m . This wire is at a potential of 11 KV at point A w.r.t. to earth wire. and its is carrying 1 A current which returns back to the generator by through the earth wire. This wire is quite a thick wire. There is a sign board at a pole over which this wire is stretched reading DANGER, 11 KV. You might thick what would happen if one touched this wire. Will one feel a shock or not. Well ! it depends on whether the current through our body exceeds a particular valuem which we may call CRITICAL CURRENT. If the above question find the current through the bird.

Consider matrix A=[a_(ij)]_(nxxn) . Form the matrix A-lamdal, lamda being a number, real of complex. A-lamdal=[{:(a_11-lamda,a_12,...,a_(1n)),(s_21,a_22-lamda,...,a_(2n)),(...,...,...,...),(a_(n1),a_(n2),...,a_(n n)-lamda):}] Then det (A-lamdaI)=(-1)^n[lamda^n+b_1lamda^(n-1)+b_2lamda^(n-2)+...+b_(n)] . An important rheorem tells us that the matrix A satisfies the equation X^n+b_1x^(n-1)+b_2x^(n-2)+...+b_2=0. This equation is called hte characteristic equation of A. For all the questions on theis passeage, take A=[{:(1,4),(2,3):}] Which of the follwing is inverse fo A ?
