|
Answer» P(x)= 2x²+kx-12 P(4)=2(4)²+k(4)-12P(4)=2(16)+k*4-12P(4)=32+4k-12p(4)=-20+4kNow we have to find k;k=-20/4k=-5HENCE,k=-5 P(x) = 2x² + kx - 12 P(4) = 2(4)² + k(4) - 12 0 = 32 + 4k - 12 0 = 20 + 4k -20 = 4k k = -20/4 k= -5 P(x) = 2x² + kx - 12P(4) = 2(4)² + k(4) - 120 = 32 + 4k - 120 = 20 + 4k-20 = 4kk = -20/4k= -5 |

Answer» Here, we need to draw a line AB parallel to line PQ, through point M asshown in Fig. 6.25. Now, AB || PQ and PQ || RSTherefore, AB || RS (Why?)Now, ∠ QXM + ∠ XMB = 180° (AB || PQ, Interior angles on the same side of the transversal XM)But ∠ QXM = 135°So, 135° + ∠ XMB = 180°Therefore, ∠ XMB = 45° (1)Now, ∠ BMY = ∠ MYR (AB || RS, Alternate angles)Therefore, ∠ BMY = 40° (2)Adding (1) and (2), you get∠ XMB + ∠ BMY = 45° + 40°That is, ∠ XMY = 85° First draw a line AB between PQ and RS such that AB||PQ||RS Now, prove that angle mxq + angle xmy = 180 ( angle are in same side of transversal are 180 ) .... 1 Since you know the value of angle mxq (I.e 135°), just put this in (1), You\'ll get to know the value of angle xmy |
