WebbCorrect option is A) Given that, points P(3,2,−4),Q(5,4,−6) and R(9,8,−10) are collinear. Q must divide line segment PR in some ratio externally and internally. We know that, Co-ordinates of point P(x,y,z) that divides line segment joining (x 1,y 1,z 1) and (x 2,y 2,z 2) in ratio m:n is (x,y,z)=( m+nmx 2+nx 1, m+nmy 2+ny 1, m+nmz 2+nz 1) WebbThe centromere links a pair of sister chromatids together during cell division. This constricted region of chromosome connects the sister chromatids, creating a short arm (p) and a long arm (q) on the chromatids. During mitosis, spindle fibers attach to the centromere via the kinetochore.. The physical role of the centromere is to act as the site …

Area of triangle PQR = 1/2 [ x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2) ] Here x1 = −1.5 , y1 = 3 x2 = 6 , y2 = −2 x3 = −3 , y3 = 4 Putting values Area of triangle PQR = 1/2 [ (−1.5)(−2 – 4) + 6(4 – 3 ) + (−3)(3 – (−2)) ] = 1/2 [ −1.5(−6) + 6(1) + … WebbThe term collinear is the combined word of two Latin names ‘col’ + ‘linear’. ‘Col’ means together and ‘Linear; means line. Therefore, collinear points mean points together in a single line.
