-Find the value of k, when the distance between the points (3, 2k) and (4, 1) is 10 units400 nd 1500 resnectively, find its mean. |

Answer» Distance=√10 D=√(x1-x2)^2+(y1-y2)^2 √(4-3)^2+(1-2k)^2 = √10 Taking squares,1+(1-2k)^2 =10 (1-2k)^2=9 Taking square root,1-2k=3 or 1-2k=-3 2k=-2 or 2k=4 k=-1 or k=2 |
