- Option : D
- Explanation : The equation of the line joining V and A is given by x = t + 3; y = t + 6; z = 4 - t. Since B and C satisfy this, all the four points are collinear. We can find that t = 0 for A, t = -1 for B, t = -2 for V and t = -3 for C. From these values it is clear that these points lie in the order C, V, B, A. Hence the answer
- Option : C
- Explanation : We have to find the temperature that is same in Mars and Jupiter. Put M = J in the equation (M -100) x 225/150 = J -75 and solve to get 150
18. Which of the following curves are symmetric about the line x = y?
- Option : D
- Explanation : lf the equation of the curve is unaltered, if x is replaced by y and y by x, then the curve will be symmetric about the line x = y.
- Option : D
- Explanation : If (0, 0) is substituted in the equation, we get 0, which is less than 2. So, any point on the same side as that of the origin, should yield a value less than 2, when substituted in the equation. Hence the result
20. Which one of the following is not a linear transformation?
- Option : B
- Explanation : A function F(x, y) x (a, b) is linear if F(ax, ay) = aF(x, y) and F(a+x, b+y) = F(a, b)+ F(x, y). The functions given in options (A), (C), (D) satisfy these two conditions but option (B) doesn't
