A perspective projection produces realistic views.
|

| A. |
C hides A and B, if viewed from V
|
| B. |
C hides A but not B, if viewed from V
|
| C. |
A hides B but not C, if viewed from V
|
| D. | B hides A but not C, if viewed from V |
|
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 Band 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

| A. | 1 + x + y = 0 |
| B. | | x | + | y | = 9 |
| C. | y=x3 |
| D. | Both (a) & (b) |
|
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.

| A. |
x-increment = 1 ; y-increment = 1
|
| B. |
x-increment = 0.5; y-increment = 1
|
| C. | x-increment = 1 ; y-increment = 0.5 |
| D. | none of the above |
|
Option: C Explanation :
x - increment = x2 -x1 / max ((x2 -x1), (y2 - y1))
y - increment = y2 -y1 / max ((x2 -x1), (y2 - yl))
