By Simposon's rule taking n = 4, the value of the integral is equal to
0.785
0.788
0.781
None of these
The foot of perpendicular from the point (3, 4, 5) to the plane x + y + z = 9 is
(2, 3, 4)
(3, 5, - 2)
(3, 5, 2)
(3, 2, 4)
A.
(2, 3, 4)
Let M be the foot of perpendicular from P(3, 4, 5) to the given plane, then PM is normal to the plane. So, its DR's are (1, 1, 1).
Put k = - 1 in Eq. (i), we get The coordinate of M(-1 + 3, - 1+ 4, - 1 + 5) i.e M(2, 3, 4).
