If a=2hat(i)-3hat(j)+5hat(j)," " b=3hat(i)-4hat(j)+5hat(k)andc=5hat(i)-3hat(j)-2hat(k) , then the volume of the parallelpiped with contermiouns edges a+b, b+c, c+a, is

If (2)/(3)j-(1)/(4)k=(5)/(2) , what is the value of 8j-3k ?

vec a=2hat i-hat j+hat k,vec b=hat i+2hat j-hat k,vec c=hat i+hat j-2hat k A vector coplanar coplanar with vec b and vec c whose projectin on vec a is magnitude sqrt((2)/(3)) is hat i+3hat j-3hat k b.-2hat i-hat j+5hat k c.2hat i+3hat j+3hat k d.2hat i+hat j+5hat k

If a = 3i - j - 2k, b = 2i + 3j + k then (a + 2b) xx (2a - b) =

If A(3i-2j-k), B(2i+3j-4k), C(-i+j+2k)" and "D(4i+5j+lambdak) are coplanar points, then lambda= ________

If a and b are vectors such that |a+b|=sqrt(29) and a xx(2i+3j+4k)=(2i+3j+4k)xx b, then a possivalue of (a+b)*(-7i+2j+3k) is

If vec(a)= hat(i) - 2hat(j) + 5hat(k), vec(b)= 2hat(i) +hat(j)- 3hat(k) then what is (vec(a)- vec(b)).(3 vec(a) +vec(b)) equal to ?
