lines are perpendicular find combined eqn 3x2-4xy=0
Hello dear,
Given equation is 3x^2-4xy=0
x(3x-4y) =0
separate equations of the lines are x = 0 and 3x-4y =0
let m1 and m2 be the slopes of these lines
then m1 does not exist and m2 =3/4
now, required lines are perpendicular to these lines
their slopes are -1/m1 and -1/m2
since m1 does not exist -1/m1 =0
also , m2 = 3/4 , -1/m2 =-4/3
Their combined equation is 4xy +3y^2 =0
what is the order of the product of a pair of disjoint cycles of length 4 and 6? (Algebra question)
Order = 1cm (length of cycles in disjoint pair)
= 1 cm (4,6)
Order = 12
If Rank of A is 2 and Rank of B is 3 then the Rank of AB is ?
Hello there!
Greetings!
To solve these kind of questions you should always remember that if A and B are matrices then rank of AB is always less than or equal to rank of matrix A . And if the matrix B is a non -singular matrix then rank of AB is equal to A . So in case if B is a non -singular matrix then rank of (AB)= rank(A)=2 (given).
Thankyou
