Vectors a = (3, 4) and b = (m, 2) are given. For which value of m they are perpendicular?

The value of m is .

Step-by-step explanation:

If two vectors and are perpendicular to each other then their dot product will be zero i.e

If two vectors and are parallel to each other then their cross product will be zero i.e

Given vectors are a= (3,4) and b=(m,2)

The position vector of  is =

The position vector of  is =

Since and are perpendicular.

Then,

⇒3.m +4.2=0

⇒3m+8=0

⇒3m= -8

The value of m is .

tangent

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
