Precal: find the inner product for (8,4) (2,4) and state whether the vectors are perpendicular. a. 8; no c. 32; no b. 8; yes d. 32; yes

Alright, let gets started.

First vector : <8, 4>

Second vector : <2, 4>

Inner product is the another name of dot product.

Means we need to find dot product of these two vectors.

So, dot procuct of <8, 4> and <2, 4> = 8*2 + 4*4

dot product = 16 + 16 = 32

Hence inner or dot product of <8,4> & <2, 4> is 32. Answer

If the dot product of two vectors are zero then both vecotrs are said to be perpenducular else not.

Here in our question, dot product is 32 which is not equal to zero, which means our given vectors are not perpendicular.

Hence answer is 32, NO : Answer
