Answer:
c. 2; no
Step-by-step explanation:
The inner product is the sum of the products of corresponding vector components. It is a scalar value, not a vector value.
(3, 5)·(4, -2) = (3)(4) +(5)(-2) = 12 -10 = 2
When the inner product is non-zero, the vectors are not perpendicular. (The yes answers with a non-zero value can be rejected out of hand.)
The appropriate choice is ...
2; no
$12.64
A multiplicative inverse or reciprocal for a number x, is denoted by 1/x or x‾¹.
So, the answer to your question is <u>B. a × (1/a) = 1. </u>
Hope this helps!! :)
