Expert Solution

Step 1: INTRODUCTION

Given Data :

vector $A with rightwards arrow on top equals negative i with hat on top minus 4 j with hat on top$

vector $B with rightwards arrow on top equals negative 3 i with hat on top minus 2 j with hat on top$

Vector dot product formula is given by

$A with rightwards arrow on top. B with rightwards arrow on top equals open vertical bar A close vertical bar open vertical bar B close vertical bar cos theta..... left parenthesis 1 right parenthesis$

Where,

$theta$ is the angle between them
