Hi there! Let’s see if I can help you <3
The Answer is: 15.81!
Here’s the step by step explication:
First we must find the difference of U and V: (7i-12j)-(-2i+j)
Distributed all out will equal: 9i-13j
We can then go ahead and use Pythagorean therm to find the magnitude: V = Square root of (9)^2 + (-13)^2
This equals Square root of 250!
Depending on the form your teacher wants to answer in it would finally be 5 square roots of 10 or in decimal form; approximately 15.8114!
HOPE IT HELPED YOUUU <3
