11/12

Step-by-step explanation:

You have to add the fractions. To do this, you need common denominators.

To get 5/6 to have a denominator of 12, multiply 6 by 2. You do this because 6x2 is 12If you do something to the denominator, you have to do it to the numerator as well. So do 5x2 to get 10Your new fraction is 10/1210/12+1/12 is 11/12

$(\frac{5}{\sqrt{34}} ,\frac{-3}{\sqrt{34}} )$

Step-by-step explanation:

The vector v:

(2,4)-(-3,7)

=(5,-3)

norm:

||(5,-3)||= $(5^2+3^2)^{ 1/2}=\sqrt{34}$

unit vector:

$(\frac{5}{\sqrt{34}} ,\frac{-3}{\sqrt{34}} )$
