Dot product is 
a*b = |a|*|b|*cosα.
In our case
u*u =|u|*|u|*cos 0
u*u =|u|*|u|
12=|u|²
|u|=√12=√(4*3)=2√3

6x=7-4y
Move 'y' to one side
6x-7=-4y
6x-7
------- = y

Answer:
Step-by-step explanation:
Area of a Semi Circle
Area = 1/2 pi r^2
r = d/2
r = 3/2
r = 1.5
Area = 1/2 3.14 * 1.5^2
Area = 1/2 * 3.14 * 2.25
Area =                                                           3.5325
Area of Rectangle
L = 12 Yd
W = 4 Yd
Area = L * W
Area = 12 * 4<u>  =                                          48 </u>
Total Area =                                               51.5325
 
        
             
        
        
        
First you multiply 145 by 01.75 to get how much you add to the total. You add 253.75 to 145 and get 398.75 as the answer
