Use dot product
a=(x1,y1) and b=(x2,y2)
a.b=/a/*/b/ cos x
a.b mean dot product of two vectors
a.b is equals x1*y1+x2*y2
Answer: Divide the total displacement by the total time.
In order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity. Example 1 (cont.): The car changed its position by 36 meters over 8 seconds.
Answer:
A
Step-by-step explanation:
To sovle this we must combine the numbers togther and the variables togther.
We have:
8c+6-3c-2
Lets take out the c's and combine them:
8c -3c
=
5c
Now lets take out the numbers:
6-2
=
4
Now lets put these back together and we get the expression:
5c+4
This looks like A.
Hope this helps! :D
