Since the shark is in a deep water level of specifically 80 feet it is then represented by a negative coefficient. This is due to the vector quantity the measure represents as decelerating or sinking or downward in direction. As oppose the shark moves upward with a height of 15ft.
Thus the expression will be -80ft + 15 ft = -65ft is the displacement.
15ft is positive since the movement is upward and the displacement then from the origin to the point of last position is 65ft, negative.
Answer:
a. 
Step-by-step explanation:
The given vector is v= 4i - 5j
The magnitude of this vector is;
The unit vector u in the direction of v is;
We rationalize to get
Combine like terms. So that means combine the X's and combine the regular numbers.
- add 2x to 8x
- combine +15 -5
- then add 11 to that
- once you're done, find X by dividing 10x by whatever you have after the = sign
