Answer= c
In this case you've got to place the vector from the origin, so you have to get the difference from both points (x2-x1) and (y2-y1)
So you get that the vector from the origin is (18,-7)
Know you know the vector v is three times the vector u, so you multiply three times the vertex, but remember the vector v goes int he opposite direction, so the vector v from origin the the terminal point is (-54, 21)

Hi there!
Your question is:
For 8 days of very hot weather, the water level in a lake dropped 3 inches per day. on the ninth day, storms raised the level 6 inches. Write and find the value of an expression for the change in the water level of the lake during these 9 days.Here is my answer:
If the water level drops 3 inches per day for eight days, it would have gone down a total of 24 inches over those 8 days. Now, the rain storm added 9 inches of water back to the lake. 24 - 9 = 15.
Summary:
8 x 3 = 24
-24 + 9 = -15.
I hope this helped you, and dont hesitate to ask me for anymore help if you need it.
Stay Crazzzzzy! xD

Answer:
Step-by-step explanation:
<u>Given Data:</u>
Speed = v = 855 m/s
Distance = S = 2 km = 2000 m
<u>Required:</u>
Time = t = ?
<u>Formula:</u>
v = S/t
<u>Solution:</u>
Rearrange the formula
t = S/v
t = 2000/855
t = 2.34 seconds
Hope this helped!
