A scientist plots a vector on a coordinate grid to record the movement of a migrating whale. The units of the coordinate grid are kilometers, and the positive y -axis on the coordinate grid points north. The vector has initial point (0,0) and terminal point (5,12) . What are the approximate distance and direction of the whale’s movement? A 13 kilometers, 65° north of east B 17 kilometers, 67° north of east C 13 kilometers, 67° north of east D 17 kilometers, 65° north of east

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
