Answer: Black
Step-by-step explanation: I feel like the higher the line is on the graph, the farther they have moved, so since the black line is the lowest, it might be Noah.
Hope this helps!
Answer:
20
Step-by-step explanation:
Charle would have spent that much because one pound is 2.50
15 divided by 6=2.50
2.50x8=20
The red vector has a magnitude of 22 and makes an angle of 39 degrees with the horizonal x-axis.
Converting to rectangular form: x = 22 cos 39 deg and y = 22 sin 39 deg
So, this question is basically asking us "If we had an x instead of a 2, would this be true?" We can try and see what we get:

So, if we want to show this we have to change the numerator or denominator in such a way that we can cancel some common factors. Notice that 
If we replace the factored numerator with the original one, we get:

Since we have an equality, this relation is proved.
Answer:
5 seconds
Step-by-step explanation:
<em>First let's use the equation.</em>
D (Distance) = Speed (s) x Time (t)
<em>Now let's find the components given in the problem.</em>
Distance = 10 meters
Speed = 2 m/s
<em>Now let's substitute the values in.</em>
10 = 2t
<em>Now let's solve for t.</em>
10 = 2t
t = 
t = 5
Therefore, it will take 5 seconds.
