Take North to be positive and South to be negative. Then
8 m/s = -8 m/s + <em>a</em> (4 s)
which is the formula for velocity <em>v</em> given initial speed <em>u</em>, acceleration <em>a</em>, and time <em>t</em>,
<em>v</em> = <em>u</em> + <em>a t</em>
Solve for <em>a</em> :
16 m/s = <em>a</em> (4 s)
<em>a</em> = (16 m/s) / (4 s)
<em>a</em> = 4 m/s²
(since it's positive, the acceleration is in the Northern direction)
The first one is 24
the second one is 16

Answer:
360 for first place and 240 for second
Step-by-step explanation:
Let's say f is the first place prize, and s is the second prize.
Amaal: 4f + 2s = 1920
Brian: f + 3s = 1080
Now we can isolate and substitute.
f = 1080 - 3s
4(1080 - 3s) + 2s = 1920
4320 - 12s + 2s = 1920
10s = 4320 - 1920
10s = 2400
s = 240
f = 1080 - 3*240
= 1080 - 720
= 360

Answer:
6
Step-by-step explanation:
The slope of the line between (3, 3) and (4, 9) is given by the slope formula:
m = <average rate of change> = (y2 -y1)/(x2 -x1)
m = (9 -3)/(4 -3) = 6/1
m = 6
The average rate of change on the interval [3, 4] is 6.
