Functions can be represented using equations, graphs and tables.
The function is given as:
![a(l) = \frac 12 l^2](https://tex.z-dn.net/?f=a%28l%29%20%3D%20%5Cfrac%2012%20l%5E2)
When l = 1, we have:
![a(1) = \frac 12 \times 1^2](https://tex.z-dn.net/?f=a%281%29%20%3D%20%5Cfrac%2012%20%5Ctimes%201%5E2)
![a(1) = 0.5](https://tex.z-dn.net/?f=a%281%29%20%3D%200.5)
When l = 2, we have:
![a(2) = \frac 12 \times 2^2](https://tex.z-dn.net/?f=a%282%29%20%3D%20%5Cfrac%2012%20%5Ctimes%202%5E2)
![a(2) = 2.0](https://tex.z-dn.net/?f=a%282%29%20%3D%202.0)
When l = 3, we have:
![a(3) = \frac 12 \times 3^2](https://tex.z-dn.net/?f=a%283%29%20%3D%20%5Cfrac%2012%20%5Ctimes%203%5E2)
![a(3) = 4.5](https://tex.z-dn.net/?f=a%283%29%20%3D%204.5)
When l = 4, we have:
![a(4) = \frac 12 \times 4^2](https://tex.z-dn.net/?f=a%284%29%20%3D%20%5Cfrac%2012%20%5Ctimes%204%5E2)
![a(4) = 8.0](https://tex.z-dn.net/?f=a%284%29%20%3D%208.0)
Represent the above results as a table, we have:
<u>l a(l)</u>
1 0.5
2 2.0
3 4.5
4 8.0

Answer:
last option
Step-by-step explanation:
To prove that ΔEFG is also a right triangle, you must prove that KL = EF so that in ΔKLM c² = a² + b² which would make ΔEFG a right triangle.
Answer:
20 watches were made.
Step-by-step explanation:
385=15n+85
300=15n
20=n
If you were to list these numbers in order from greatest to least, it would be 1.29, 1.202, 1.02.
Hope this helps!!
Answer:
A) from the line of best fit, the approximately y-intercept is (0,1.8). This means without any practice, 1h.8 games are won.
B) slope: (5.6-1.8)/(2-0) = 1.9
y = 1.9x + 1.8
(Line of best fit)
x = 13,
y = 1.9(13) + 1.8 = 26.5
Predicted no. of games won after 13 months of practice is 26.5
