Step-by-step explanation:
the sum of the angles = 360
8x+2 + 2x + 14 + 3x -4 +5x + 5 = 360
18x +17 = 360
18x = 343
x = 19.1
angles are:
154.8
52.2 smallest (2x + 14)
53.3
105.5
f(x) = 12 when x=2
Step-by-step explanation:
Given that
f(x) is inversely proportional to x
This is mathematical written as
f(x) ∝1/x
It can be written as:
![f(x) = \frac{k}{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7Bk%7D%7Bx%7D)
where k is the proportionality constant
So,
![8 = \frac{k}{3}\\8 * 3 = k\\k = 24](https://tex.z-dn.net/?f=8%20%3D%20%5Cfrac%7Bk%7D%7B3%7D%5C%5C8%20%2A%203%20%3D%20k%5C%5Ck%20%3D%2024)
Now the equation will be:
![f(x) = \frac{24}{x}\\Putting\ x=2\\f(x) = \frac{24}{2}\\f(x) = 12](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B24%7D%7Bx%7D%5C%5CPutting%5C%20x%3D2%5C%5Cf%28x%29%20%3D%20%5Cfrac%7B24%7D%7B2%7D%5C%5Cf%28x%29%20%3D%2012)
Hence,
f(x) = 12 when x=2

#2 the answer you chose is right
Step-by-step explanation:
Answer:
$888
Step-by-step explanation:
I=P×T×R/100
=600×8.25×0.5/100 [8 year 3 months=99 months = 8.25 year ]
=1237.5/100
I =12.375
A= I +P
=600+12.375
A =612.375
hence the total amount will be $ 612.375
