A market economy is an economic system in which economic decisions and the pricing of goods and services are guided solely by the aggregate interactions of a country's individual citizens and businesses. There is little government intervention or central planning.
Answer: Sin N = 
Step-by-step explanation:
Since we have given that
In triangle MPN, ∠P=90°
As we know the formula for "Trigonometric Ratios":
By Pythagorus theorem , we get
So, we get,
Hence, Sin N =
13 is not the same as 1/3! The division symbol is not a symbol used to connect two numbers, it is used to find their quotient. For example, 6/2 would be like saying: You have 6 cookies, and 2 friends. How many cookies does each friend get? The answer is obviously not 62, it is 3! So, the exact quotient is 0.3 repeating. You could memorize this or use the fact that 0.9 repeating is 1.
1: (pi)5^2 = 78.54 then multiply that by 11 and you get 863.94
2: (pi)13^2= 530.93 then multiply that by 8 and you get 47247.44
3. (pi)18^2= 1017.88 then multiply that by 22 and you get 22393.36
Try using an app called Symbolab it helps a lot !
