Y=1/2x-2
Since y is 2 less than half of x, you subtract to from 1/2x to equal y.
Answer:
a)the largest Herfindahl index possible = 200
b)the four firm concentration ratio = 8%
Step-by-step explanation:
a) from the question, it follows that the largest share any dealer can have is 2% and the sum of all dealer shares must equal 100% of the market.
We therefore have a maximum number of firms to be 100%/2% = 50.
Since we now know that the maximum number of firms is 50,thus;
At a maximum concentration share of 2% for all firms, the largest Herfindahl index possible = number of firms x percentage squared for each firm = 50 x (2)² = 200
b) In the same logic above, the four firm concentration ratio = 4 x share of the market = 4 x 2% = 8%
Answer:
#2:
To get rid of a radical we multiply the radical by itself, so we multiply 
to get 
.
#3:
is the same as 
so we multiply by 
so we get 
.
#4:
We combine like terms to get 
Hope this helps!
The answer is B- the other one would be 25y=x
Answer:
about 65°
Step-by-step explanation:
Using the tangent ratio in the right triangle
let x be the angle of elevation ( measured up from the horizontal )
tanx = 
= 
, thus
x = 
( ) ≈ 65°
