Answer:
1)
2)
3)
Step-by-step explanation:
Given : A certain economy's consumption function is given by the equation
where, C(x) is the personal consumption expenditure in billions of dollars, and x is the disposable personal income in billions of dollars.
To find :
1) C(0)
Put x=0 in the given equation,
2) C(50)
Put x=50 in the given equation,
3) C(100)
Put x=100 in the given equation,
Option B: is sufficient to prove that
ll
Explanation:
Given that ACD is a triangle.
The line EB intersects the sides AC and AD of the triangle.
The point E intersect the side AD and B intersect the side AC.
We need to prove that ll
Then, the side splitter theorem states that "If a line intersects two sides of a triangle and divides the sides proportionally, the line is parallel to the third side of the triangle".
From the side splitter theorem, the line EB intersects the two sides of the triangle AC and AD and divides the sides proportionally.
Thus, the proportion of the sides is given by
This proportionality shows that the line is parallel to the third side of the triangle.
Hence, is sufficient to prove that
ll
Therefore, Option B is the correct answer.
