First we have to find derivative of f(x):
For x=2 we have:
Now,
Hence, the answer is A) 2
Given that segment FE is parallel to segment DG, which of the following statements is NOT true?
2 answers:
Answer: The correct option is
(B) triangle HFE is congruent to triangle HGD.
Step-by-step explanation: Given that the segment FE is parallel to segment DG in the figure.
We are to select the statement that is NOT true.
From the figure, we note that FE is parallel to DG and FG is a transversal, so we have
m∠HFE = m∠HGD
Again, FE is parallel to DG and ED is a transversal, so we have
m∠HEF = m∠HDG
Also, m∠EHF = m∠DHG [vertically opposite angles]
Therefore, ΔHFE is similar to ΔHGD by AAA similarity postulate.
We know that the corresponding sides of two similar triangles are proportional, so we get
Thus, options (A), (C) and (D) are TRUE.
Only option (B) is NOT TRUE.
Option (B) is CORRECT.

Cathy and Iris have 259,459,200 ways to skip countries.
Data;
- Number of countries they are planning to visit = 9
- Number of countries they would like to visit = 13
To solve this problem, we would have to use a mathematical procedure known as combination.
Let us calculate the number of countries that would have to skip.
To decide which country they have to skip, it would be 4 out of 13.
Let's solve this
