Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x
BD ≈ 5.36

Where,
We have, replacing,
We need to derivate and verify for stable equilibrum that,
Then,
Roots in,
We obtain U"(x), then we have
For Unestable
For Stable
Answer:
B
Step-by-step explanation:
It's domain is side from side and so it can't be c or d. and it range goes to a positive number so it has to be B.
