If F(x) = f(x)g(x), where f and g have derivatives of all orders

user100 [1]

a. By the product rule,

$F=fg\implies F'=f'g+fg'$

$\implies F''=(f''g+f'g')+(f'g'+fg'')=f''g+2f'g'+fg''$

b. By the same rule,

$F'''=(f'''g+f''g')+2(f''g'+f'g'')+(f'g''+fg''')$

$F'''=f'''g+3f''g'+3f'g''+fg'''$

and

$F^{(4)}=(f^{(4)}g+f'''g')+3(f'''g'+f''g'')+3(f''g''+f'g''')+(f'g'''+fg^{(4)})$

$F^{(4)}=f^{(4)}g+4f'''g'+6f''g''+4f'g'''+fg^{(4)}$

c. You might recognize the coefficients as those that appear in the expansion of $(a+b)^n$ :

1, 1

1, 2, 1

1, 3, 3, 1

1, 4, 6, 4, 1

and so on; the general pattern (known as the general Leibniz rule) is

$F^{(n)}=\displaystyle\sum_{k=0}^n\binom nkf^{(n-k)}g^{(k)}$

Solve for h. -3(3h – 1) ≤ -7h – 5

bezimeni [28]

-3(3h-1)≤-7h-5
-9h+3≤-7h-5
-9h+7h≤-5-3
-2h≤-8
h≥4
Sign changes because you multiply with negative both sides.

Which of the following is an example of an ordered pair: * M

prisoha [69]

Answer: B

Step-by-step explanation:

An ordered pair is another way of saying “point” or “coordinate”. Knowing that, we know A and C are expression and equation, respectively. We are left with B and D. We know that B is the correct answer because that is the proper way to write an ordered pair, or coordinate. Therefore, B is the answer.
