Answer:
f'(x) = (-6x² -14x -23)/(x² +5x +2)²
f''(x) = (12x³ +42x² +138x +202)/(x² +5x +2)³
Step-by-step explanation:
The applicable derivative formula is ...
d(u/v) = (v·du -u·dv)/v²
__
f'(x) = ((-x² -5x -2)(4x +4) -(2x² +4x -3)(-2x -5))/(-x² -5x -2)²
f'(x) = (-4x³ -24x²-28x -8 +4x³ +18x² +14x -15)/(x² +5x +2)²
f'(x) = (-6x² -14x -23)/(x² +5x +2)²
__
Similarly, the second derivative is the derivative of f'(x).
f''(x) = ((x² +5x +2)²(-12x -14) -(-6x² -14x -23)(2(x² +5x +2)(2x +5)))/(x² +5x +2)⁴
f''(x) = ((x² +5x +2)(-12x -14) +2(6x² +14x +23)(2x +5))/(x² +5x +2)³
f''(x) = (12x³ +42x² +138x +202)/(x² +5x +2)³
Step-by-step explanation:
to solve you just add the length of each line segment. In this problem 1.7+3.2=4.9
Answer:
C.
Ax + 1 = x A + 1
Bx + 2 = x B + 2
Cx + 3 = x C + 3
A = x C + 3
B = x C + 3
C = x C + 3

Step-by-step explanation:
The first step is to find out what times 9 - 23 = 49 the first step would be to add 49 + 23 and that would get 72 so then you find that x would = 8 so the second step should be to put the problem together so 72 - 23 = 49. so basically x would equal 8.
