Answer:
PL = 9
PN = 5√5
Step-by-step explanation:
8/12 = 6/PL
8PL = 72
PL = 9
PN² = 10² + 5² = 100 + 25 = 125
PN = √125 = 5√5
The answer, at least what I got, is 17.375 . They'd have to open an eighteenth package because the extra .375 is not in the original package, so I would go with B .
(-3)/(-5) makes 3/5 because the (-) cancels out
Derivating the equation:

So the slope of the tangent in the point (0,1) is:

Then, the slope of the normal (n) line in the point (0,1) is:
Step-by-step explanation:
a (-infinite , -3) U (3 , infinite)
b + 5 , - 5
