Answer: p=8
Step-by-step explanation:
4p-11=21
We move all terms to the left:
4p-11-(21)=0
We add all the numbers together, and all the variables
4p-32=0
We move all terms containing p to the left, all other terms to the right
4p=32
p=32/4
p=8
Answer:
None of these statements are true.
Step-by-step explanation:
a) The derivative of (fg)(x) is f'g +fg' according to the product rule for derivatives.
__
b) The derivative of |x² +x| is a 3-part piecewise linear function equal to 2x+1 for |x+1/2| > 1/2, and equal to -2x-1 for |x+1/2| < 1/2. It is undefined for x=0 and x=1.
__
c) for y = √f(x), y' = f'(x)/(2√f(x))
