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))
Answer:
To calculate the cylinder's volume we can use the formula to calculate this. We get pretty good number which gives us 75.4 Here's how I calculated it.
Answer: 75.4

Let Sister's age now = s
So Larry is now s + 8
In THREE Years Sister = s + 3
Larry = {s + 8} + 3
But We are told that he will be TWICE as old as Sister is NOW!!!
So s + 11 = {2s}
Solve s = 11
So Sister is ELEVEN Years old and Larry is NINETEEN Years old.
So times $64.80 by 2.5. You minus 20 from that, so that the RacerZ is $142. You take that $142 and times that by 1.09. You get 154.78. Therefore;
Speedmonster- 64.80
RacerZ- 142
Swiftee-154.78
Hope this helps. :)
