Answer:
6 inches
Step-by-step explanation:
just divide both 12 and 8 by 2 since 4 is half of 8.
First person = 10 min
Second person = 15 min
Time together = x
Equation Formation
x = (10+15) ÷2
x = 12.5
Answer = 12.5 minutes
Amount of Job done by the slowest person.

We will use the product rule:
d/dx( f(x) · g(x) ) = f´( x ) g( x ) + g´( x ) f( x ) ( and after that the chain rule )
y´ = ( x ) ´· e^(-x/2) + ( e^(-x/2)´ · x) =
=
