Step-by-step explanation:
f(x) = y= -x²-x+6
When y is max, f'(x) = 0
f'(x) = -2x-1
Equating to 0,
-2x-1= 0
x= -1/2
Put the value of x in f(x)
y = -(-1/2)² -(-1/2) +6
= -1/4+1/2+6
= 6+1/2
y= 13/2
Answer:
1/5 gallon per minute
Step-by-step explanation:
The fill rate for container 1 is 2 gallons in 10 minutes. For container 2 it is 4 gallons in 10 minutes. The difference in rates is ...
(4 gal - 2 gal)/(10 min) = 2/10 gal/min = 1/5 gal/min
