$0.42 that is what your answer would be
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: 
<u>Step-by-step explanation:</u>
From the data provided, we know the sequence is {500,000; 550,000; 605,000; ... }. 
The explicit rule for a geometric sequence is: 
So, the explicit rule for the sequence above is:
