The given equation is -3x²+240x-800
The maximum of the function is given when
where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have
Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
Answer:
-25
Step-by-step explanation:
The answer is correct
I believe the answer is D: 6×9÷3.
The question is a word problem, and they are asking you to put it into a numerical problem, meaning with numbers. 6 times 9 divided by 3 put into a numerical equation is 6×9÷3.
