Answer:
-1.
Step-by-step explanation:
First find the derivative of f(x):
f'(x) = -3x^2 + 12x - 9 = 0 for a maximum or minimum.
-3(x^2 - 4x + 3) = 0
(x - 1)(x - 3) = 0
x = 1, 3.
To find which gives a relative maximum we find the second derivative:
f"(x) = -6x + 12
When x = 1 f"(x) = 6, positive.
when x = 3, f"(x) = -6, negative.
So x = 3 gives a maximum value of f(x).
f(3) = -(3)^3 + 6*(3)^2 - 9(3) - 1 = -1 (answer).
13/24, 7/12, 5/8, 2/3, 5/6 :)

The correct answer is $614
Explanation:
To calculate the total amount Kiki earned during the three days, it is necessary to find out first the money she earned on commissions ( 8% of each item she sold) and then add this to the total of her base salary ($150 per day). To begin, you can find the 8% of any price by dividing the total price by 100 and then multiplying it by 8, considering the total price represents 100% and by dividing by 100 you will get the value of 1%, then if you multiply this by 8 you will know the 8%.
$350 /100 = 3.5 x 8 = $28 (commission of the sofa chair)
$500/100 = 5 x 8 = $40 (commission of the loveseat)
$1,200/ 100 = 12 x 8 = $96 (commission of the couch)
This means, Kiki earned a total of $164 in commissions (28 + 40 + 96 = 164), and if you add this to the total of her base salary (150 + 150 + 150 =450) during the three days, the total earned is $614 because $ 450 (base salary) + $164 (commissions) equals $614.
1 1/2 because it is the answer of 4 - 1 1/2
