To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0.
C(x) = 400x - 0.2x²
dC(x) / dt = 400 - 0.4 x = 0
The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation,
C(x) = (400)(1000) - 0.2(1000²) = $ 200,000
Thus, the answer is letter B.
1. B and D
2.A
I hope this helped, woof.
None of the answer choices makes any sense. (You should have your teacher show you how to select the correct choice.)

Answers that are closer to the plotted points are ...
... A = -0.9, B = -9/16, C = -0.4, D = -1/16
The attachment shows these points plotted. As you can see, even these values aren't quite right.
Answer/Step-by-step explanation:
7m + 11 = -4(2m + 3)
<u>Use distributive property:</u>
7m + 11 = -8m - 12
<em>Therefore the equations are equivilent!</em>

First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer.
To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)
8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120.
120/4=30
It takes 30 minutes to fill the pool up to 120 gallons.
