Answer:
(b) 30
Step-by-step explanation:
The standard form of a quadratic is ...
y = ax^2 +bx +c
For such a function, the axis of symmetry is ...
x = -b/(2a)
Your quadratic function has a=-5, b=+300, so the axis of symmetry is ...
x = -300/(2(-5) = 30
The peak of the curve is on the axis of symmetry. So, profit is maximized when 30 items are produced.
_____
Of course, a graphing calculator can display the maximum of the function easily.
Each coin has 2 possible outcomes, head or tails.
Therefore 4 coins has total of 8.
Each dies has 6 possible outcomes, so rolling 2 times has
a total of 12.
There are 52 possible cards, if 4 are drawn without
replacement so the total possible is 52*51*50*49.
We multiply all numbers:
8*12*52*51*50*49 = 623,750,400

0.03 = 3/100
558 = 558/1
3/100 ÷ 558/1 = 3/100 X 1/558 = 1/100 X 1/186 (÷3)
1/100 X 1/186 = 1/18600 (0.0000537634/5.537634 X 10 to the power of 5)
The answer to this question is x = 13/9 = 1.444
Answer:
D. 2x^2-7x.
Step-by-step explanation:
Lets write it out to make it easy to work with.
-x(-2x+7)
Multiply the -x out
2x^2-7x.
The answer is D
