Profit, P(x), is the difference between revenue, R(x), and cost, C(x), so P(x) = R(x) - CC). Which
aleksklad [387]

Answer:

Step-by-step explanation:

Profit, P(x), is the difference between revenue, R(x), and cost, C(x)

R(x) = 2x^4 - 3x^3 + 2x - 1

C(x) = x^4 -x^2 + 2x + 3

Substituting into the equation

P(x) = R(x) - C(x)

= (2x^4 - 3x^3 + 2x - 1) - (x^4 -x^2 + 2x + 3)

= x^4 - 3x^3 + x^2 - 4

The answer is the lower left option.

PLSS HELP ASAP
Mama L [17]

based on the number of marbles in the bag, the number of marble groups possible is 7,140 groups.

the probability of selecting 2 red and 1 yellow is 1/68.

<h3>what number of 3-marble groups can be made?</h3>

first, find the number of marbles:

= 7 + 8 + 9 + 7 + 5

= 36

the number of marble groups are:

= 36 ! / (3 ! x 33 !)

= 7,140 groups

the probability of picking 2 red and 1 yellow is:

= (( (7! / (2! x 5!)) x ( ( 5! / (1! x 4!))) / 7,140

= 1 / 68

= 1.47%

HELP PLZ DUE RN BRAINIEST TO WHOEVER RIGHT
Y_Kistochka [10]

Answer:

x = \dfrac{2}{5} + \dfrac{\sqrt{14}}{5}   or   x = \dfrac{2}{5} - \dfrac{\sqrt{14}}{5}

Step-by-step explanation:

5x^2 - 2 = 4x

5x^2 - 4x - 2 = 0

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

x = \dfrac{-(-4) \pm \sqrt{(-4)^2 - 4(5)(-2)}}{2(5)}

x = \dfrac{4 \pm \sqrt{16 + 40}}{10}

x = \dfrac{4 \pm 2\sqrt{14}}{10}

x = \dfrac{2 \pm \sqrt{14}}{5}

x = \dfrac{2}{5} + \dfrac{\sqrt{14}}{5}   or   x = \dfrac{2}{5} - \dfrac{\sqrt{14}}{5}
