Which graph represents the function? f(x)=5√x

1 answer:

Serggg [28]3 years ago

3 0

Step-by-step explanation:

Since the x is inside of the square root, the x value must be positive. This makes x {0,infinity). Yet, when square rooting x, you should have both a negative and a positive value for y. So, this should be your graph.

The total profit Upper P (x )(in thousands of dollars) from the sale of x hundred thousand pillows is approximated by Upper P

leva [86]

Answer:

10 hundred thousands of pillows must be sold to maximize the profit of 900 thousands dollars.

Step-by-step explanation:

We are given the following in the question:

$P(x) = -x^3 + 9x^2 + 120x - 200\\x\geq 5$

Where P(x) is the profit in thousand of dollars and x is the hundred thousand pillows sold.

First, we differentiate P(x) with respect to x, to get,

$\dfrac{d(P(x))}{dx} = \dfrac{d(-x^3 + 9x^2 + 120x - 200)}{dx} = -3x^2 + 18x+120$

Equating the first derivative to zero, we get,

$\dfrac{d(P(x))}{dx} = 0\\\\-3x^2 + 18x+120 = 0$

Solving, with the help of quadratic formula, we get,

$x =-4, x = 10$

Again differentiation P(x), with respect to x, we get,

$\dfrac{d^2(P(x))}{dx^2} = -6x + 18$

At x = 10

$\dfrac{d^2(P(x))}{dx^2} < 0$

Thus,by double differentiation test maxima occurs at x = 10 for P(x).

Thus, 10 hundred thousands of pillows that must be sold to maximize profit.

Maximum Profit

$P(10) = -(10)^3 + 9(10)^2 + 120(10) - 200 = 900$

Thus, the maximum profit is 900 thousands of dollars.

There are two cookie jars: jar 1 contains two chocolate chip cookies and three plain cookies, and jar 2 contains one chocolate c

vesna_86 [32]

Answer:

P = 0.55 or 55 %

Step-by-step explanation:

First step: Fred has probability of 0,5 when chossing jar 1 or jar 2

Second step : The probability of chossing one chocolate chp cookie in jar 1 is 3/5 and from the jar 2 is 1/2

Then the probability of Fred to get a chocolate chip cookie is

P ( get a chocolate chip cookie ) =( 0.5 * 3/5) +( 0.5* 1/2)

P = 0.3 + 0.25

P = 0.55 or 55 %
