A polynomial of degree n can pass through n + 1 points. So, if we have n + 1 points, we can construct a unique polynomial that passes through all those points.

A nonzero polynomial passing through a specific point (x, y) means that the value of the polynomial at that x-coordinate must be equal to the y-coordinate of the point. So, if the point (2, 0) is one of the points that the polynomial passes through, then we have:

[tex]p(2) = 0[/tex]

We can construct a polynomial with this information. For example, one possible polynomial is:

[tex]p(x) = (x - 2)^2[/tex]

This polynomial satisfies the equation p(2) = 0 since:

[tex]p(2) = (2 - 2)^2 = 0^2 = 0[/tex]

Therefore, the polynomial [tex]p(x) = (x - 2)^2[/tex] is a nonzero polynomial that passes through the point (2, 0) and satisfies the equation p(x). Note that there could be other polynomials that also satisfy the given conditions.

In general, a polynomial of degree n can pass through n + 1 points. So, if we have n + 1 points, we can construct a unique polynomial that passes through all those points.

Find A Nonzero Polynomial P([tex]x[/tex]) Passing Through The Point (2,0) And Satisfying The Equation P([tex]x[/tex]) = P'([tex]x^2[/tex])?

Answer:

17 years & 9 months

Step-by-step explanation:

annual rate 3.9%

every quarter = 3.9%/4 = 0.98%

compounding every quarter = (1+0.98%)

how long = assuming t quarters

2000 * (1+0.98%) ^t = 4000

solve for t

t= 71

so 71/4 = 17 years & 9 months

Answer: We can use the Pythagorean theorem to find the length of the hypotenuse (c) of the triangle:

c = √(a^2 + b^2) = √(75.4^2 + 41.7^2) = √(5702.76 + 1738.69) = √(7441.45)

c ≈ 86.38 yd

Next, we can use the inverse cosine function (arccos) to find angle A:

A = arccos(a/c) = arccos(75.4/86.38)

A ≈ 30.49°

Finally, we can use the complementary angle formula to find angle B:

B = 90° - A

B ≈ 59.51°

So, the length of the hypotenuse is approximately 86.38 yards, angle A is approximately 30.49 degrees, and angle B is approximately 59.51 degrees.

Step-by-step explanation:

The required demand function and revenue per ticket are p(x) = -0.4 * (x - 21000) + $9 and  $9.

a) To find the demand function p(x), we can use the two data points: (21000, $9) and (26000, $7). To find the slope of the demand function, we can use the formula:

slope = (change in price) / (change in attendance)

Plugging in the two data points, we get:

slope = ($9 - $7) / (26000 - 21000) = -$2 / 5000 = -0.4

To find the y-intercept, we can use either data point and the slope we just found. Let's use the first data point:

p(x) = slope * (x - 21000) + $9

Now we have our demand function:

p(x) = -0.4 * (x - 21000) + $9

b) To maximize revenue, we need to find the price that will result in the maximum number of tickets sold. This is equal to the price that corresponds to the peak of the demand function, or the maximum value of x for which p(x) is decreasing. To find this, we can take the derivative of the demand function and set it equal to zero:

dp/dx = -0.4 = 0

x = 21000

So the maximum revenue is obtained by selling 21000 tickets at the price of $9 each, for a total revenue of $189,000. To maximize revenue, the ticket price should be set at $9.

The mean of the sampling distribution is 120

And the standard deviation of the sampling distribution of the mean using sample size of:

a) n = 16 ⇒ [tex]\sigma_{\bar{x}}[/tex] = 5

b) n = 25 ⇒  [tex]\sigma_{\bar{x}}[/tex] = 4

c) n = 36 ⇒  [tex]\sigma_{\bar{x}}[/tex] = 3.33

d) n = 100 ⇒  [tex]\sigma_{\bar{x}}[/tex] = 2

We know that for a normally distributed population, the sample mean is also normally distributed.

The sample mean is:

[tex]\mu_{x}[/tex] = μ

where μ is the population mean.

Here, the population is normally distributed with μ = 120

So, the mean of the sampling distribution for any sample size would be, [tex]\mu_{x}[/tex] = 120

As we know the formula for the standard deviation of the sample mean is:

[tex]\sigma_{\bar{x}}[/tex] = σ/[tex]\sqrt{n}[/tex]

where,  [tex]\sigma_{\bar{x}}[/tex]  is the Standard deviation of the sample mean

σ is the population standard deviation

n is the Sample size.

Here, σ = 20

Using above formula of the standard deviation of the sample mean,

For sample size n = 100

[tex]\sigma_{\bar{x}}[/tex] = 20/[tex]\sqrt{(100)}[/tex]

[tex]\sigma_{\bar{x}}[/tex] = 20/10

[tex]\sigma_{\bar{x}}[/tex] = 2

For sample sizen = 16

[tex]\sigma_{\bar{x}}[/tex] = 20/[tex]\sqrt{16}[/tex]

[tex]\sigma_{\bar{x}}[/tex] = 20/4

[tex]\sigma_{\bar{x}}[/tex] = 5

The probability that an employee posted to country A at age 30 will survive to age 40 if she remains in that country is 2 x 10⁻⁶³

Probability is a mathematical concept that describes the likelihood of a specific event occurring within a set of possible outcomes

Let's start by defining some terms. The force of mortality, also known as the death rate, is the number of deaths per unit time per unit of population.

The probability of survival is the chance that an individual will live past a certain age. In our case, we want to know the probability of surviving from age 30 to age 40 while living in country A.

To calculate the probability of survival, we will use the formula:

[tex]P(x) = e^{-qx}[/tex]

Where P(x) is the probability of survival at age x and qx is the force of mortality at age x.

First, we will calculate the force of mortality for the first five years after arrival in country A using the equation given in the question:

90x+1 = (6 - 1)9x+1

For x = 30, we have:

90(30) + 1 = (6 - 1)9(30) + 1

2701 = 5 * 891 + 1

2701 = 4445 + 1

2700 = 4445

So, q30 = 4445/30 = 148.5

Next, we will use this value to calculate the probability of survival for the first five years in country A:

[tex]P30 = e^{-q3} = e^{-148.5} = 1.2 \times 10^{-64}[/tex]

Since the force of mortality for those who have lived in country A for at least five years is 50% greater than the US Life Tables, 2002, Females, we can calculate the force of mortality for the next 10 years as follows:

qx = 1.5 x qx from US Life Tables

Using the values from Table 3.11, we have:

q31 = 1.5 x 98,424 = 147,636

q32 = 1.5 x 98,362 = 147,543

q33 = 1.5 x 98,296 = 147,444

q34 = 1.5 x 98,225 = 147,338

q35 = 1.5 x 98,148 = 147,222

q40 = 1.5 x 97,500 = 146,250

Finally, we can use these values to calculate the probability of survival from age 31 to age 40:

[tex]P31 = e^{-q31} = e^{-147,636} = 1.3 \times 10^{-65}\\ \\P32 = e^{-q32} = e^{-147,543} = 1.4 \times 10^{-66}\\\\P33 = e^{-q33} = e^{-147,444} = 1.5 \times 10^{-67}\\\\P34 = e^{-q34} = e^{-147,338} = 1.6 \times 10^{-68}\\\\P35 = e^{-q35} = e^{-147,222} = 1.7 \times 10^{-69}\\\\P40 = e^{-q40} = e^{-146,250} = 2.0 \times 10^{-63)}\\\\[/tex]

The proportion of temperatures between 17.02°C and 25°C is 0.9539

The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

mean = 21.02points and

standard deviation =  points.

Now, using

z= (x-u)/σ

z= 17.02 - 21.02/ 2

z= -2

again, z= (x-u)/σ

z= 25- 21.02 / 2

z= 1.99

So, the proportion is

P(x<108.20)-P(x<104.60)

To ensure the best output and price levels are realized in order to maximize returns, business firms engage in the process of profit maximization. In order to achieve its profit objectives, the company modifies important variables including sale price, production costs, and output levels.

"Profit maximization" emphasizes the location of this critical point, or the optimal output at which your company is most profitable. An educational non-profit organization called Khan Academy states that "a corporation striving to maximize profit will produce the quantity where 'marginal cost' and 'marginal income' are equal to each other."

Let x be the number of ceiling fans

If the price per fan when you sell x fans exists (300 - 2x), then the amount received for selling x fans exists x(300 - 2x)

The cost for producing x fans is (20x + 100).

Profit = x(300 - 2x) - (20x + 100)

y = (1000 + 20x)(300 - 2x)

simplifying the equation, we get

y = 300000 - 2000x + 6000x - 40x²

y = -40x² + 4000x + 300000

simplifying the above equation, we get

Answer: (21, 3)

Step-by-step explanation:

Problem 1

L = length

W = width

P = perimeter of the rectangle

P = 2L+2W

P = 20

2L+2W = 20

L+W = 10 after dividing everything by 2.

L = 10-W

area = length*width

A = L*W

A = (10-W)*W

A = -W^2 + 10W

Let x replace W for a temporary basis.

If we graphed y = -x^2+10x, then we'd see the highest point occurs at (5, 25). This means a width of 5 meters leads to the largest area of 25 square meters.

The length would be L = 10-W = 10-5 = 5 meters as well.

It turns out that a 5 meter by 5 meter square is the best choice when trying to max out this rectangle's area.

Step-by-step explanation:

The length and width of a square are equal to each other

Let x = length of a side of a square

Area of a square = Length × Width

                            = (x inches) × (x inches)

                            = [tex]x^{2}[/tex] [tex]in^{2}[/tex]

The area of the square placemat = 169 [tex]in^{2}[/tex]

∴                                            [tex]x^{2} in^{2}[/tex]  = 169 [tex]in^{2}[/tex]

Taking the square root on both sides of the equation to get rid of the square:

                                             x inches = [tex]\sqrt{169}[/tex] inches

                                            x inches = [tex]\sqrt{169}[/tex] inches

   ([tex]\sqrt{169} =[/tex] ± 13. However, the negative value will be rejected since the length of a side CANNOT be negative)    

        So, x = 13 inches

This means the perimeter of the square = (13 + 13 + 13 + 13) inches

                                                                   = 52 inches

∴ 52 inches of fringe will be needed by Sally

Unit conversion:

                                                   I foot = 12 inches

                                      ∴          y feet = 52 inches

     Cross-multiplication is applied:

                       (y feet)(12 inches) = (52 inches)(1 foot)

Isolating y and making it the subject of the formula:

                                   y feet = [tex]\frac{(52 inches)(1 foot)}{12 inches}[/tex]

Inches in the numerator and denominator will cancel each other out completely:

                                  y feet = [tex]\frac{52}{12}[/tex] feet

Applying long division:

The highest quotient to be multiplied by 12 to give a number, which is closest to 52 but still less than 52. 12×4 = 48. Therefore, the quotient is 4 and the remainder is 4.

∴ 52 inches = 4 feet and 4 inches

a) (p → r) ↔ (q → r)

Now, (p → r)≡ ~p∨r

(q → r)= ~q∨r

So, (p → r) ↔ (q → r)≡ (~p∨r)∧(~q∨r)

Therefore, the logical equivalence for the given statement is (p → r) ↔ (q → r)≡ (~p∨r)∧(~q∨r).

The value x= -2 makes the inequality  true.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

12 > 2x + 4

Now, if we put x= 8 then

= 2x+ 8

= 2(8)+8

= 16+ 8

= 24 > 12

So, x=8 is not true

Now,  if we put x= 4 then

= 2x+ 8

= 2(4)+8

= 8+ 8

= 16 > 12

So, x=4 is not true

Now,  if we put x= 12 then

= 2x+ 8

= 2(12 )+8

= 24 + 8

= 32 > 12

So, x=12 is not true

and,  if we put x= -2 then

= 2x+ 8

= 2(-2)+8

= -4+ 8

= 4 < 12

So, x=-2 is true.
