The  polynomial function graph tat has an end behavior that is different from the rest is option D.

The difference between Option D and the rest is the the starting and ending quadrants  in which they are defined.

Note that Polynomials A to C  start from the 4th quadrant and end in the second  while Option D starts from the 1st and ends in the 3rd.

This means that Set A-C polynomials have beginning points in the fourth quadrant and final points in the second quadrant. The polynomials in set D, on the other hand, have their beginning points in the first quadrant and their ultimate points in the third quadrant.

Answer:

To prove that (a4 +b4 + a2b2+ a2+b2-ab)/a2+b2+ab =1 we can follow the following steps.

Step-by-step explanation:

Factoring the numerator, we get

(a^4 + 2a^2b^2 + b^4 - ab + a^2 + b^2)/(a^2 + b^2 + ab).

we can also write it as

[(a^2 + b^2)^2 - ab + a^2 + b^2]/(a^2 + b^2 + ab).

Expanding  (a^2 + b^2)^2,

we get,

(a^4 + 2a^2b^2 + b^4 - ab + a^2 + b^2)/(a^2 + b^2 + ab).

After cancellation we get

[(a^4 + 2a^2b^2 + b^4) - ab + a^2 + b^2]/(a^2 + b^2 + ab).

By simplifying we get

(a^4 + a^2 + 2a^2b^2 + b^4 - ab + b^2).

At this point, we can see that the numerator is the same as the denominator, resulting in (a^2 + b^2 + ab)/(a^2 + b^2 + ab), which simplifies to 1.

Therefore, we have proved that (a4 +b4 + a2b2+ a2+b2-ab)/a2+b2+ab =1

The value of the probability P(W) is (d) .0.1878

From the question, we have the following parameters that can be used in our computation:

P(W|¬L) = 0.18, P(¬W|L) = 0.24, P(L) = 0.13

Using the complement probability, we have

P(¬L) = 1 - 0.13

Evaluate

P(¬L) = 0.87

Using the conditional probability formula, we have

P(W|¬L) = P(W and ¬L)/P(¬L)

P(¬W|L) = P(¬W and L)/P(L)

So, we have

P(W and ¬L)/0.87 = 0.18

P(¬W and L)/0.87 = 0.24

So, we have

P(W and ¬L) = 0.1566

P(¬W and L) = 0.2088

Using P(W and ¬L) = 0.1566, we have

P(W) * P(¬L) = 0.1566

So, we have

P(W) * 0.87 = 0.1566

Evaluate

P(W) = 0.18

The closest to this is 0.1878

Hence, the value of P(W) is  0.1878

The logarithm equation is solved and the equivalent value of c = 17

Given data ,

To solve the equation log₂ 4 + log₂ (c-9) = 5, we can combine the logarithms using logarithmic properties.

Using the property log a + log b = log (a x b), the equation becomes:

log₂ (4(c-9)) = 5

To eliminate the logarithm, we can rewrite the equation in exponential form. In exponential form, the equation becomes:

2⁵ = 4(c-9)

Simplifying the left side:

The value of x for each item is given as follows:

a) x = 3.9.

b) x = 32.6º.

The three trigonometric ratios are the sine, the cosine and the tangent, and they are obtained according to the rules presented as follows:

For item a, we have that x is opposite to the angle of 63º, while 2 is the adjacent side, hence:

tan(63º) = x/2

x = 2 x tangent of 63 degrees

x = 3.9.

For item b, we have that x is the angle, while 7 is the opposite side and 13 is the hypotenuse, hence:

sin(x) = 7/13

x = arcsin(7/13)

x = 32.6º.

The integral is solved where A = 2√ln(x) + c and the equation diverges.

Given data ,

Let the integral be represented as A

where the value of A is

A = ∫( 2 to ∝ ) ( 1/x√ln(x) )

Let the value of u = ln(x)

So, Taking the derivative of both sides with respect to x:

du/dx = 1/x

Rearranging the equation, we get:

dx = du / (1/x) = x du

Now, we can substitute the value of dx and the expression for u in terms of x into the integral:

∫(2 to ∞) 1 / (x * √(ln(x))) dx = ∫(ln(2) to ∞) 1 / (√u) du

On simplifying the integral , we get

3 (x = (-1 ± √3) / 3) .So, option a is the correct answer.

To find the solutions of the quadratic equation 3x^2 - 6x + 2 = 0, we can use the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 3, b = -6, and c = 2. Substituting these values into the formula, we have:

x = (-(-6) ± √((-6)^2 - 4(3)(2))) / (2(3))

x = (6 ± √(36 - 24)) / 6

x = (6 ± √12) / 6

x = (6 ± 2√3) / 6

x = (3 ± √3) / 3

Therefore, the exact solutions of the equation 3x^2 - 6x + 2 = 0 are:

The equilibrium point for James T-shirt business is (P, Q) = (7, 24).

To find the equilibrium point (P, Q) for James T-shirt business

we need to set the demand function equal to the supply function and solve for the values of P and Q.

Demand function: P = -Q + 31

Supply function: P = Q - 17

Setting them equal:

-Q + 31 = Q - 17

Adding Q to both sides and subtracting 31 from both sides:

2Q = 48

Dividing both sides by 2:

Q = 24

Now, we can substitute this value of Q into either the demand or supply function to find the corresponding value of P.

P = Q - 17

P = 24 - 17

P = 7

Area = (θ/360) * π * r^2

Where θ is the central angle in degrees, π is the mathematical constant pi, and r is the radius of the circle.

Given that the central angle is 225° and the radius is 5 cm, we can plug these values into the formula:

Area = (225/360) * 3.14 * (5)^2

The total for everything cannot be $1.70,  the individual costs and calculate the total cost separately.

the price of each notebook is N cents and the price of each sheet of colored paper is P cents.

The cost of the pencils can be calculated as follows:

For the 2 pencils at 2 cents each: 2 pencils * 2 cents/pencil = 4 cents

the horizontal measurement of the second garden, we multiply the original horizontal dimension (x) by the horizontal scale factor (75% or 0.75):

Horizontal measurement of the second garden = x * 0.75.

the vertical measurement of the second garden, we multiply the original vertical dimension (y) by the vertical scale factor (150% or 1.5):

Vertical measurement of the second garden = y * 1.5.

Therefore, the horizontal measurement of the second garden is x * 0.75 feet, and the vertical measurement of the second garden is y * 1.5 feet.

values for x and y, so we cannot provide exact measurements for the second garden. The given scale factors only allow us to determine the proportional changes in dimensions. If you have specific values for x and y, you can substitute them into the formulas above to find the corresponding measurements for the second garden.

Using the points (1, 100) and (8, 800):

To solve the given linear programming project, address each question and step one by one:

The inequality for the advertising budget is:

500x + 1200y ≤ 9000

The constraint for the maximum number of magazine ads is:

y ≤ 6

The constraint for the maximum number of TV ads is:

x ≤ 7

The constraint for the minimum number of TV ads is:

x ≥ 0

The constraint for the minimum number of magazine ads is:

y ≥ 0

Now move on to the estimation of the line of best fit:

For the points (1, 150) and (6, 900):

To find the slope of the line, use the formula:

slope = (change in y) / (change in x)

slope = (900 - 150) / (6 - 1)

slope = 750 / 5

slope = 150

To write the equation of the line, use the point-slope form:

y - y1 = m(x - x1), where (x1, y1) is a point on the line

Taking (1, 150) as the point:

y - 150 = 150(x - 1)

y - 150 = 150x - 150

y = 150x

The slope tells us the increase in sales for each TV ad. In this case, the slope of 150 means that for every TV ad, CD sales increase by 150.

For the points (1, 100) and (8, 800):

To find the slope of the line, use the formula:

slope = (change in y) / (change in x)

slope = (800 - 100) / (8 - 1)

slope = 700 / 7

slope = 100

To write the equation of the line, use the point-slope form:

y - y1 = m(x - x1), where (x1, y1) is a point on the line

Taking (1, 100) as the point:

y - 100 = 100(x - 1)

y - 100 = 100x - 100

y = 100x

The slope tells us the increase in sales for each magazine ad. In this case, the slope of 100 means that for every magazine ad, CD sales increase by 100.

In conclusion:

The equation for the line of best fit for TV ads is y = 150x.

The equation for the line of best fit for magazine ads is y = 100x.

For each TV ad, CD sales increase by about 150.

For each magazine ad, CD sales increase by about 100.

Step-by-step explanation:

Since it is asking multiple people it can result in data. It can't result in data if it asks just one question to someone

The rate of change of the line that contains the given points is 0.75 or 3/4.

To determine the rate of change of the line that contains the given points, we can calculate the slope of the line.

The slope represents the rate of change between any two points on a line.

Using the formula for slope (m) between two points (x₁, y₁) and (x₂, y₂):

m = (y₂ - y₁) / (x₂ - x₁)

Let's calculate the slope using the given points (-4, -7), (0, -4), and (8, 2):

For the points (-4, -7) and (0, -4):

m₁ = (-4 - (-7)) / (0 - (-4))

= (-4 + 7) / (0 + 4)

= 3 / 4

= 0.75

For the points (0, -4) and (8, 2):

m₂ = (2 - (-4)) / (8 - 0)

= (2 + 4) / 8

= 6 / 8

= 0.75

The slope is the same for both pairs of points, which means the line is a straight line and has a constant rate of change.
