The graph of the rational function y = f(x) is represented by the blue line on the graph above. The x-intercept is the point at which the function crosses the x-axis and is labeled (0, 0).

The vertical asymptote at x = 3 is the red line. The local approximation for the vertical asymptote at x = 3 is represented by the black line and is given by y = 568 - 332(x - 3). Similarly, the vertical asymptote at x = -2 is the purple line and the associated local approximation is given by y = -2(x + 2). Finally, the horizontal asymptote at y = 2 is the orange line.

To illustrate the graph, assume the function f(x) is the following: f(x) = (x + 2)(x - 3) / (x + 5). This function is a rational function, as it is the ratio of two polynomials, and it has the given constraints.

To graph the rational function, we begin by finding the x-intercept, which is (0, 0). Then, we look at the vertical asymptote. At x = 3, the local approximation is given by y = 568 - 332(x - 3). We solve the equation y = 568 - 332(x - 3) for x, and get x = 3, thus we mark this point on the graph as the vertical asymptote. We do the same for the vertical asymptote at x = -2 and mark this point on the graph. Finally, we draw the line for the horizontal asymptote at y = 2. This gives us the complete graph of the rational function y = f(x).

In conclusion, the graph of the rational function y = f(x) that displays the four constraints can be sketched and labeled as shown in the figure above.

Answer: 80 meters wide and 100 meters long.

Step-by-step explanation:

Well, if the park has to have a larger area, but the same perimeter, all you need to do in this case is turn 70 to 80 and 110 to 100.

80 + 80 + 100 + 100 = 360 meters in perimeter

70 x 110 = 7700

80 x 100 = 8000   ← This has greater area than the park above

Ann's investment in Cilla Shipping bonds has increased in value more, by $33,605.41

What is purchase price?

The complete cost of purchasing an asset is known as the original cost. The whole costs associated with purchasing and using an asset are taken into account when calculating its initial cost.

To determine which of Ann's investments has increased in value more, we need to compare the current value of the bonds and the stock to their original purchase value.

First, let's calculate the purchase price of the bonds:

7 bonds x $500 par value x 0.95626 market rate = $3,349.82

So, Ann initially invested $3,349.82 in the Cilla Shipping bonds.

Next, let's calculate the purchase price of the stock:

125 shares x $28.00 per share = $3,500.00

So, Ann initially invested $3,500.00 in the Cilla Shipping stock.

Now, let's calculate the current value of the bonds:

7 bonds x $500 par value x 1.06384 market rate = $37,286.48

So, the current value of the bonds is $37,286.48.

Let's also calculate the current value of the stock:

125 shares x $30.65 per share = $3,831.25

So, the current value of the stock is $3,831.25.

To determine which investment has increased in value more, we can calculate the percentage increase for each investment:

Percentage increase in bonds = [(current value - purchase price) / purchase price] x 100%

= [(37,286.48 - 3,349.82) / 3,349.82] x 100%

= 1010.46%

Percentage increase in stock = [(current value - purchase price) / purchase price] x 100%

= [(3,831.25 - 3,500.00) / 3,500.00] x 100%

= 9.48%

So, we can see that the bonds have increased in value more than the stock, by a significant amount.

The bonds have increased in value by 1,010.46%, while the stock has increased in value by only 9.48%. The bonds have increased in value by a total of $33,936.66 ($37,286.48 - $3,349.82), while the stock has increased in value by a total of $331.25 ($3,831.25 - $3,500.00).

Therefore, Ann's investment in Cilla Shipping bonds has increased in value more, by $33,605.41 ($33,936.66 - $331.25).

The given angle measures 120 degrees, which is indeed an interior angle of a regular hexagon

What is hexagon ?

A hexagon is a six-sided polygon, which is a two-dimensional geometric shape with straight sides. The word hexagon comes from the Greek words "hexa" meaning "six" and "gonia" meaning "angle."

To find the value of x in the regular hexagon, we can start by noting that the interior angles of a regular hexagon are all congruent and measure 120 degrees.

Next, we can see that the given angle (11x + 21)° is an interior angle of the hexagon. Therefore, we can set this angle equal to 120 degrees and solve for x:

11x + 21 = 120

11x = 99

x = 9

Therefore, the value of x is 9.

Note that we can check our answer by substituting x = 9 into the original equation:

11x + 21 = 11(9) + 21 = 120

Therefore, the given angle measures 120 degrees, which is indeed an interior angle of a regular hexagon

The polynomial for the number of miles between the two cars is d(t) = 5t + 150

Given that

Car A: 7t²+50t+150

Car B: 7t²+45t

The distance function is represented as

d(t) = 7t²+50t+150 - 7t² - 45t

So, we have

d(t) = 5t + 150

This means that t =3

So, we have

d(3) = 5 * 3 + 150

d(3) = 165

This means that d(t) = 200

So, we have

5t + 150 = 200

Evaluate the difference

5t = 50

So, we have

t = 10

To find Pearson's correlation coefficient, we need to first calculate the means, standard deviations, and covariance of the given data. Let's first convert the heights in km to m for ease of calculation.

t (s) h (m)

0 25,000

5 28,000

10 30,000

15 31,000

25 33,000

30 34,000

(a) Pearson's correlation coefficient:

We can use the formula

r = (nΣxy - ΣxΣy) / sqrt[(nΣx² - (Σx)²)(nΣy² - (Σy)²)]

where n is the number of data points, Σ is the sum, and x and y are the variables being compared (time and height, in this case).

Using the given data, we get:

n = 6

Σx = 85

Σy = 181000

Σx² = 1375

Σy² = 503,710,000

Σxy = 2,886,000

Substituting into the formula, we get:

r = (62,886,000 - 85181000) / sqrt[(61375 - 85²)(6503710000 - 181000²)]

r = 0.994

Therefore, Pearson's correlation coefficient is 0.994, indicating a strong positive correlation between time and height.

(b) Rocket's acceleration:

We can use the formula:

h = ut + (1/2)at²

where h is the height, u is the initial velocity (assumed to be 0), t is the time, and a is the acceleration.

Rearranging, we get:

a = 2h/t²

Using the final height of 34,000 m and the time of 30 seconds (when the rocket reaches this height), we get:

a = 2*34000/(30²)

a = 75.6 m/s²

Therefore, the rocket's acceleration is 75.6 m/s².

If the cost for using 21 HCF of water is $35.39.  the cost for using 56 HCF of water is  $82.64.

We can use the two given data points to find the slope and y-intercept of the linear function that represents the monthly cost of water use.

Let's use (21, 35.39) and (57, 83.99) as our two data points.

First, let's find the slope of the line:

slope = (y2 - y1) / (x2 - x1)

slope = (83.99 - 35.39) / (57 - 21)

slope = 48.6 / 36

slope = 1.35

Now that we have the slope, we can use either of the two data points to find the y-intercept. Let's use (21, 35.39):

y = mx + b

35.39 = 1.35 * 21 + b

35.39 = 28.35 + b

b = 35.39 - 28.35

b = 7.04

So the linear function that represents the monthly cost of water use is:

y = 1.35x + 7.04

where y is the cost (in dollars) and x is the amount of water used (in HCF).

Now we can use this function to find the cost for using 56 HCF of water:

y = 1.35x + 7.04

y = 1.35 * 56 + 7.04

y = 82.64

So the cost for using 56 HCF of water is  $82.64.

Step-by-step explanation:

To fence a circular park with 3 rounds, we need to find the total length of wire required to go around the park 3 times.

The circumference of a circle is given by the formula:

C = πd

where C is the circumference, π is the constant pi, and d is the diameter.

Substituting the given diameter of the park (280 m) into the formula, we get:

C = π * 280 m

≈ 879.65 m

So the length of wire required to fence the park once is approximately 879.65 m.

To fence the park three times, we need to multiply this length by 3:

3 rounds of wire = 3 * 879.65 m

= 2638.95 m

Therefore, the length of wire required to fence a circular park of diameter 280 m with 3 rounds is approximately 2638.95 m.

A trapezoid is a four-sided polygon that has at least one pair of parallel sides. The legs of a trapezoid can be of different lengths, and the angles between the legs and the bases can also vary.

The formula for finding the area of a trapezoid is:

Area = ((Base 1 + Base 2) x Height) / 2

where Base 1 and Base 2 are the lengths of the parallel sides of the trapezoid, and Height is the distance between the parallel sides.

There are several types of trapezoids, including:

Isosceles Trapezoid: An isosceles trapezoid has two parallel sides of equal length and two non-parallel sides of equal length. The angles between the legs and the bases are also equal.

Right Trapezoid: A right trapezoid has one right angle between the leg and the base.

Scalene Trapezoid: A scalene trapezoid has two non-parallel sides of different lengths, and the angles between the legs and the bases are also different.

Let the number in the bottom box=

The missing value in this equation is 4, or (4)/(1) in fraction form.

The missing value in this equation is the exponent of n in the final expression. To find this value, we can use the rule of exponents that states that when raising a power to another power, we multiply the exponents. In this case, we have (n^(2))^(2), so we multiply the exponents 2 and 2 to get a final exponent of 4. Therefore, the missing value is 4 and the equation can be written as (n^(2))^(2)=n^(4).

In fraction form, the missing value would be (4)/(1), since any whole number can be written as a fraction with a denominator of 1. So, the equation can also be written as (n^(2))^(2)=n^((4)/(1)).

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Complex number is,

⇒ - 117 + 14i

Let a = - 117

b = 44

Then, tan ⁻¹ (44/117) = 339.39°

⇒ θ = 339.39°

And, r = √117² + 44² = 125

Hence, We have;

[tex]\sqrt[n]{z} = \sqrt[n]{r} [cos (x + 2\pi k/n) + i sin (x + 2\pi k/n)][/tex]

Where, k = 0,1,2, 3, ..

Now, At k = 0

[tex]\sqrt[3]{z} = \sqrt[3]{125} [cos (339.39 + 0/3) + i sin (339.39 + 0/n)][/tex]

    = - 1.96 + 4.60i

At k = 1;

[tex]\sqrt[3]{z} = \sqrt[3]{125} [cos (339.39 + 360/3) + i sin (339.39 + 360/n)][/tex]

     = - 3.00 - 4.00i

At k = 2;

[tex]\sqrt[3]{z} = \sqrt[3]{125} [cos (339.39 + 360*2/3) + i sin (339.39 + 360*2/3)][/tex]

     = 4.96 - 0.60i

Thus, All Cube roots of complex number - 117 + 14i are,

- 1.96 + 4.60i

- 3.00 - 4.00i

4.96 - 0.60i

The cross product of the first two vectors is -60.

The given vectors are: \( \left(\begin{array}{l}1 \\ 3 \\ 4\end{array}\right),\left(\begin{array}{l}5 \\ 0 \\ 4\end{array}\right),\left(\begin{array}{l}0 \\ 0 \\ 4\end{array}\right) \).

To find the cross product of the first two vectors, we use the formula:

\(\left(\begin{array}{l}a_1 \\ a_2 \\ a_3\end{array}\right) \times \left(\begin{array}{l}b_1 \\ b_2 \\ b_3\end{array}\right) = \left(\begin{array}{l}a_2b_3-a_3b_2 \\ a_3b_1-a_1b_3 \\ a_1b_2-a_2b_1\end{array}\right) \)

Plugging in the values from the given vectors, we get:

\(\left(\begin{array}{l}1 \\ 3 \\ 4\end{array}\right) \times \left(\begin{array}{l}5 \\ 0 \\ 4\end{array}\right) = \left(\begin{array}{l}(3)(4)-(4)(0) \\ (4)(5)-(1)(4) \\ (1)(0)-(3)(5)\end{array}\right) = \left(\begin{array}{l}12 \\ 16 \\ -15\end{array}\right) \)

Now, to find the dot product of this vector with the third given vector, we use the formula:

\(\left(\begin{array}{l}a_1 \\ a_2 \\ a_3\end{array}\right) \cdot \left(\begin{array}{l}b_1 \\ b_2 \\ b_3\end{array}\right) = a_1b_1 + a_2b_2 + a_3b_3 \)

Plugging in the values from the vectors, we get:

\(\left(\begin{array}{l}12 \\ 16 \\ -15\end{array}\right) \cdot \left(\begin{array}{l}0 \\ 0 \\ 4\end{array}\right) = (12)(0) + (16)(0) + (-15)(4) = -60 \)

Therefore, the final answer is -60.

Use the rule, “add 8” to find the cost of 6 T-shirts. The cost of the T-shirt is $48.

One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division.

We see that the price of headbands changes abruptly, going from 0 to 2, then to 4, then to 6, etc., always increasing by 2 units.

The “add 8” rule applies to the price of T-shirts because each one costs $8.

In order to determine the cost of six headbands, we then perform the following calculations:

8 + 8 + 8 + 8 + 8 + 8 = 6 x 8 = $48

We see that we can easily multiply the required quantity of T-shirts by the cost per unit of T-shirts.

Therefore, the cost of the T-shirt is $48.
