The factorization of 2x² - 2x - 3x + 9 using the box method is (2x - 3)(x - 3).

To factor the trinomial 2x² - 2x - 3x + 9 using the box method, we first draw a box and divide it into four sections:

   | 2x  -3 |

   |--------|

   | -2x  9 |

Then, we fill in the top left section with the coefficient of the leading term, 2x, and the bottom right section with the constant term, 9.

   | 2x  -3 |

   |--------|

   | -2x  9 |

Next, we find two numbers that multiply to 2x * 9 = 18 and add to the coefficient of the middle term, -2x - 3x = -5x.

One way to do this is to factor out 2 from the leading two terms, giving 2x² - 2x - 3x + 9 = 2x(x - 1) - 3(x - 3), and then finding the product of (x - 1) and (x - 3) using the AC method:

AC method:

2x(x - 1) - 3(x - 3) = 2x(x - 1) - 3x + 9 - 3(-1)

We can then place these two numbers in the remaining two sections of the box:

   | 2x  -3 |

   |--------|

   | -2x  9 |

   | 2x  -3 |

   |--------|

   | -2x  9 |

   |--------|

   | -3   1 |

We can now factor the trinomial by taking the common factor out of each row and column of the box:

2x(x - 1) - 3x + 9 - 3(-1)

= (2x - 3)(x - 3)

Therefore, the factorization of 2x² - 2x - 3x + 9 using the box method is (2x - 3)(x - 3).

Surface area of the shape is 32 inch².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

The shape consists of 4 rectangular faces and 2 square faces.

Length of rectangular face = 3 inch

Width of rectangular face = 2 inch

Area of rectangular face = Length × Width

                                         = 3 inch × 2 inch

                                         = 6 inch²

Area of 4 rectangular faces = 4 × 6 inch² = 24 inch²

Area of a square face = 2 inch × 2 inch

                                     = 4 inch²

Area of 2 square face = 2 × 4 inch² = 8 inch²

Total area of the shape = 24 inch² + 8 inch² = 32 inch²

Answer:x − x^{2} − 1.

Step-by-step explanation:

Answer:

Part A)

5th and 6th Choices

Part B)

\(\displaystyle y=\frac{1}{4}x^2-x-4\)

Step-by-step explanation:

We are given a parabola with focus at (2, -4) and the directrix given by y = -6.

Part A)

Since our directrix is an equation of y, the distance from any point (x, y) on the parabola to the directrix will simply be the absolute value of the difference of the y-values. Hence:

\(d_1=|y-(-6)|=|y+6|\)

Again, we will use the distance formula. Let the point (x, y) be (x₂, y₂) and our focus (2, -4) be (x₁, y₁). Then by the distance formula:

\(d_2=\sqrt{(x-2)^2+(y-(-4))^2}=\sqrt{(x-2)^2+(y+4)^2\)

Hence, our answers are the 5th and 6th choices.

Part B)

By definition, any point (x, y) on the parabola is equidistant to the focus and the directrix. Hence:

\(\sqrt{(x-2)^2+(y+4)^2}=|y+6|\)

Square both sides. We may remove the absolute value as anything squared yields a positive. Hence:

\((x-2)^2+(y+4)^2=(y+6)^2\)

Square:

\((x^2-4x+4)+(y^2+8y+16)=(y^2+12y+36)\)

Rearrange:

\((x^2-4x+20)-(36)=(y^2-y^2)+(12y-8y)\)

Combine like terms:

\(x^2-4x-16=4y\)

Divide both sides by 4. Hence, our equation is:

\(\displaystyle y=\frac{1}{4}x^2-x-4\)

Answer: both

Step-by-step explanation:

Correlational statistics quantify the strength of a relationship between variables but do not provide information about causality because they cannot assess the temporal sequence of variables.

Correlational statistics, such as correlation coefficients, measure the degree of association between variables.

They indicate the strength and direction of the relationship but do not establish a cause-and-effect relationship. This limitation arises because correlational analysis does not allow for determining the temporal sequence of variables, which refers to the order in which the variables occur or change.

Without knowledge of the temporal sequence, we cannot ascertain whether one variable causes the other or if they are both influenced by an external factor. To establish causality, additional research methods such as experimental designs or longitudinal studies are necessary, where variables can be manipulated or observed over time, respectively.

Thus, correlational statistics serve as valuable tools for understanding associations but do not provide insights into causation.

Answer:

x = 5/13

Step-by-step explanation:

Given \(x \frac{4}{x} - \frac{6}{4x} = \frac{1}{10}\):

First, cancel out the fraction of the first term:

\(x\frac{4}{x}\) = 4

This leaves you with:

\(4 - \frac{6}{4x} = \frac{1}{10}\)

Cancel out the common factor (of 2) from the second term, -6/4x:

\(4 - \frac{3}{2x} = \frac{1}{10}\)

Next, we need to find the LCM of 2x and 10, which is 10x:

Multiply the terms by the LCM = 10x:

\((10x) 4 - \frac{3}{2x} (10x) = \frac{1}{10} (10x)\)

Simplify:

40x - 15 = x

Subtract x from both sides:

40x - x - 15 = x - x

39x - 15 = 0

Add 15 to both sides:

39x - 15 + 15 = 15

39x = 15

Divide both sides by 39 to solve for x:

39x/39 = 15/39

x = 5/13

Answer:

£73.71

Step-by-step explanation:

Let's compute first for the cost of the ticket in 2014. Let x be the increase in the cost of the ticket. If the cost of the ticket is 8% of £65, then the expression should be like this:

Let's add £5.2 to £65 ⇒ £5.2 + £65 = £70.2

The cost of the season ticket in 2014 is £70.2.

Next, we'll have to compute the cost of the ticket in 2015. Let y be the increase in cost of the ticket. If the cost of the ticket is 5% of £70.2, then the expression should be like this:

Let's add £3.51 to £70.2 ⇒ £3.51 + £70.2 = £73.71

The cost of the season ticket in 2015 is £73.71. This is also the cost of the season ticket after two price increases.

a) The expected completion time of the project is 22 units, and the critical path is A-D-F-G-I-J-L. (b) Activities E and G can be performed simultaneously without delaying the minimum project completion time because they are not on the critical path. Performing them concurrently would not affect the critical path activities.

(c) One person can perform activities A, G, and I without delaying the project because these activities are not dependent on each other. As long as the person can complete these activities within their respective durations, the project timeline will not be affected.

(d) If activity G is delayed by seven hours and activity L is delayed by four hours, the project would be delayed by the longest duration among the critical path activities affected by these delays. In this case, the project would be delayed by seven hours since activity G is on the critical path.

(a) The PERT/CPM network is constructed by identifying the activities and their respective durations. Arrows represent the flow of activities, and nodes represent the start and end points of each activity. By calculating the earliest start time, earliest finish time, latest start time, latest finish time, and slack for each activity, the critical path and expected completion time can be determined.

(b) To determine if activities E and G can be performed simultaneously, we analyze their dependencies and impact on the critical path. If performing both activities concurrently does not affect any activities on the critical path, they can be done simultaneously without delaying the project completion time.

(c) Activities A, G, and I can be performed by one person without delaying the project if they have sufficient time and resources to complete these activities within their durations. As long as the dependencies of these activities are taken into account, one person can handle them simultaneously.

(d) To calculate the delay caused by specific activity delays, we analyze the critical path and identify the activities affected by the delays. The project's delay would be equal to the longest duration among the critical path activities impacted by the delays.

The PERT/CPM network provides a visual representation of the project activities, their dependencies, and durations. By identifying the critical path and expected completion time, the project's timeline can be understood. Analyzing the dependencies and impacts of specific activity delays allows us to determine the potential delays to the project completion. It is important to consider the critical path and dependencies when assessing the effect of delays or performing activities concurrently.

Step-by-step explanation:

Add up all the stuff she bought.

Multiply by 23% or .23 then subtract what you get from that to the total of what she bought in all. There is your answer.

the 50th integer in the list is 31245.

To find the 50th integer in the list of positive five-digit integers that use each of the digits 1, 2, 3, 4, and 5 exactly once, we can determine the pattern of the list and then find the corresponding number.

Since the digits 1, 2, 3, 4, and 5 can be arranged in 5! = 120 different ways, there are 120 five-digit integers that can be formed. To determine the 50th integer, we need to find the number at the halfway point of the list.

To organize the list, we can consider the first digit:

- The first digit can be any of the five numbers (1, 2, 3, 4, or 5).

- For each choice of the first digit, the remaining four digits can be arranged in 4! = 24 different ways.

So, there are 5 * 24 = 120 different arrangements, forming the entire list.

To find the 50th integer, we divide 50 by 24 and round up to the nearest whole number:

50 / 24 ≈ 2.0833

Rounding up, we get 3.

Therefore, the 50th integer in the list is formed by choosing the third digit for the first position. We then arrange the remaining four digits in ascending order, resulting in the number 31245.

Answer:

y = (-3/2)x + 4.

Step-by-step explanation:

y - 4 = (2/3)(x - 9)

y = (2/3)x - (2/3)(9) + 4

y = (2/3)x - 2

The slope of this line is 2/3.

A line that is perpendicular to this line will have a slope that is the negative reciprocal of 2/3. To find the negative reciprocal, we flip the fraction and change the sign:

slope of perpendicular line = -3/2

Now we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is a point on the line.

Substituting the given point (6,-5) and the slope -3/2, we get:

y - (-5) = (-3/2)(x - 6)

y + 5 = (-3/2)x + 9

y = (-3/2)x + 4

Therefore, the equation of the line that is perpendicular to y - 4 = (2/3)(x - 9) and passes through the point (6,-5) is y = (-3/2)x + 4.

The vector orthogonal to the plane through the points P, Q, and R is (8, -8, 12), and the area of triangle PQR is \($\sqrt{301}$\).

For part (a), we can find a nonzero vector orthogonal to the plane through the points P, Q, and R by constructing a normal vector to the plane using the cross product of two vectors in the plane. The two vectors in the plane are \($\vec{PQ} = (1- (-2), 0-1, 1-3) = (3, -1, -2)$\) and \($\vec{PR} = (1-4, 0-2, 1-5) = (-3, -2, -4)$\). Taking the cross product of the two vectors gives us the normal vector to the plane, \($\vec{n} = \vec{PQ} \times \vec{PR} = (8, -8, 12)$\). Therefore, the vector orthogonal to the plane is \($\vec{n} = (8, -8, 12)$.\)

For part (b), the area of triangle PQR can be found using the formula for Heron's Formula, which states that the area of a triangle with sides a, b,and c is given by

\($A = \sqrt{s(s-a)(s-b)(s-c)}$\)

where \($s = \frac{a+b+c}{2}$\) . In this case, the sides are \($a = \|\vec{PQ}\| = \sqrt{3^2 + (-1)^2 + (-2)^2} = \sqrt{14}$, $b = \|\vec{QR}\| = \sqrt{(-2-4)^2 + (1-2)^2 + (3-5)^2} = \sqrt{14}$\), and\($c = \|\vec{PR}\| = \sqrt{(-3)^2 + (-2)^2 + (-4)^2} = \sqrt{29}$\). Plugging these values into the formula, we get

\(= \sqrt{s(s-a)(s-b)(s-c)} = \sqrt{\frac{7(7-\sqrt{14})(7-\sqrt{14})(7-\sqrt{29})}{4}} = \sqrt{7(7-\sqrt{14})^2(7-\sqrt{29})} = \sqrt{7(7-\sqrt{14})^2(\sqrt{14}+\sqrt{29})} = \sqrt{7(7-\sqrt{14})^2\sqrt{43}} = \sqrt{301}$\)Therefore, the area of triangle PQR is \($\sqrt{301}$\)

If there is 200 feet of fencing available, the maximum possible area of the corral is 5000 Feet.

In the question, if there is 200 feet of fencing available, then we have to find the maximum possible area of the corral.

The formula of area of rectangle is:

A = L × B, where L is the length of the rectangle and B is the breadth of the rectangle.

The A = 200 feet and rectangular area is enclosed using the creek as one side and fencing for the other three sides, to create a corral.

So, L + 2B = 200

Subtract L on both side, we get

2B = 200 - L

Divide by 2 on both side, we get

B = 100 - L/2

A = f(L)

A = L·(100 - L/2)

A = 100L - \(L^2\)/2

Now finding the derivative.

A' = \(\frac{df(L)}{dL}\)

A' = -L + 100

Let A' = 0

-L + 100 = 0

Subtract 100 on both side, we get

-L = -100

L = 100 feet

Now putting the value of L in B = 100 - L/2.

B = 100 - 100/2

B = 100 - 50

B = 50 feet

The maximum possible area of the corral = 100 × 50

The maximum possible area of the corral = 5000 Feet
