Answer:

  increasing: x > 0

Step-by-step explanation:

Given a table of function values, you want to know the interval on which the function is increasing.

A function is increasing if f(x)-values get larger when x-values get larger. As we go down the table, the x-values get larger.

In the first three lines of the table, the f(x)-values are getting smaller. The function is decreasing on that interval, x < 0.

In the last three lines of the table, the f(x) values are getting larger. The function is increasing on that interval, x > 0.

__

Additional comment

The point (0, 0) represents a minimum. The function is not increasing or decreasing at that point, so the interval of interest is x > 0, not x ≥ 0.

The length of the square garden is s = ( 3x - 4 ) feet

Given data ,

Let the length of the square garden be s

Now , The area of a square is given by the formula A = s², where s is the length of one side of the square.

We are given that the area of the garden is:

A = 9x² - 24x + 16

To find the length of the garden, we need to take the square root of the area:

s = √(A)

Substituting the given expression for A, we get:

s = √(9x² - 24x + 16)

We can simplify this expression by factoring the quadratic under the square root sign:

s = √[(3x - 4)(3x - 4)]

Using the property that the square root of a product is equal to the product of the square roots, we can simplify further:

s = (3x - 4)

Hence , the length of the garden is 3x - 4 feet

Answer: Vertical text sets are arranged in columns from top to bottom, while horizontal text sets are arranged in rows from left to right. The major differences between the two include:

Readability: Vertical text sets may be more difficult to read for individuals who are accustomed to reading horizontally, while horizontal text sets may be more natural for them to read.

Space utilization: Vertical text sets can utilize space more efficiently, especially in situations where vertical space is available, such as in tall and narrow posters or banners. Horizontal text sets, on the other hand, can utilize space more efficiently in situations where horizontal space is available, such as in wide-screen displays or landscape-oriented documents.

Cultural conventions: In some cultures, such as Japan and China, vertical text sets are traditionally used for writing, while in other cultures, such as the United States, horizontal text sets are the norm. Thus, the use of one or the other may depend on cultural context.

One situation where vertical text sets may be more beneficial is in designing a tall and narrow billboard. In this case, a horizontal text set may be difficult to read from afar, while a vertical text set can make use of the available space and be easily read from a distance. On the other hand, in designing a website, horizontal text sets may be more beneficial as they can utilize the full width of the screen and provide more space for additional content.

The correct representations of the inequality is

- 6x + 15 < 10 - 5x  and An open circle is at 5 and a bold line starts at 5 and is pointing to the right.

We have the inequality -3(2x - 5) < 5(2 - x)

Now, simplifying each side of inequality

-3(2x - 5) = -3(2x) + -3(-5)

-3(2x - 5) = - 6x + 15

and, 5(2 - x) = 5(2) + 5(-x)

5(2 - x) = 10 - 5x

So, - 6x + 15 < 10 - 5x

Now, Subtract 15 from both sides

- 6x < -5 - 5x

- x < - 5

x > 5

The correct statements are:

- 6x + 15 < 10 - 5x  and An open circle is at 5 and a bold line starts at 5 and is pointing to the right.

Using the binomial probability formula, we get a probability of approximately 1 or 100%.

This problem involves a binomial probability distribution, where we are interested in the number of successes (colleges with distance learning courses) in a fixed number of trials (picking 13 institutions), where each trial has a constant probability of success (the probability that a college offers distance learning courses).

We can use the binomial probability formula

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

where X is the number of successes, k is the number of successes we are interested in, n is the total number of trials, p is the probability of success, and C(n, k) is the binomial coefficient.

Substituting the given values, we get

P(X = k) = C(13, k) * 0.96^k * 0.04^(13-k)

To find the probability that at least one college offers distance learning courses, we can find the probability that none of the 13 colleges offer distance learning courses and subtract it from 1

P(X ≥ 1) = 1 - P(X = 0)

P(X = 0) = C(13, 0) * 0.96^0 * 0.04^13 = 0.000000005096

P(X ≥ 1) = 1 - 0.000000005096 ≈ 1

Therefore, the probability that at least one college out of 13 offers distance learning courses is approximately 1 or 100%.

Eric will need at least 6 cans of finish to cover the entire outside of the box with three coats.

To find the minimum number of cans of finish needed for the job, we first need to calculate the total surface area of the box that will be covered with the finish.

The box has a length of 42 inches, a depth of 24 inches, and a height of 20 inches. To find the total surface area, we can use the formula for the surface area of a rectangular prism:

Surface area = 2(length x width + width x height + height x length)

Surface area = 2(42 x 24 + 24 x 20 + 20 x 42)

Surface area = 2(1008 + 480 + 840)

Surface area = 6656 square inches

Since the finish will be applied in three coats, we need to multiply the total surface area by three to get the total area of finish needed:

Total area of finish = 3 x 6656 square inches

Total area of finish = 19968 square inches

Now we can convert the total area of finish from square inches to square feet by dividing by 144:

Total area of finish = 19968 square inches / 144 = 138.67 square feet

Since each can of finish covers about 27.5 square feet, we can calculate the minimum number of cans needed by dividing the total area of finish by the coverage of each can:

Minimum number of cans = 138.67 square feet / 27.5 square feet per can

Minimum number of cans = 5.04 cans

Answer: It will cost $2.88 to frame Jayla's math certificate with the fancy frame.

Step-by-step explanation: To calculate the cost of framing Jayla's math certificate, we need to determine the perimeter of the certificate, which is the sum of the lengths of all four sides.

Perimeter = 2 × (height + width)

Perimeter = 2 × (19 + 29)

Perimeter = 2 × 48

Perimeter = 96 centimeters

So the perimeter of the certificate is 96 centimeters.

To find the cost of framing, we need to multiply the perimeter by the cost per centimeter of the fancy frame:

Cost = perimeter × cost per centimeter

Cost = 96 × $0.03

Cost = $2.88

Therefore, it will cost $2.88 to frame Jayla's math certificate with the fancy frame.

The quarterly dividend payment per share based on the question above will be: $0.02.

The close price for the week will be: $5.45.

For one to find the closing price for the week, we have to divide the total cost of the shares by using the number of shares that was bought so it will be:

Close price = Total cost / Number of shares

                    = $2,790.40 / 512

                    = $5.45

To know the quarterly dividend payment per share, we have to calculate the annual dividend payment per share before we can get it so it will be:

Annual dividend per share = Total annual dividend / Number of shares

                                              = $40.96 / 512

                                                = $0.08

From the question, the dividend was paid quarterly, we then divide the annual dividend per share by 4 so as to get the quarterly dividend per share:

Quarterly dividend per share = Annual dividend per share / 4

                                                  = $0.08 / 4

                                                   = $0.02

The rate of change of the circular area is increasing at a constant rate of 12π square feet per second when the radius is exactly 3 feet.

To solve this problem, we need to use the formula for the area of a circle:

[tex]A = πr^2[/tex],

where A is the area and r is the radius.

We also need to use the chain rule of differentiation because we are dealing with a changing radius over time.

First, we can find the rate of change of the area with respect to time (dA/dt) by differentiating the formula for the area:

dA/dt = 2πr(dr/dt)

where dr/dt is the rate of change of the radius with respect to time, which is given as 2 feet per second in the problem.

Therefore, we can substitute these values into the formula to get:

dA/dt = 2π(3)(2)

dA/dt = 12π

So, the rate of change of the circular area is increasing at a constant rate of 12π square feet per second when the
