The cash collection from customers which adds the change in accounts receivable to the sales for the year 2014 is $749,000. Option C is the correct answer.

To determine the cash collected from customers during 2014, we need to find out the change in accounts receivable from the beginning to the end of the year.

The change in accounts receivable is calculated as follows:

Change in accounts receivable = Accounts receivable, December 31, 2014 - Accounts receivable, December 31, 2013

= $63,000 - $67,000

= -$4,000

The negative sign indicates a decrease in accounts receivable, meaning that cash was collected from customers.

Now, to find the cash collected from customers, we need to add the change in accounts receivable to the sales for the year:

Cash collected from customers = Sales - Change in accounts receivable

= $745,000 - (-$4,000)

= $749,000

When calculating the composite shape's area, the value of x that is needed is: x = 3.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.

The following is the rectangle's area formula:

Area = length*width

Thus;

Area of rectangle = 21x

Area of rectangle = 16 * 3x = 48x

Since the total area is 207 cm², then we have;

21x + 48x = 207

The rate of change for the function f(x) is 9.5 over the interval.

How I calculated the rate of change for f(x):

f(2) = 12, f(6) = 50

slope = (50 - 12) / (6 - 2) = 9.5

The rate of change for the function g(x) is -2 over the interval.

How I calculated the rate of change for g(x):

g(2) = -10, g(6) = -18

slope = (-18 - (-10)) / (6 - 2) = -2

To find the rate of change for a function over an interval, we need to calculate the slope of the secant line that connects the two endpoints of the interval.

The slope of a line can be found using the formula:

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

For the quadratic function f(x) = (x + 1)² + 8, we can find the values of f(2) and f(6) by substituting x = 2 and x = 6 into the function:

f(2) = (2 + 1)² + 8 = 12

f(6) = (6 + 1)² + 8 = 50

Therefore, the rate of change for f(x) over the interval 2 ≤ x ≤ 6 is:

slope = (f(6) - f(2)) / (6 - 2) = (50 - 12) / 4 = 9.5

So the answer is: The rate of change for f(x) is 9.5 over the interval.

To find the rate of change for the linear function g(x) = -2x - 6, we can use the same formula:

g(2) = -2(2) - 6 = -10

g(6) = -2(6) - 6 = -18

Therefore, the rate of change for g(x) over the interval 2 ≤ x ≤ 6 is:

slope = (g(6) - g(2)) / (6 - 2) = (-18 - (-10)) / 4

slope = -2

So the answer is: The rate of change for g(x) is -2 over the interval.

The surface area of the tetrahedral die is 1353 square millimeters

To find the surface area of the tetrahedral die, we need to find the area of each of the four equilateral triangular faces and add them together.

The formula for the area of an equilateral triangle is A = (√(3)/4) x s², where s is the length of the side.

In this case, the base edge of the tetrahedral die is 26 millimeters, so the length of each side of the equilateral triangles is also 26 millimeters.

Using the formula for the area of an equilateral triangle, we can find the area of one face:

A = (√(3)/4) x 26²

A = 338.3 square millimeters (to the nearest tenth)

Since there are four faces, we can multiply the area of one face by 4:

4 x 338.3 = 1353.2 square millimeters

Therefore, the surface area of the tetrahedral die is approximately 1353 square millimeters (to the nearest ten square millimeters).

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

we can use the central angle and the fact that a full circle has a central angle of 360° to calculate the fraction of the circumference that AB represents.

Since the central angle, APB is 45°, we can calculate the fraction of the circumference that AB represents as:

45°/360° = 1/8

Therefore, AB represents 1/8 of the circumference of the circle.

If we let C be the circumference of the circle, then the length of AB can be calculated as:

AB = (1/8) * C

Since we do not know the value of C, we cannot calculate the exact length of AB. However, we can leave our answer in terms of π as:

AB = (1/8) * π * d

where d is the diameter of the circle.

If the diameter of the circle is 8ft, then the radius (r) is half of that, or 4ft. We can now use this value to find the exact length of AB.

The circumference (C) of the circle can be found using the formula:

C = 2πr

where π is the constant pi.

Plugging in the given value of the radius, we get:

C = 2π(4ft) = 8πft

Therefore, the exact length of AB is:

AB = (1/8) * C = (1/8) * 8π ft = π ft

Hence, the exact length of arc AB is π feet. To round to the nearest hundredths, we get:

AB ≈ 3.14 feet

The length of the second shelf is 98 centimeters.

Let's denote the length of the first shelf as x centimeters. According to the problem, we have the following equations for the lengths of the other shelves:

Second shelf: 2x + 18 cm

Third shelf: x - 12 cm

Fourth shelf: x + 4 cm

Robert must use the entire 2.5-meter board for the shelves, so the sum of the lengths of the four shelves should be equal to 2.5 meters, or 250 centimeters. Thus, we can write an equation:

x + (2x + 18) + (x - 12) + (x + 4) = 250

Simplify the equation:

x + 2x + 18 + x - 12 + x + 4 = 250

Combine like terms:

6x + 10 = 250

Subtract 10 from both sides:

6x = 240

Now, divide by 6:

x = 40

Now that we have the length of the first shelf (x = 40 cm), we can find the length of the second shelf:

Second shelf = 2x + 18 = 2(40) + 18 = 80 + 18 = 98 cm

So, the length of the second shelf is 98 centimeters.

Answer:

114 cm

Step-by-step explanation:

Let's start by finding the shortest shelf.

The second shelf is 18 centimeters longer than twice the length of the first shelf. The first shelf is smaller than the second shelf.

The third shelf is 12 centimeters shorter than the first shelf. The third shelf is shorter than the first shelf, so, the third shelf is the shortest shelf.

Let's call the length of the third shelf s.

We know that the third shelf is 12 centimeters shorter than the first shelf. In other words, s is 12 centimeters shorter than the first shelf. So, we can write the length of the first shelf as:

[tex]s+12[/tex]

We also know that the second shelf is 18 cm longer than twice the length of the first shelf.

Start by multiplying the length of the first shelf by 2.

[tex]2(s+12)=2s+24[/tex]

Now, let's add 18.

[tex]2s+24+18=2s+42[/tex]

So, the length of the second shelf is 2s+42.

The remaining shelf is 4 centimeters longer than the first shelf. Remember that the first shelf is s+12. Let's add 4.

[tex]s+12+4=s+16[/tex]

So, the first shelf is s+12, the second shelf is 2s+42, the third shelf is s, and the remaining shelf is s+16.

When you add them all together, you will get the 2.5 meter board.

2.5 meters is equal to 250 cm.

So, the first shelf plus the second shelf plus the third shelf plus the remaining shelf is equal to the entire board, or 250 cm.

Let's rewrite that in terms of s:

[tex](s+12)+(2s+42)+s+(s+16)=250=\\5s+70=250=\\5s=180=\\s=36[/tex]

We now know that s=36 cm.

The problem asks how long the second shelf is. Recall that the second shelf is 2s+42.

Let's plug in 36 to this expression:

[tex]2s+42=\\2(36)+42=\\72+42=\\114[/tex]

So, the second shelf is equal to 114 cm.

Answer:

x = 18°
