Answer:

  $5535.00

Step-by-step explanation:

You want the cost to produce 10 more units if 8 are being produced and the marginal cost function is c'(x) = 0.375x² -x +500.

The cost is the integral of the marginal cost. If we want 10 more units than the 8 being produced, the total cost for those units will be the definite integral of the marginal cost function from 8 to (8+10) = 18.

The attachment shows that integral to have a value of 5535.

The cost to produce 10 more units is $5535.00.

Additional comment

Many graphing calculators can do the numerical integration for you. The integral of the function is ...

  C(x) = x³/8 -x²/2 +500x

The cost of interest is C(18) -C(8).

Expressions represent the number of squares in step n are 1st, 2nd and 5th options.

An equation is a mathematical statement that indicates the equality of two expressions. It contains variables, constants, and mathematical operators such as addition, subtraction, multiplication, and division. Equations can be used to model and solve a wide range of problems in various fields, including physics, engineering, economics, and chemistry.

Step 1: analyze the pattern

If number of squares in each step is expressed as , f(n) then you can see the following results1

The number of squares in 1st step is, f(1)=8........(1)

In second step number of squares is increased by a number of 3. that is, f(2)=f(1) + 3...................(2)

Again in 3rd step, the number of squares increased by 3, that is,

f(3)= f(2) + 3...............(3)

    = (f(1) +3) + 3

    = f(1) + 2 × 3f(3)

    = f(1)+ 2 × 3............(4)

Step 2: make the recurrence relation

Now, from (1), (2) and (3) we can generalize the pattern for a step n such that,

f(1)=8........(1)  f(1) + 3...................(2) f(2) + 3...............(3)

f(n)= f(n-1) + 3 for n≥2

Thus, the 2nd option from the top is correct.

Step 3: find the form of f(n)

Now, from (1), (2) and (4) we can find the number of squares , for a step n such that,

f(1)=8+0×3f(2)= 8+1×3f(3)=8+2×3f(n)= 8+(n-1)×3 for n≥1

or

f(n)=8+3(n-1) for n≥1

Thus, 1st option is correct

f(n)=3n+5 for n ≥1

Thus, 5th option is also correct

Thus, 1st, 2nd and 5th options are the correct answer.

False. The variance is not a measure of central tendency; it is a measure of dispersion or spread in a dataset. Central tendency measures, on the other hand, describe the center or typical value of a dataset. Common measures of central tendency include the mean, median, and mode.

The variance quantifies the average squared deviation of individual data points from the mean. It provides information about how spread out the data points are around the mean. A larger variance indicates greater dispersion, while a smaller variance indicates less dispersion.

To calculate the variance, you compute the average of the squared differences between each data point and the mean. This emphasizes the spread of the data but does not provide information about the central value or typical location of the data.

In conclusion, the variance is a measure of dispersion, not a measure of central tendency. It quantifies how spread out the data points are from the mean, providing insights into the variability of the dataset.

Answer:

The solution to the system is (-6, -9)

Step-by-step explanation:

In order to graph the system, we can find two points belonging to each equation and join them with a line. We look then for the point at which the lines intersect.

(a) Two points for the first line defined by: 3 x + 2 y = -36

What is the value of y when x=0?

3 (0) + 2 y = -36

then y = -36/2 = -18, then one point on this line is (0, -18)

What is the value of x when y = 0?

3 x + 2 (0) = -36

then x = -12, then a second point for this line is: (-12, 0)

When can draw the line that represents this first equation by joining the two points as shown in the attached image with the two points found and the line depicted in orange.

(b) Two points for the second line defined by: - x + 2 y = -12

What is the value for y when  x = 0?

- (0) + 2 y = -12

then y = -12/2 = -6, therefore one point for this line is: (0, -6)

What is the value of x when y = 0?

- x + 2 (0) = -12,

then x= 12,and therefore another point for this line is (12. 0)

When can draw the line that represents this second equation by joining the two points we found, as shown in the attached image with the two points found and the line depicted in blue.

We see that the intersection of the two lnes takes place at  x= -6 and y = -9. That is at the point (-6, -9)

Answer:

5/4

Step-by-step explanation:

slope = rise/run

slope=y2-y1/x2-x1

slope=9-(-1)/15-7=10/8=5/4

So the answer is 5/4.

Answer:

5/ 4

Step-by-step explanation:

slope of a line is the rate of change of y co-ordinates with respect to the change in x co-ordinates.

therefore,

\(slope = \frac{9 - (-1}{15-7) } \\ = \frac{10}{8} \\ = \frac{5}{4} \)

as we were given 2 points the rate of change of x and y co-ordinates will be equal to the difference between the values of each for the two points.

Step-by-step explanation:

To find the result of multiplying vector a by vector b, we use the dot product or scalar product. The dot product of two vectors is calculated by multiplying the corresponding components and summing them up.

Given:

a = [1, 3, 5]

b = [1, 3, 5]

To find a · b, we multiply the corresponding components and sum them:

\(a . b = (1 * 1) + (3 * 3) + (5 * 5)\\ = 1 + 9 + 25\\ = 35\)

So, a · b equals 35.

Now, let's plot the coordinate (35) on a graph paper. Since the coordinate consists of only one value, we'll plot it on a one-dimensional number line.

On the number line, we mark the point corresponding to the coordinate (35). The x-axis represents the values of the coordinates.

First, we need to determine the appropriate scale for the number line. Since the coordinate is 35, we can select a scale that allows us to represent values around that range. For example, we can set a scale of 5 units per mark.

Starting from zero, we mark the point at 35 on the number line. This represents the coordinate (35).

The graph paper would show a single point labeled 35 on the number line.

Note that since the coordinate consists of only one value, it can be represented on a one-dimensional graph, such as a number line.

Step-by-step explanation:

The standard error of the mean for the sample of eight is approximately 3.16.

To calculate the standard error of the mean (SEM), we can use the formula:

SEM = standard deviation / square root of sample size

For the sample of four:

Standard deviation (s) = 5.48

Sample size (n) = 4

SEM = 5.48 / sqrt(4) = 5.48 / 2 = 2.74

Therefore, the standard error of the mean for the sample of four is 2.74.

For the sample of eight:

Standard deviation (s) = 8.93

Sample size (n) = 8

SEM = 8.93 / sqrt(8) ≈ 3.16

Therefore, the standard error of the mean for the sample of eight is approximately 3.16.

Comparing the two samples, the sample of four has a smaller standard error of the mean (2.74) compared to the sample of eight (approximately 3.16). A smaller standard error indicates a more precise estimate of the population mean. Therefore, the sample of four is a better estimate of the population mean compared to the sample of eight.

The area of the figure is approximately 55.77 ft². ( Option A )

To find the area of the composite figure, we need to divide it into two separate shapes:

a trapezoid and a triangle.

First, let's find the length of the base of the trapezoid. We know that one side of the trapezoid is 4 feet, and the other side is 6.7 feet. We also know that the height of the trapezoid is 6 feet. The top side of the trapezoid is labeled as 10.7 feet, but we don't need it to find the area of the trapezoid.

Using the Pythagorean theorem, we can find the length of the diagonal side of the trapezoid:

d = sqrt(4² + 6²)

   = 7.21 feet

Now we can find the length of the base of the trapezoid:

b = 10.7 - 7.21

  = 3.49 feet

The area of the trapezoid is:

A = (1/2) × (b1 + b2) × h

   = (1/2) × (4 + 6.7) × 6

   = 45.3 ft²

Now let's find the area of the triangle. We know that the height of the triangle is 6 feet, and the base of the triangle is 3.49 feet (half of the base of the trapezoid). The area of the triangle is:

A = (1/2) × b × h

   = (1/2) × 3.49 × 6

    = 10.47 ft²

Finally, the area of the composite figure is the sum of the area of the trapezoid and the area of the triangle:

A = 45.3 + 10.47

   = 55.77 ft²

Therefore, the area of the figure is approximately 55.77 ft².

The volume of the original pyramid is, 250/3 cubic inches, and the volume of the reduced size pyramid is, 80/3 cubic inches.

What is the pyramid?

A pyramid is a structure that has triangular exterior surfaces that converge to a single step at the summit, giving it roughly a pyramidal shape in the geometric sense. Any polygonal form, including triangular and quadrilateral, can serve as the base of a pyramid. A pyramid has at least three outside triangle surfaces as a result.

Let, the pyramid has a square base of lengths 5 inches  and the height is 10 inches.

Since,

Volume of pyramid = (l x b x h)/3

where,

l is the base length,

b is the base width and

h is the height.

Here, l = b = 5, h = 10

So,

V = (5 x 5 x 10)/3 = 250/3 cubic inches.

Now, to save costs in production, the lengths of the sides of the base are each reduced by one inch while the pyramid's height remains the same.

So, l = b = 4, h = 10

Therefore,

V = (l x b x h)/3 = (4 x 4 x 10)/ 3 = 80/3 cubic inches.

Hence, the volume of original pyramid is, 250/3 cubic inches and the volume of reduced pyramid is, 80/3 cubic inches.
