The cost function for producing $x$ items of a certain brand of barstool is given by C(x)=0.01x3-0.6x2+13x+200.

(a) C(x)=0.03x3- 0.12x2+13

(b) MC(50)=-82 dollars per barstool.

It approximately represents the cost of producing the 50th barstool.

(c) The exact cost of producing the 51st barstool is C51=C50+MC(50)=$28.91 dollars.

(d) Using C(50) and MC (50), the total cost of producing 53 barstools is approximately C50+(53-50) MC(50)=$229.82.

Step-by-step explanation:

\(\frac{(x-2)}{y} =z\)

Use cross multiplication.

\(( x - 2 ) = yz\)

Now, to make y the subject divide both sides by z.

\(\frac{( x - 2 )}{z} = y\)

Since the p-value (0.3257) is greater than the significance level (α = 0.05), we fail to reject the null hypothesis.

The null hypothesis is the argument in scientific study that no link exists between two sets of data or variables being investigated.

The null hypothesis states that any empirically observed difference is due only to chance, and that no underlying causal link exists, thus the word "null."

When a null hypothesis is rejected this means that there is not enough empirical evidence to support the claim which in this is case is  that more than 58% of adults would erase all of their personal information online if they could.

The graph of the function f(x) = ln(x-1) is a logarithmic curve that approaches a vertical asymptote at x = 1. The x-intercept can be found by setting f(x) = 0 and solving for x.

a) Graph of f(x) = ln(x-1):

The graph of ln(x-1) is a curve that is undefined for x ≤ 1 because the natural logarithm function is not defined for non-positive values. As x approaches 1 from the right side, the function increases towards positive infinity. The vertical asymptote is located at x = 1.

b) Finding the x-intercept:

To find the x-intercept, we set f(x) = ln(x-1) equal to zero:

ln(x-1) = 0.

Exponentiating both sides using the properties of logarithms, we get:

x-1 = 1.

Simplifying further, we have:

x = 2.

Therefore, the x-intercept is at x = 2.

In summary, the graph of f(x) = ln(x-1) is a logarithmic curve with a vertical asymptote at x = 1. The x-intercept of the graph is at x = 2.

This criterion can be defined based on the desired level of accuracy or when the change in the estimated parameters falls below a certain threshold.

When implementing a program for a nonlinear problem using the least square adjustment technique, it is essential to determine a termination condition. This condition dictates when the program should stop iterating and provide the final estimated parameters. A common approach is to set a convergence criterion, which measures the change in the estimated parameters between iterations.

One possible criterion is to check if the change in the estimated parameters falls below a predetermined threshold. This implies that the adjustment process has reached a point where further iterations yield minimal improvements. The threshold value can be defined based on the desired level of accuracy or the specific requirements of the problem at hand.

Alternatively, convergence can also be determined based on the objective function. If the objective function decreases below a certain tolerance or stabilizes within a defined range, it can indicate that the solution has converged.

Considering the chosen termination condition is crucial to ensure that the program terminates effectively and efficiently, providing reliable results for the nonlinear problem.

Factor using LCF (Least Common Factor which is x)

\( \displaystyle \large{x(7 {x}^{2} + 4)}\)

Chaperones = 8 and Student = 117

Step-by-step explanation:

Let,

Chaperones = x

Student = y

x + y = 125

=> x = 125 - y (1)

23x + 16y = 2056

=> 23(125 - y) + 16y = 2056

=> 2875 - 23y + 16y = 2056

=> 2875 - 7y = 2056

=> 2875 - 2056 = 7y

=> 819 = 7y

=> 819/7 = y

=> 117 = y

From 1

=> x = 125 - 117

=> x = 8

Under the assumption of simple harmonic motion, the package will be at x = 4.50 centimeters at a time of 0.805 seconds.

Simple harmonic motion is a kind of periodic motion represented by sinusoidal functions. Physically speaking, it is a good approximation for periodic motion due to small perturbations and with absence of frictions and viscous forces on the system.

The position of an object under simple harmonic motion is described by the following equation:

x (t) = A · cos (2π · t / T + Ф)      (1)

Where:

If we know that T = 5 s, A = 8.50 cm, Ф = 0 rad and x = 4.50 cm, then the time when the package will reach x = 4.50 cm is:

4.50 = 8.50 · cos (2π · t / 5)

9 / 17 = cos (2π · t / 5)

0.322π = 2π · t / 5

t = 0.805 s

10. Answer choice A

5 feet 4 inches is approximately equal to 162.56 cm.

The conversion is the process of changing the unit of one quantity to another units  

The conversion factor is defined as the number that is used to change one unit to another units by multiplying or dividing

To convert, we can use the following conversion factors:

1 foot = 30.48 cm

1 inch = 2.54 cm

Therefore, 5 feet = 5 x 30.48 = 152.4 cm

And 4 inches = 4 x 2.54 = 10.16 cm

Adding them together, we get:

152.4 cm + 10.16 cm = 162.56 cm

So, 5 feet 4 inches is 162.56 cm.

The given question is incomplete, the complete question is :

What is 5ft 4inches in centimeter?

Work Shown:

r = 6 = radius

V = volume of a sphere of radius r

V = (4/3)*pi*r^3

V = (4/3)*pi*6^3

V = 904.77868423386

V = 904.8

I used my calculator's stored version of pi (instead of something like pi = 3.14)

The units "cubic meters" can be abbreviated to m^3 or \(m^3\)

The volume of the given sphere is 904.8 cubic meters. Thus, option B is the answer.

         The volume of a sphere can be calculated using the formula:

V = \(4/3 * \pi * r^3\),

Where V is the volume and r is the radius of the sphere.

\(\pi\) = 3.14

The radius of the sphere (r) = 6m

Plugging in the given radius of 6m into the formula, we get:

V = (4/3) * \(\pi\) * (6^3)

V = 1.333 * \(\pi\) * 216

V = 1.333 * 3.14 * 216

V = 4.1866 * 216

V = 904.8 cubic meters

Therefore, when the radius of the sphere is 6m, the volume of the sphere is 904.8  cubic meters.

Answer:

Jumping up 10 steps

Step-by-step explanation:

In a quadrilateral, the sum of the interior angles is always 360 degrees.

Given the information provided, we have the following:

The left side is labeled "four x plus twelve."

The right side is labeled "sixty."

To find the value of x, we need to set up an equation based on the given information and solve for x.

The sum of the interior angles can be represented as:

(4x + 12) + 60 = 360

Combining like terms:

4x + 72 = 360

Subtracting 72 from both sides:

4x = 360 - 72

4x = 288

Finally, dividing both sides by 4:

x = 288 / 4

Simplifying:

x = 72

Solving a system of equations we can see that:

First, let's define the variables:

With the given information we can write 3 equations:

A = (3/4)*V

V = K - $18

A + V + K = $386.4

Then we need to solve a system of equations:

A = (3/4)*V

V = K - $18

A + V + K = $386.4

We can first replace the first equation into the third to get:

(3/4)*V + V + K = $386.4

And rewrite the second to get:

k = V + $18

And replace that in the other equation:

(3/4)*V + V + V + $18 = $386.4

Now we can solve this for V:

V*(1 + 1 + 3/4) = $386.4 - $18

V*(11/4) = $368.40

V = (4/11)*$368.40 = $133.96

Now that we know the value of V, we can replace it in:

K = V + $18 = $133.96 + $18 = $151.96

A = (3/4)*V = (3/4)*$133.96 = $100.47
