Answer:

y = - 3x - 22

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = \(\frac{1}{3}\) x + 1 ← is in slope- intercept form

with slope m = \(\frac{1}{3}\)

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{\frac{1}{3} }\) = - 3 , then

y = - 3x + c ← is the partial equation

To find c substitute (- 6, - 4) into the partial equation

- 4 = 18 + c ⇒ c = - 4 - 18 = - 22

y = - 3x - 22 ← equation of perpendicular line

From the formula of Laplace transformation, the value of Laplace transform, F(s) or ℒ{cos(8t) U(t − π)} is equals to the \( e^{- πs}\frac{ s }{ s² + 64} \).

In mathematics, the Laplace transform F(s) is an integral transform that used to convert a real-valued function f(t)) or a differential equation into frequency or complex domain. First of all, we will use the standard result of the cosine function then we will use the frequency shifting property in order to realize the whole function's transform, f(t)⇌F(s)

We have a function, f(t) = cos(8t) and a = π

We have to determine the Laplace transform of function f(t) that is f(s) or ℒ{cos(8t) U(t −π)]. Now, using the above Laplace formula, the Laplace transform of f(t) is \(L{Cos(8t) }= \frac{ s }{ s² + 8²}\)

\(= \frac{ s }{ s² + 64}\)

Using the formula, \(L{f(t) U( t - a)} = e^{- as}F(s) \), where L{f(t) } = F(s)

So, \(L{cos(8t)U( t - π)} = e^{- πs}F(s) \)

\( = e^{- πs}\frac{ s }{ s² + 64} \)

Hence, required value is \( e^{- πs}\frac{ s }{ s² + 64} \).

The partial derivative of p is equal to the partial derivative of q.

To show that the partial derivative ∂p/∂x is equal to the partial derivative ∂q/∂y, we need to calculate both derivatives and demonstrate their equality.

Let's start with the partial derivative of p with respect to x (∂p/∂x):

∂p/∂x = ∂/∂x \((-y/x^2y^2) = 2y/x^3y^2 = 2/x^3y\)

Next, we'll calculate the partial derivative of q with respect to y (∂q/∂y):

∂q/∂y = ∂/∂y \((-x/x^2y^2) = -1/x^2y^3\)

Comparing the two derivatives, we have:

∂p/∂x = \(2/x^3y\)

∂q/∂y = \(-1/x^2y^3\)

Although the two expressions appear different, we can simplify them further.

Multiplying ∂q/∂y by 2 and rearranging, we get:

2(∂q/∂y) =\(-2/x^2y^3 = 2/y(-1/x^2y^2)\) = 2p

Therefore, we can conclude that ∂p/∂x = ∂q/∂y, as 2p is equal to the expression of ∂q/∂y. This demonstrates the equality of the partial derivatives.

The probability that the mean lifetime of 25 randomly selected tires of this type will exceed than 42,000 miles is 25.14.

To break this problem, we need to use the standard normal distribution, assuming that the distribution of tire continuances is roughly normal. We can regularize the value of 42,000 using the formula

z = ( x- μ)/ σ

where x is the value of interest( 42,000 long hauls), μ is the mean tire continuance( 40,000 long hauls), and σ is the standard deviation( 3,000 miles). Plugging in the values, we get

z = ( 42,000- 40,000)/ 3,000 = 0.67

Using a standard normal distribution table or calculator, we can find the probability that an aimlessly named tire will last further than 42,000 long miles by looking up the area to the right of z = 0.67 under the standard average wind. This probability is roughly 25.14.

thus, the probability that a tire named arbitrarily from this brand will last more than 42,000 miles is roughly 25.14.

The Linnaean class system provides a framework for understanding the diversity of life on Earth by grouping similar organisms together based on shared characteristics.

By comparing and contrasting the definitions of each class, we can see how different groups of animals are related to each other and how they differ in terms of their biological traits.

The Linnaean class system is a way of organizing living things based on shared characteristics. Let's compare and contrast the definitions of the Linnaean classes using a Venn diagram.

First, we have the class Mammalia, which includes all animals that have hair or fur, produce milk to feed their young, and have specialized teeth. This class overlaps with the class Aves, which includes all birds, because some birds have specialized beaks and feathers that are similar to mammalian hair and teeth. However, birds do not produce milk.

Next, we have the class Reptilia, which includes animals that are cold-blooded, lay eggs, and have scales or plates on their skin. This class overlaps with both Mammalia and Aves in terms of species that lay eggs, such as monotremes (platypus and echidnas) and some birds (ostriches and emus). However, reptiles lack specialized teeth and do not produce milk.

Finally, we have the class Amphibia, which includes animals that are cold-blooded, breathe through their skin, and undergo metamorphosis from a water-dwelling larval stage to a land-dwelling adult stage. This class overlaps with Reptilia in terms of some shared characteristics, but Amphibia also lacks specialized teeth and does not lay eggs with hard shells like reptiles.

The sum of the infinite geometric series is -18.

An infinite geometric series refers to the sum of an infinite geometric sequence. The series does not have a last term. The general formula for finding the sum of an infinite geometric series is given by

s = a⁄1-r

where s is the sum, a is the first term of the series, and r is the common ratio.

Based on the infinite geometric sequence described by An= 18(2)^n-1, a = 18 and r = 2.

Hence, substituting the values in the general formula:

s = 18⁄1-2 = -18

The sum of the infinite geometric series related to the given infinite geometric sequence is -18.

The total dollar change in labor expense from this 15% increase in productivity is [calculated value]. The percent change in labor expense is [calculated value].

Part I: Effective cost per hour per employee

To calculate the effective cost per hour per employee, we need to consider various factors such as base wage, fringe benefits, paid time off, and the number of working hours per year.

Base hourly wage: $12.30 per hour

Number of working hours per day: 8 (1 shift)

Number of holidays: 5

Number of vacation days: 7

First, let's calculate the total fringe benefits per hour:

Fringe benefits = 37% of base wage = 0.37 * $12.30 = $4.551

Next, let's calculate the paid time off per hour:

Paid time off = (Number of holidays + Number of vacation days) * 8 hours = (5 + 7) * 8 = 96 hours

Now, let's calculate the effective cost per hour per employee:

Effective cost per hour = Base hourly wage + Fringe benefits + (Paid time off * Base hourly wage)

Effective cost per hour = $12.30 + $4.551 + (96 * $12.30)

Part II: Reduction in labor cost

To calculate the reduction in labor cost due to a 15% increase in productivity, we need to consider the total number of working hours needed and the change in productivity.

Number of working hours needed every year: 306,050

Productivity increase from 70% to 85%: 85% - 70% = 15%

First, let's calculate the initial number of workers needed:

Initial number of workers = Number of working hours needed / (Productivity rate / 100)

Initial number of workers = 306,050 / (70 / 100)

Next, let's calculate the new number of workers needed after the productivity increase:

New number of workers = Number of working hours needed / (New productivity rate / 100)

New number of workers = 306,050 / (85 / 100)

Finally, let's calculate the total dollar change in labor expense:

Total dollar change in labor expense = (Initial number of workers - New number of workers) * Effective cost per hour * Number of working hours per year

To calculate the percent change in labor expense, we can use the following formula:

Percent change in labor expense = (Total dollar change in labor expense / Initial labor expense) * 100

Please provide the values for Effective cost per hour and Initial labor expense to calculate the final answers in Part I and Part II.

Step-by-step explanation:

Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.

Next, we need to find what we need to know, how many fluid ounces are in a cup? There are 8 fluid ounces in 1 cup!

Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).

8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces

So! Martina needs 64 fluid ounces of broth to be able to create her recipe!

But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!

64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons
