consider an economy with 200 workers. assume the marginal product of labor (mpl) is 10 and the value of the marginal product of labor (vmpl) is $90. what is the market price (p)?

The function is increasing for all real values of x where

x < –1 and where x > 4.

What is increasing and decreasing functions?

Calculus uses a function's derivative to determine whether a function is increasing or decreasing at various intervals in a specific domain. For a given function, y = F(x), the function is known as an increasing function if the value of y increases as the value of x increases, and the function is known as a decreasing function if the value of y decreases as the value of x increases.

Given function is

f(x) = (x - 4)(x + 1)

If f(x) = 0,  x=4 & x=-1

f'(x) = 0, x=3/2

So, we will check the behavior of the function in the neighborhood of  x=4,-1, 3/2.

What is the increasing and decreasing function?

A function is said to be an increasing function if its slope is continuously increasing in a given interval.

A function is said to be a decreasing function if its slope is continuously decreasing in a given interval.

If x>4

Let us check at x=5

f(5) =6(+ve)

f(x) >0 for x>4

So, the function is increasing in x>4

Similarly, If x <-1

f(x) >0 for  x <-1

So, function is increasing in x <-1

If -1<x<3/2

f(x)<0 for -1<x<3/2

So, function is decreasing in -1<x<4

If 3/2<x<4

f(x)>0 for 3/2<x<4

So, the function is increasing in 3/2<x<4

From the graph too, we can see the behavior of the given function

by observing the slope.

We can see that for x<-1 and x>4, the slope is continuously increasing

So, the function is increasing in x<-1 and x>4.

Therefore, the function is increasing for all real values of x where

x < –1 and where x > 4.

Answer:

It will take approximately 36.4 weeks for Melissa and Chris to have the same amount of money.

Step-by-step explanation:

To determine how many weeks it will take for Melissa and Chris to have the same amount of money, you can set up an equation based on the information given. Let W be the number of weeks it takes for Melissa and Chris to have the same amount of money.

Melissa's total amount of money after W weeks will be 5000 + 20W.

Chris's total amount of money after W weeks will be 6820 - 50W.

Therefore, you can set up the equation 5000 + 20W = 6820 - 50W and solve for W.

First, you can add 50W to both sides of the equation to get 50W + 5000 = 6820.

Next, you can subtract 5000 from both sides of the equation to get 50W = 1820.

Finally, you can divide both sides of the equation by 50 to get W = 36.4.

The issue with this model is that purchases with a cost of $30 appear to be negative, which is impractical in real-world situations.

This is due to the model's linear best fit line's potential for being inaccurate for the end points.

A linear probability model:

Purchasei = 1.7-0.06×pricei

For an increase in $20 in price,

Change in purchase = -0.06 × 20

change in purchase = -1.2

There would be 1.2 less purchase.

Purchase at price of $10 is:

Purchase 10= 1.7 ×0.06 × 10

Purchase 10 = 1.1

Purchase at price of $30 is:

Purchase 30 = 1.7 × 0.06 × 30

Purchase 30 = -0.1

This is the problem with this model that the purchases at price of $30 is coming as negative which is not possible in practical situation.

It is because that the linear best fit line of the model which might not be accurate for the end points.

Correct option is A

Independent variable

Independent variable is manipulated by the researcher to determine the effect of its change relative to a change in dependent variable.

Independent Variables

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

In an experiment the independent variable is the variable that is varied or manipulated by the researcher. The dependent variable is the response that is measured. One way to think about it is that the dependent variable depends on the change in the independent variable.

Qualitative research consist in observing some variables and obtaining information. Usually the qualitative research does not involve the manipulation of independent variables, these types of researches focuses more in collecting answers in groups of people, and making statistics with those answers or information. So the variables are not manipulated.

Answer:

Yes

Step-by-step explanation:

y-8= -8(x-2)  ==> solve for y

y = -8(x - 2) + 8  ==> add 8 on both sides to isolate y

y = (-8 * x - 2(-8)) + 8  ==> distribute -8 to x and -2 using the distribution

                                         property

y = (-8x - (-16)) + 8 ==> simplify

y = (-8x + 16) + 8  ==> subtracting by a negative number is equivalent to

                               adding by a positive number.

y = -8x + 16 + 8

fn is an integrable function on [a, b]. further, assume that the sequence (fn) converges uniformly to f on [a, b]. f is integrable on integral [a, b].

Let ε > 0. Since (fn) converges uniformly to f on [a, b], there exists an N such that |fn(x) - f(x)| < ε for all x ∈ [a, b] and all n ≥ N.

Since fn is integrable on [a, b], it follows that

∫a b|fn(x)|dx < ∞ for all n ≥ N.

We have

∫a b|f(x)|dx ≤ ∫a b|fn(x)|dx + ∫a b|fn(x) - f(x)|dx

Since |fn(x) - f(x)| < ε, it follows that

∫a b|f(x)|dx ≤ ∫a b|fn(x)|dx + ε(b - a)

Answer:

y - 2.5 = 2(x - 1)

Step-by-step explanation:

Here given slope is 2 and the point through which the straight line passes is (1, 2.5)

Let the equation be y = mx + c where m and c represent slope and y intercept respectively.

We know the slope, so we input that in our equation

y = 2x + c ------- i

This straight line also passes through (1, 2.5)

Putting the values in place of x and y we get,

2.5 = (2X1) + c

⇒ 2.5 = 2 + c

⇒ c = 2.5 - 2

⇒ c = 0.5

Now, putting value of c in i, we get

y = 2x + 0.5 -------- ii

It can also be written as y - 2.5 = 2(x - 1) ------- iii

this equation and ii are same and you can verify that by simplifying iii, by multiplying 2 and then shifting the -2.5 from LHS to RHS

The table of values represents a quadratic function. And a quadratic function is y = x² / 10.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function.

Linear functions have constant first differences.

Here,  if a and b is the first and second term.

Then the first difference is b-a.

Quadratic functions have constant second differences.

Let the first differences are:

b-a = m, c-b = n

Then the second difference is n-m.

Exponential functions have a constant ratio.

The ratio of first term and second term is b/a.

Here, from the table;

y₂-y₁ = 0.4 - 0.9 = -0.5 = m₁

y₃-y₂ = 0.1 - 0.4 = -0.3 = m₂

y₄-y₃ = 0 - 0.1 = -0.1 = m₃

y₅-y₄ = 0.1 - 0 = 0.1 = m₄

y₆-y₅ = 0.4 - 0.1 = 0.3 = m₅

From the first differences, we have no idea about the function property.

So, the second differences:

m₂ -  m₁ = -0.3 + 0.5 = 0.2

m₃ - m₂ = -0.1 + 0.3 = 0.2

m₄ - m₃ = 0.1 + 0.1 = 0.2

m₅ - m₄ = 0.3 - 0.1 = 0.2

Here, the second differences are constant 0.2.

And the common ratio is varying.

So, quadratic functions have constant second differences.

And the quadratic function is y = x² / 10.

Therefore, the given function is a quadratic function.

The value of y is 4.

Generally, To find the value of y in the expression [0 (3z-9) (y-1)], we need to isolate y. To do this, we can start by combining like terms:

[-1(4x-2) -5] [-1 2 -5] [0 (3z-9) (y-1)] [0 3 2]

Becomes:

[-4x + 2 - 5] [0 3 2]

Then we can rearrange the terms to get:

[-4x - 5 + 2] [0 2 + 3]

This simplifies to:

[-4x - 3] [5]

Finally, we can isolate y by dividing both sides by 2:

[-4x - 3] / 2 = 5 / 2

This gives us:

y = (5/2) + 3/2

Simplifying, we find that y = 4.

The slope-intercept form of a linear equation is given by the equation y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

Given that the slope of the line is 1 and it passes through the point (8, –1), we can use the point-slope form of a linear equation to write the equation in slope-intercept form. The point-slope form is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Substituting the values given in the problem into the point-slope form, we get:

y - (-1) = 1(x - 8)

Expanding the right side and rearranging the terms, we get:

y + 1 = x - 8

y = x - 9

According to the given question:

Equation of circle in polynomial form is X²+ Y²- 6X - 2Y + 6 = 0

Converting to standard form using completing the square method

X²+ Y²- 6X - 2Y + 6 = 0

(X² - 6X) + (Y² - 2Y) = -6

(X² - 6X + 9) + (Y² - 2Y + 1) = -6 + 9 + 1

The value of the expression (f * g) by using two ways that is by direct integral and by Laplace transform is equal to (1/2)e^t/(1-t) - (1/2)e^t/(1+t) + C.

To compute the convolution of f(t) and g(t) by directly evaluating the integral in the definition of the convolution, we have:

(f * g)(t) = ∫f(w)g(t-w)dw

Substituting in the expressions for f(t) and g(t), we have:

(f * g)(t) = ∫e^w*e^(-6)(t-w)dw

This integral can be evaluated as follows:

(f * g)(t) = ∫e^(-5w)dw

(f * g)(t) = (-1/5)e^(-5w) + C

(f * g)(t) = (-1/5)e^(-5w) + C

To compute the convolution of f(t) and g(t) by computing the inverse Laplace transform of the product of the Laplace transforms of f(t) and g(t), we have:

F(s) = L{f(t)} = ∫f(t)e^(-st)dt = ∫e^t*e^(-st)dt = 1/(s-1)

G(s) = L{g(t)} = ∫g(t)e^(-st)dt = ∫e^(-6t)*e^(-st)dt = 1/(s+6)

Therefore,

F(s)G(s) = (1/(s-1))(1/(s+6)) = 1/(s^2-1)

To find the inverse Laplace transform of F(s)G(s), we use the following formula:

L^-1{F(s)G(s)} = ∫F(s)G(s)e^st ds

Substituting in the expression for F(s)G(s), we have:

L^-1{F(s)G(s)} = ∫(1/(s^2-1))e^st ds

This integral can be evaluated as follows:

L^-1{F(s)G(s)} = (1/2)e^st/(s-1) - (1/2)e^st/(s+1) + C

L^-1{F(s)G(s)} = (1/2)e^st/(s-1) - (1/2)e^st/(s+1) + C

Thus, the convolution of f(t) and g(t) can be computed either by directly evaluating the integral in the definition of the convolution or by computing the inverse Laplace transform of the product of the Laplace transforms of f(t) and g(t). In both cases, the result is:

(f * g)(t) = (1/2)e^t/(1-t) - (1/2)e^t/(1+t) + C
