Hicksian demand functions are:x1** = 2P₁x₂ ; x₂** = P₂²

Utility function: u(x1+x2) = .5ln(x1) + .25ln(x₂) .The Marshallian demand functions are: x1* = - and x₂* = P₂.

The indirect utility function is found by substituting Marshallian demand functions into the utility function and solving for v(P₁, P₂, Y).u(x1*,x2*) = v(P₁,P₂,Y) ⇒ u(-, P₂) = v(P₁,P₂,Y) ⇒ .5ln(-) + .25ln(P₂) = v(P₁,P₂,Y) ⇒ v(P₁,P₂,Y) = - ∞ (as ln(-) is not defined)

Thus the indirect utility function is undefined.

Minimum expenditure function can be derived from the Marshallian demand function and prices of goods:

Exp = P₁x1* + P₂x2* = P₁(-) + P₂P₂ = -P₁ + P₂²

Minimum expenditure function is thus:

Exp = P₁(-) + P₂²

Hicksian demand functions can be derived from the utility function and prices of goods:

H1(x1, P1, P2, U) = x1*H2(x2, P1, P2, U) = x2*

Hicksian demand functions are:

x1** = 2P₁x₂

x₂** = P₂²

If there are no restrictions on the amount of money the consumer can spend, the Hicksian demand functions for x1 and x2 coincide with Marshallian demand functions.

The required solutions are x = 1 and x = -5

Given is the quadratic equation 3x²+ 12x - 15= 0

Here the first step is to first multiply the first term that is a and the last term c

the given quadratic expression can be generalized as ax² + bx + c = 0

So first multiply 3 and 15 and the product which we will get is 45.

And then try to express this product as the sum of two numbers such that these two numbers difference would be the number which is in the middle that is the alphabet b

So 45 is the product of 15 and 3

and the difference of these two number 15-3 = 12

Thus these are the required numbers

thus we can simply write it as

3x² + 15x - 3x - 15 = 0

3x ( x + 5 ) - 3 ( x + 5 ) = 0

( 3x - 3 ) ( x +5 ) = 0

thus the values of x are

3x - 3 =0

3x = 3 and this implies x = 1

and from the second expression x + 5 = 0

this implies x = -5

The equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be:  \(x-2y=0\)

Step-by-step explanation:

Given the line

\(x-2y=-4\)

\(x+4 = 2y\)

\(y=\left(\frac{1}{2}\right)x+2\)

\(m_1=\frac{1}{2}\)

so, the slope of the line parallel to the given line would have

the same slope as  \(\frac{1}{2}=m\), and passed through the point (0, 0).

Therefore, the equation of the required line is given by

\(y = mx+b\)

\(y=\left(\frac{1}{2}\right)x+0\)

\(y=\left(\frac{1}{2}\right)x\)

\(2y=x\)

\(x-2y=0\)

Therefore,  the equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be:  \(x-2y=0\)

The velocity v of the pendulum is the first derivative of the distance s with respect to time t. That is, \[ v=v(t)=\frac{ds}{dt} \] Similarly, the acceleration a of the pendulum is the first derivative of the velocity v with respect to time t. That is, \[ a=a(t)=\frac{dv}{dt} \] We can find the velocity v and acceleration a by taking the derivatives of the given equation for the distance s. \[ s=s(t)=0.04 \sin (2 t)+3 t \] The first derivative of s with respect to t is \[ v=v(t)=\frac{ds}{dt}=0.08 \cos (2 t)+3 \] The second derivative of s with respect to t is \[ a=a(t)=\frac{dv}{dt}=-0.16 \sin (2 t) \] Now, we can find the velocity v and acceleration a at the given times t= 8π ,t= 4π , and t= 2π by plugging in the values of t into the equations for v and a. \[ v( 8π )=0.08 \cos (2( 8π ))+3=3 \quad \text{m/s} \] \[ v( 4π )=0.08 \cos (2( 4π ))+3=3 \quad \text{m/s} \] \[ v( 2π )=0.08 \cos (2( 2π ))+3=3 \quad \text{m/s} \] \[ a( 8π )=-0.16 \sin (2( 8π ))=0 \quad \text{m/s}^2 \] \[ a( 4π )=-0.16 \sin (2( 4π ))=0 \quad \text{m/s}^2 \] \[ a( 2π )=-0.16 \sin (2( 2π ))=0 \quad \text{m/s}^2 \] Finally, we can graph s=s(t),v=v(t), and a=a(t) by plotting the equations for s, v, and a as functions of t.

The exact area of each hexagonal shape is 181.5sqrt(3) cm^2. Option B

To determine the exact area of each hexagonal shape formed by the equilateral triangles, we need to calculate the area of one equilateral triangle and then multiply it by the number of triangles that make up the hexagon.

The formula to calculate the area of an equilateral triangle is:

Area = (sqrt(3) / 4) * side^2

Given that the side of each tile measures 11 cm, we can substitute this value into the formula to find the area of one equilateral triangle:

Area = (sqrt(3) / 4) * (11 cm)^2

= (sqrt(3) / 4) * 121 cm^2

= 121sqrt(3) / 4 cm^2

Now, since the hexagon is formed by six equilateral triangles, we can multiply the area of one triangle by 6 to find the total area of the hexagon:

Hexagon Area = 6 * (121sqrt(3) / 4 cm^2)

= 726sqrt(3) / 4 cm^2

= 181.5sqrt(3) cm^2

Therefore, the exact area of each hexagonal shape is 181.5sqrt(3) cm^2.

Let the number be represented by "n"

To find the value of the daily salary (X) such that 25% of the daily salaries are greater than X, we need to find the corresponding z-score using the standard normal distribution.

First, we convert the given percentage to a z-score. Since we want the upper 25% (greater than X), the corresponding z-score is the value that leaves 25% in the lower tail. Using a standard normal distribution table or a calculator, the z-score corresponding to 25% is approximately 0.674.

Next, we use the formula for z-score conversion: z = (X - μ) / σ, where μ is the mean and σ is the standard deviation. Plugging in the given values, we have 0.674 = (X - 70) / 10.

Solving for X, we get X = 0.674 * 10 + 70 = 6.74 + 70 = 76.74.

Rounding to one decimal place, the value of the daily salary X is approximately 76.7 JD. Therefore, option 3, 76.7 JD, is the correct answer.

Answer:

Acacia is trying to decide whether to purchase a new sofa and armchair using an installment credit offer from the store or to wait until she has enough cash ...

Step-by-step explanation:

The requreid Acacia would have to pay $459 in interest for the first year of the installment credit offer.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.

SI = Principal×rate×time

If Acacia chooses to take the installment credit offer, she will only pay the interest for the first year. The interest payment for the first year can be calculated as:

Interest = Principal x Rate x Time

where Principal is the amount borrowed, Rate is the interest rate per year, and Time is the time period in years.

Here, Principal is $2,700 and Rate is 17% per year. Since Acacia only pays interest for the first year, Time is 1 year.

So, Interest = 2700 x 0.17 x 1 = $459

Therefore, Acacia would have to pay $459 in interest for the first year of the installment credit offer.

If she chooses to wait until she has enough saved up to pay for the furniture in cash, she would not have to pay any interest. Therefore, she would save $459 by waiting to buy the furniture in cash.
