1) It is a conservative force, yes.

2) At (5m, 5m), the potential energy is 20 J.

1) If the work that a force performs when moving an item depends only on the object's initial and final positions and not on the path travelled, the force is said to be conservative.

Let's verify if this condition is met for the force in this problem:

- For moving from (0 m, 0 m) to (5 m, 5 m), the work done is 20 J (A)

Then we can go from (0 m, 0 m) to (5 m, 5 m) through a different path:

- from (0 m, 0 m) to (5 m, 0 m) (work done: 25 J)

- from (5 m, 0 m) to (5 m, 5 m) (work done: -5 J)

Total work done in the second path: 25 J + (-5 J) = 20 J --> same as (A)

We can also go from (0 m, 0 m) to (5 m, 5 m) through a different path:

- from (0 m, 0 m) to (0 m, 5 m) (work done: 35 J)

- from (0 m, 5 m) to (5 m, 5 m) (work done: -15 J)

Total work done in the third path: 35 J + (-15 J) = 20 J --> same as (A)

So, the force is conservative, since the work done does not depend on the path taken.

2) For a conservative force, the change in potential energy of the object moved by the force is equal to the work done by the force in moving the object from A to B.

Here have:

Point A: (0m, 0m)

Point B: (5m, 5m)

In this problem, the potential energy at the origin (point A) is zero, so,

[tex]W = U_{b} - U_{a}[/tex]

Also we know that the work done is W = 20 J

So, we find

[tex]U_{b} = W + U_{a}\\=20 + 0\\= 20J[/tex]

A force does work on a 50 g particle as the particle moves along the following straight paths in the xy-plane: 25 J from (0 m, 0 m) to (5 m, 0 m); 35 J from (0 m, 0 m) to (0 m, 5 m); -5 J from (5 m, 0 m) to (5 m, 5 m); -15 J from (0 m, 5 m) to (5 m, 5 m); and 20 J from (0 m, 0 m) to (5 m, 5 m).

Is this a conservative force?

If the zero of potential energy is at the origin, what is the potential energy at (5m, 5m)?

The equation the line perpendicular to the line given is y = -x/4+2

The slope of a line is a number that describes both the direction and the steepness of the line.

Given that, a line is perpendicular to y = 4x + 8 and passes through (−8, 4).

The equation of general line is; y = mx+c, where m is the slope.

We know that, two lines perpendicular to each other will have slope negative reciprocal of each other.

Therefore, the slope of the asked line is -1/4

Finding for c,

4 = -1/4x(-8)+c

c = 4-2

c = 2

Therefore, equation will be; y = -x/4 +2

Hence, The equation the line perpendicular to the line given is y = -x/4+2

Steady state vector represent the long term market share of both groceries i.e WB and ZA. The long term market share of ZA is 0.727...

The steady-state behavior of a Markov chain is the long-term probability that the system is in each state. In other words, no matter how many transitions are applied to the system, it does not affect the state vector.

We have, WB and ZA are two competing grocery stores.

Probability that a customer who shops this week at WB will shop again here next week , p₁= 64% = 0.64

Probability(not shop again from WB) = 1-p₁

= 1 - 0.64 = 0.36

Probability that a customer who shops this week at ZA will shop again here next week , p₂ = 76% = 0.76

P(not shop again from ZA) = 1- p₂= 1 -0.76

= 0.24

Let market share of WB and ZA be "x" and "y" respectively, So, steady state vectors , s = [x y]

and x + y = 1 ---(*)

The Transition matrix, P=[1- p₁ p₁ ; 1-p₂ p₂]

P = [ 0.36 0.64 ; 0.24 0. 76 ]

we have to determine the value of x and y . So, we solve the following matrix equation, s[ I - P] = 0

matrix where I is identity matrix of 2×2

=> s([ 1 0 ; 0 1 ] - [0.36 0.64 ; 0.24 0. 76 ] ) = [0 0 ; 0 0 ]

=> s[1- 0.36 0- 64 ; 0 - 0.24 1 -0.76]

=[0 0 ; 0 0]

=> s[ 0.64 - 0.64 ; - 0.24 0.24] = [0 0;0 0]

=> [ x y] [0.64 -0.64 ; -0.24 0.24] = [0 0; 0 0]

Matrix multiplication,

=> [ 0.64x - 0.24y ; - 0.64x + 0.24y ]

= [ 0 0 ; 0 0]

equating the LHS and RHS

0.64x - 0.24y = 0 --(1)

- 0.64x + 0.24y = 0 --(2)

If we multiply equation (1) by -1 then we get equation(2). So, both equations are identical and we can collpase them in one equation for further calculation. Now, we have to equations

0.64x - 0.24y = 0 --(3)

x + y = 1

we can solve these equations either matrix method or substitution. We use here substitute

x = 1- y in equation (3) we get

0.64x - 0.24y = 0=> 0.64(1 - y) - 0.24 y = 0

=> 0.64 - 0.64y - 0.24 y = 0

=> 0.64 = 0.88y

=> y = 0.64/0.88 = 8/11 = 0.727

from equation (*) , x = 1 - 8/11 = 3/11 = 0.272

So, Market share of grocery ZA is y i.e 0.727.

Sample Size:

Sample size is defined as the number of observations used to determine estimates for a given population. Sample size was drawn from the population. Sampling is the process of selecting a subset of individuals from a population to estimate characteristics of the population as a whole. The number of entities within a subset of the population is selected for analysis

According to the Question:

The Necessary Sample Size is calculated as follows:

Necessary Sample Size =

a) The height of the rectangular shower stall is ( 3x - 2 )

b) The volume of the shower stall when x = 4 is 240 feet³

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

a)

Let the width of the rectangular shower stall be W = x

Let the length of the rectangular shower stall be L = ( x + 2 )

Let the height of the rectangular shower stall be H = H

Now , the equation will be

The volume of the rectangular shower stall is V = 3x³ + 4x² - 4x

And ,

Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

3x³ + 4x² - 4x = x ( x + 2 ) H

On simplifying the equation , we get

3x³ + 4x² - 4x = ( x² + 2x ) H

Dividing by ( x² + 2x ) on both sides of the equation , we get

H = ( 3x - 2 )

Therefore , the value of L is ( 3x - 2 )

On substituting the value for H in equation for volume of rectangular stall ,

Volume of rectangular shower stall = x ( x + 2 ) ( 3x - 2 )

Volume of rectangular shower stall = ( x² + 2x ) ( 3x - 2 )

Volume of rectangular shower stall = 3x³ + 4x² - 4x

Therefore , the height of the shower stall is ( 3x - 2 )

b)

The volume of rectangular shower stall = 3x³ + 4x² - 4x

when the value of x = 4

Substitute the value for x = 4 in the equation , we get

Volume of rectangular shower stall = 3x³ + 4x² - 4x

Volume of rectangular shower stall = 3 ( 4 )³ + 4 ( 4 )² - 4 ( 4 )

Volume of rectangular shower stall = 3 x 64 + 4 x 16 - 16

Volume of rectangular shower stall = 192 + 64 - 16

Volume of rectangular shower stall = 240 feet³

Therefore , the volume of the rectangular shower stall is 240 feet³

Hence , a) The height of the shower stall is ( 3x - 2 )

b) The volume of the shower stall when x = 4 is 240 feet³

In 4 months, the total cost of Yoga Studio A would equal that of Yoga Studio B

What is total ?

Total refers to an entire or complete amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.

The cost of Yoga Studio A at any given month can be represented as:

= Membership fee + (Monthly fee x Number of months)

Assuming number of months is x, the formula would be:

= 24 + (21.50 × x)

= 24 + 21.50x

Yoga Studio B would be:

= 41 + (17.25 × x)

= 41 + 17.25x

In order to find the month that these costs would be equal, equate both formulas:

24 + 21.50x = 41 + 17.25x

21.50x - 17.25x = 41 - 24

4.25x = 17
