Part E: The area that Jordan can walk around is equal to the area of a circle with a radius of 6 feet is 113 square feet.

Part A: Wendell cannot make a triangular garden using pieces A, B, and F because the sum of the lengths of the two shorter sides of a triangle (in this case, pieces A, B, and F) must be greater than the length of the longest side (in this case, piece F, which is 2 feet long) in order for the triangle to be a valid one. Since the sum of the lengths of pieces A and B is 12 feet, which is greater than the length of piece F, it is not possible to make a triangular garden using these pieces.

Part B: Wendell cannot make a triangular garden using pieces D, E, and F because the sum of the lengths of the two shorter sides of a triangle (in this case, pieces D, E, and F) must be greater than the length of the longest side (in this case, piece D, which is 8 feet long) in order for the triangle to be a valid one. Since the sum of the lengths of pieces E and F is 5 feet, which is less than the length of piece D, it is not possible to make a triangular garden using these pieces.

Part C: Wendell can make a rectangular garden with the pieces of wood he has by using pieces A and C or pieces B and D. He cannot use pieces E and F because they are not long enough to make up one of the sides of a rectangle.

Part  D: Wendell can not create two triangular gardens using all six pieces of wood as the sum of the lengths of the two shorter sides of a triangle must be greater than the length of the longest side, and he only have 3 pieces with length greater than 3 feet which is required to create one triangle.

Wendell can create two rectangular gardens using all six pieces of wood by using pieces A and C, and pieces B and D.

Part E: The area that Jordan can walk around is equal to the area of a circle with a radius of 6 feet (since the chain is 12 feet long).

The formula to calculate the area of a circle is πr^2

where π is approximately 3.14 and

r is the radius of the circle,

so the area that Jordan has to walk around is approximately

Answer:

No.

Step-by-step explanation:

A linear function can be identified if the function is a line when graphed or if the x is to the first power. X is to the third power, so it's not linear.

Hope it helped!

If three inches are cut off each piece, the expression represents the new total length of all five pieces of wood will be 5 x (initial length) - 15 .

To derive the expression:

Multiply 5 (the number of pieces) times the initial length of each piece
5 x (initial length)

Subtract 3 (the amount cut off each piece) times 5 (the number of pieces)

5 x (initial length) - (3 x 5)

Simplify

5 x (initial length) - 15

New total length of all five pieces of wood:

5 x (initial length) - 15

Hence the required expression is 5 x (initial length) - 15.

We can start solving this problem by using a system of equations. Let x be the selling price of a card and y be the selling price of a photo frame.

From the information given, we know that on the first day:

3x + 9y = 75 (1)

And on the second day:

8x + 5y = 67 (2)

Now we have two equations with two variables. To find the value of x and y, we can use either substitution or elimination method.

One possible way to solve for x and y is to use substitution method:

Solve equation (1) for x in terms of y:

x = (75 - 9y) / 3

Substitute this expression into equation (2) to eliminate x:

8((75 - 9y) / 3) + 5y = 67

Solving this equation for y:

y = 3

Now we can substitute this value of y back into equation (1) or (2) to find the value of x:

3x + 9(3) = 75

3x = 48

x = 16

So the selling price of a card is $16 and the selling price of a photo frame is $3.

Answer:

Photo frame = $7

Card = $4

Step-by-step explanation:

Define the variables:

Given information:

Create a system of linear equations using the given information and defined variables:

[tex]\begin{cases}3c + 9p = 75\\ 8c + 5p = 67\end{cases}[/tex]

Rearrange the first equation to isolate c:

[tex]\implies 3c+9p=75[/tex]

[tex]\implies 3(c+3p)=75[/tex]

[tex]\implies \dfrac{3(c+3p)}{3}=\dfrac{75}{3}[/tex]

[tex]\implies c+3p=25[/tex]

[tex]\implies c+3p-3p=25-3p[/tex]

[tex]\implies c=25-3p[/tex]

Substitute the expression for c into the second equation and solve for p:

[tex]\implies 8c+5p=67[/tex]

[tex]\implies 8(25-3p)+5p=67[/tex]

[tex]\implies 200-24p+5p=67[/tex]

[tex]\implies 200-19p=67[/tex]

[tex]\implies 200-19p-200=67-200[/tex]

[tex]\implies -19p=-133[/tex]

[tex]\implies \dfrac{-19p}{-19}=\dfrac{-133}{-19}[/tex]

[tex]\implies p=7[/tex]

Therefore, the selling price of a handmade photo frame was $7.

Substitute the found value of p into the expression for c and solve for c:

[tex]\implies c=25-3p[/tex]

[tex]\implies c=25-3(7)[/tex]

[tex]\implies c=25-21[/tex]

[tex]\implies c=4[/tex]

Therefore, the selling price of a handmade card was $4.

An autonomous first order ordinary differential equation is any equation of the form: dy/dt = f(y).

1. Stable: The equilibrium solution y(t) = c is stable if all solutions with initial conditions y0 ‘near’

y = c approach c as t → ∞.

2. Unstable: The equilibrium solution y(t) = c is unstable if all solutions with initial conditions y0 ‘near’ y = c do NOT approach c as t → ∞.

3. Semi-stable: The equilibrium solution y(t) = c is semistable if initial conditions y0 on one side of c lead to solutions y(t) that approach c as t → ∞, while initial conditions y0 on the other side of c do NOT approach c.

Find the equilibrium points for the differential equation (1) and determine whether each is asymptotically stable, semistable, or unstable.

The graph of y0 as a function of y, and the phase line. (It’s important that α is positive – if it were negative, we’d have very different behavior).

We can see that there are two equilibrium solutions: y = 0, which is unstable, and y = 1, which is stable.

The solution to the system of equations is (7.5, 1)

From the question, we have the following parameters that can be used in our computation:

2x−3y=12

−12y+8x=48

divide the first equation by 2

So, we have

x - 1.5y = 6

This gives

x = 6y + 1.5

By substitution, the second equation becomes

-12y + 8 (6y + 1.5) = 48

So, we have

-12y + 48y + 12 = 48

Evaluate

36y = 36

Divide by 36

y = 1

So, we have

Answer:

To solve this problem we can use the formula for future value of an investment, which is:

FV = PV(1+r)^t

Where PV is the present value, r is the interest rate, t is the number of years, and FV is the future value.

In this case, we know that PV = $4,900, r = 3% = 0.03, and FV = $5,920.

So we can rearrange the formula to solve for t:

t = log(FV/PV) / log(1+r)

t = log($5,920 / $4,900) / log(1+ 0.03)

t ≈ 10.3 years

Therefore, it would take approximately 10.3 years for the account to reach $5,920.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The coordinate points for cups of flour, x and loaves of bread y is given in the table.

The slope-intercept form of an equation is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

(3 - 2)/(9 - 6)

1/3

So, the slope point is obtained as m = 1/3.

The equation becomes - y =1/3 x + b

To find the value of b substitute the values of x and y in the equation -

2 = 1/3(6) + b

2 = 2 + b

b = 2 - 2

b = 0

So, the value for b is 0.

Now, the equation becomes -

y = 1/3x + 0

y = 1/3x

The graph is plotted for the equation.

Therefore, the equation is y = 1/3x.

P(A ∩ B ∩ C ∩ D) = 2

The total number of elements are:

P (A U B U C U D) = P(A) + P(B) + P(C) + P(D) - P(A ∩ B) - P(A ∩ C) - P(A ∩ D)- P(B ∩ C) - P(B ∩ D) - P(C ∩ D) + P(A ∩ B ∩ C) + P(A ∩ B ∩ D) + P(A ∩ C ∩ D) + P(B ∩ C ∩ D) - P(A ∩ B ∩ C ∩ D).

n = 20

μ = (0.0395 + 0.0443+ 0.0450 + ... + 0.0550 + 0.0571)/20

μ = 0.9878/20

μ = 0.0494

(b) Variance = sum of squared deviations from the mean divided by n-1

s² = {(x1-μ)² + (x2-μ)² + .... (xn - μ)²)/(n-1)

s² = {(0.0395-0.0494)² + (0.0443-0.0494)² + .... +(0.0571-0.0494)²}/19

s² = 0.000016

(b) The minimum is 0.0395 and the maximum is 0.0571.

since the number of data is even, the median will be the average of two middle values.

M = Q2 = (0.0496+0.0499)/2 = 0.04975

Now, the first quartile is the median of the data values below the median

so Q1 = (0.0470+0.0485)/2 = 0.04775

And third quartile will be the median of the data values above the median

Q3 = (0.0504+0.0516)/2 = 0.0510

(c) Since we know that the number of data values is even, the median will be the average of the two middle values of the data set

so M = (0.0496+0.0499)/2

or M = 0.04975

What is an inequality?

In algebra, the inequality symbol is used to show how two expressions are related in an inequality assertion. Uneven expressions can be seen on both sides of a sign of inequality.

We are given a graph on which two inequalities are plotted

So, first, we will have to frame the equations from the points.

For the blue line, we have points (0,-3) and (-1.5,0)

So, using slope-intercept form, we get the equation as

y + 2x ≥ -3

For the red line, we have points (-1,-2) and (0,2)

So, using slope-intercept form, we get the equation as

y - 4x ≥ 2

For finding the solution, we will subtract both the equations

On subtracting, we get

⇒(y+2x) - (y-4x) = -3 - 2

⇒y+2x - y + 4x = -5

⇒6x = -5

⇒x = -0.83

Substituting this value in the equation, we get

⇒y+2(-0.83) = -3

⇒y-1.66 = -3

Part A: The number of survey respondents that do not like hamburgers is 205 - 81 = 124.

Of these 124 respondents, 38 do not like burritos as well, so the percentage of respondents that do not like both hamburgers and burritos is 38 / 124 * 100% = 30.6%.

Part B: The marginal relative frequency of all customers who like hamburgers is 81 / (81 + 205) = 28.2%.

Part C: The conditional relative frequency of customers that like burritos given they like hamburgers is 49 / 81 = 60.5%.

The conditional relative frequency of customers that do not like burritos given they like hamburgers is 32 / 81 = 39.5%.

The conditional relative frequency of customers that like hamburgers given they like burritos is 49 / 141 = 34.8%.
