I don’t understand. Please Help!!!

Answer:

I believe it says the vertex at Y is moved to T:

the angle of each side changes by 360 / 8 = 45 at each vertex

If 3 vertices separate Y and T the the total rotation would be

3 * 45 = 135 deg

The octagon rotated 135 degree.

An octagon is a polygon with eight sides.

The total angle at the center is 360 degree and for a regular octagon, the angle made by each side is equal to 360/8 = 45 degree.

The octagon STUVWXYZ is rotated clockwise such that, the vertex Y moves to T.

Movement of Y to T is moving 3 steps clockwise

= 45* 3

= 135 degree

The constraint x₁A + x₂A = 250 in an LP transportation problem means that supply nodes 1 and 2 must produce exactly 250 units in total to meet the demand of demand node A.

To understand this constraint, let's break it down:

x₁A represents the units shipped from supply node 1 to demand node A.

x₂A represents the units shipped from supply node 2 to demand node A.

The equation x₁A + x₂A = 250 states that the sum of the units shipped from supply nodes 1 and 2 to demand node A must equal 250. In other words, the total supply from nodes 1 and 2 should meet the demand of 250 units from node A.

Therefore, the correct interpretation of the constraint is that demand node A has a requirement of 250 units from supply nodes 1 and 2.

Answer:

B.

Step-by-step explanation:

m is the driving number in this system of numbers. whatever its value, all the others need to adjust to it.

c depends fully on m. if and when m increases, then also c has to increase.

Check the picture below.

the function is x^2-9, so all you have to do is replace x with a number. for example, 2.

so 2^2-9 is -5. the plot would be 2, -5. basically, plug in a number to be the x coord, and whatever number you get will be your y coord.

after you graph a few plots (doing the same thing above), draw a line through all of them.

if the line goes up towards the right top corner, it's increasing. if it goes down the right bottom corner, it's decreasing.

So the dimensions of the box are:

Length: 20m

Width: 10m

Height: 10m

We can use the information provided in the problem to set up a system of equations. Let H be the height, L be the length, and W be the width.

From the problem, we know:

L = 2H (the length is twice the height)

W = L - 10 (the width is 10 meters less than the length)

2HW + 2LW + 2LH = 10WH (the surface area is 10 times the width times the height)

We can substitute the first and second equations into the third one to obtain:

2H(2H-10) + 2(2H)(2H-10) + 2(2H)(2H) = 10H(2H-10)

Solving this equation we get H = 10m

With this value we can solve for the other dimensions:

L = 2H = 2 * 10 = 20m

W = L - 10 = 20 - 10 = 10m

So the dimensions of the box are:

Length: 20m

The expression that will give the distance between points is option D i.e. √(2 - 4)² + (3 + 3)². The solution has been obtained by using distance formula.

What is the distance formula?

The distance between two locations on a coordinate plane can be calculated using the distance formula. The distance equation is written as d = √(x₂ - x₁)² + (y₂ - y₁)².

We are given two points as (2,3) and (4,-3).

So, x₁ = 2, y₁ = 3, x₂ = 4, y₂ = -3

Now, substituting these values in the distance formula, we get

d = √(2 - 4)² + (3 + 3)²

Hence, the expression that will give the distance between points is option D.

The midline equation of the function is y = 2.95.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Midline is the horizontal line that passes in the middle between the graph's maximum and minimum points.

Now,

Maximum point = (11.4, 11.4)

Minimum point = (-5.5, -5.5)

A horizontal line means the y-coordinates.

So,

Midline = (11.4 + (-5.5)) / 2 = 2.95

Answer:

Measure of angle B = 64.147°

Step-by-step explanation:

Because we don't know whether this is a right triangle, we can find the measure of angle B using the Law of cosines

The law relates the lengths of the sides of a triangle to the cosine of one of its angles and has three forms

a^2 = b^2 + c^2 - 2bc * cos(A)

b^2 = a^2 + c^2 - 2ac * cos(B)

c^2 = b^2 + a^2 - 2ba * cos(C)

In the triangle, c is 11 units, b is 10 units, and angle A is 34°.  

Step 1:  Find the length of a:

Because the Law of Cosines requires all three sides, we must find side a's length.  

We can use the first formula for the Law of Cosines and plug in 11 for c, 10 for b, and 34 for A, allowing us to solve for a:

1.1 Plug in values and simplify:

a^2 = 10^2 + 11^2 - 2(10)(11) * cos(34)

a^2 = 100 + 121 - 220 * cos(34)

a^2 = 38.61173404

1.2 Take the square root of both sides to solve for A

√(a^2) = √(38.61173404)

a = 6.213834085

Not rounding at this intermediate step in the problem will allow us to find the exact measure of angle B

Thus, a = 6.213834085 units.

Step 2:  Find the measure of angle B:

Now we can use the Law of Cosines' second formula and plug in 11 for c, 10 for b, and 6.213834085 for a, allowing us to solve for B.

2.1 Plug in values and simplify

10^2 = 11^2 + 6.213834085^2 - 2(11)(6.213834085) * cos(B)

100 = 121 + 38.61173404 - 136.7043499 * cos(B)

100 = 159.611734 - 136.7043499 * cos(B)

2.2 Subtract 159.611734 from both sides:

(100 = 159.611734 - 136.7043499 * cos(B)) - 159.611734

-59.61173404 = -136.7043499 * cos(B)

2.3 Divide both sides by -136.7043499:

(-59.61173404 = -136.7043499 * cos(B)) / -136.7043499

0.4360631836 = cos(B)

2.4 Use cosine inverse to find the measure of angle B:

cos^-1 (0.4360631836) = B

64.14703487 = B

64.147 = B

Thus, the measure of angle B (rounded to the nearest thousandth) is 64.147°.

Combining negatively correlated assets with the same expected return results in a portfolio with the same level of expected return but a lower level of risk.

When assets have a negative correlation, their returns tend to move in opposite directions. By combining these assets in a portfolio, their negative correlation offsets each other's risks to some extent. As a result, the overall risk of the portfolio is reduced.

However, the expected return of the portfolio remains the same as the individual assets, assuming they have the same expected return. This is because the negative correlation does not affect the average return of the assets, only their volatility. The diversification benefits provided by negatively correlated assets help to reduce the overall risk of the portfolio, making it less volatile than the individual assets.

Therefore, combining negatively correlated assets with the same expected return results in a portfolio with the same level of expected return but a lower level of risk. This is a desirable outcome for investors as it allows them to achieve a certain level of return while minimizing the overall risk in their investment portfolio.

Answer: x = -26 && y = -3

Step-by-step explanation: Please see attachment

Answer:

x = - 26 , y = - 3

Step-by-step explanation:

- \(\frac{4}{5}\) x + 7y = - \(\frac{1}{5}\) ( multiply through by 5 to clear the fractions )

- 4x + 35y = - 1 → (1)

\(\frac{1}{2}\) x - \(\frac{1}{3}\) y = - 12 ( multiply through by 6 to clear the fractions )

3x - 2y = - 72 → (2)

Multiplying (1) by 3 and (2) by 4 and adding will eliminate the x- term

- 12x + 105y = - 3 → (3)

12x - 8y = - 288 → (4)

Add (1) and (2) term by term to eliminate x

97y = - 291 ( divide both sides by 97 )

y = - 3

Substitute y = - 3 into (2) and solve for x

3x - 2(- 3) = - 72

3x + 6 = - 72 ( subtract 6 from both sides )

3x = - 78 ( divide both sides by 3 )

x = - 26

Then x = - 26 , y = - 3 is the solution
