A vector space is an abstract mathematical concept that is used to describe a collection of elements, known as vectors.

Vector is a mathematical object that has both magnitude and direction. It can be represented graphically by a line segment with a starting point and an endpoint. Vectors are used in physics, engineering, and mathematics to represent physical quantities such as force, velocity, and acceleration. They can also be used to represent geometric figures such as lines, points, and planes. Vectors are important in many applications, such as navigation, graphics, and robotics.

It is an important concept in linear algebra, and is used to describe the behavior of linear equations and systems.

A vector space is made up of a set of vectors, which can be seen as elements of the space. Each vector is a combination of scalar numbers, called components, and the space is made up of all possible combinations of these components. The components can be real numbers, complex numbers, or even functions.

The vector space is defined by certain operations, called vector addition and scalar multiplication. Vector addition is the process of adding two vectors together, and scalar multiplication is a process of multiplying a vector by a scalar number. Using these operations, the vector space can be used to solve linear equations and systems of equations.

The vector space is also used to describe the geometry of the space. It is used to describe dimensions, angles, and distances between vectors. It is also used to describe shapes and objects within the space, and to describe how they interact with each other.

Finally, the vector space is used to represent linear transformations, which are important in physics and engineering. A linear transformation is a process of mapping a vector to another vector, and is used to describe the behavior of physical systems. This can be used to solve complicated equations and systems of equations.

The crates 1 has 9 dozens of eggs and the crate 2 has 12 dozens

They are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, division among others.

According to the data problem, lets call:

Dozens of crate 1 = x

Dozens of crate 2 = y

The crate 1 cost $1.50/ dozen so: 1.50x

The crate 2 cost $2.00/ dozen so: 2y

He bought 3 dozens more than the first crate: y = 3+x

The number of eggs bought was: x + y

The number of eggs bought was: x + 3+x

The number of eggs bought was: 2x + 3

He spend = 1.50x + 2y

He spend = 1.50x + 2(3+x)

He spend = 1.50x + 6 + 2x

He spend = 3.50x + 6

The sale was = 2.50*(2x+3)

The sale was = 5x + 7.50

Profit = sale - spend

15 = (5x + 7.50) - (3.50x + 6)

15 = 5x + 7.50 - 3.50x - 6

15= 1.5x + 1.5

Clearing the variable we have:

1.5x = 15 - 1.5

1.5x = 13.5

x = 13.5/1.5

x=9

Crate 1 = 9 dozens

Crate 2 = 3+9 = 12 dozens

The solution to the system of equations is (5, -3). To solve the system of equations 3x + 2y = 9 and 2x + 3y = 6, we can use the method of substitution.

We can solve one of the equations for one of the variables in terms of the other variable. For example, we can solve the second equation for x to get x = (6 - 3y)/2. Then, we can substitute this expression for x into the first equation and solve for y: 3(6 - 3y)/2 + 2y = 9

Simplifying this equation, we get: 9 - 9y + 4y = 18. Solving for y, we get: y = -3

Now that we have the value of y, we can substitute it into one of the original equations to solve for x. Using the first equation, we get: 3x + 2(-3) = 9

Simplifying this equation, we get: 3x = 15. Solving for x, we get: x = 5

Therefore, the solution to the system of equations is (5, -3).

a) The convolution of cos(2t)u(t) by direct computation of the integral is given by:

cos(2t) * u(t) = (1/2)sin(2t)u(t) + (1/4)δ(t)

where sin(2t) represents the sine wave with frequency 2, u(t) is the unit step function, and δ(t) is the Dirac delta function.

b) The convolution of cos(2t)u(t) by computing in the s-domain involves taking the Laplace transform of both functions, multiplying their Laplace transforms, and then applying the inverse Laplace transform. The result is the same as in part (a):

Amongst the options circle shape from the Clade Race would be considered plesiomorphic.

A primitive or ancestral character state is called plesiomorphy or known as a plesiomorphic character), and a shared plesiomorphy is called a symplesiomorphy. For example, let us take an example of hair. It is a unique mammalian character that evolved with the evolution of mammals.

The term apomorphy means a specialized or derived character state which is plesiomorphy. It refers to a primitive or ancestral trait. An same as autapomorphy, it is a derived trait that is unique to one group, while a same as synapomorphy is a derived trait shared by two or more groups.

9/15=3/X

9X=15×3

X=15×3/9=5

The value of x is 5 units.

We need to solve for x, from the given figure.

Two triangles are similar if their corresponding angles are congruent and corresponding sides are proportional.

Now, in ΔABC and ΔADE

∠B=∠D=90°

∠EAD=∠CAB (common angles)

So, from AA similarity ABC~ADE

Step-by-step explanation:

Ok, so let us assume that AB = x, from here we know the length of AC is xsqrt(2).

So,

area of ABCD = area of ACEG = x^2

From here, AG = x^2/xsqrt(2), which equals xsqrt(2)/2

Finally, AC to CE = xsqrt(2) : xsqrt(2)/2

The weighted-average unit contribution margin is $46.20.

The weighted-average unit contribution margin can be calculated by multiplying the unit contribution margin of each model by its respective sales mix percentage, and then summing up the results.

To find the weighted-average unit contribution margin, we first calculate the unit contribution margin for each model by subtracting the unit variable costs from the selling price:

For Model A12:

Unit contribution margin = Selling price - Unit variable cost

                     = $60 - $42

                     = $18

For Model B22:

Unit contribution margin = Selling price - Unit variable cost

                     = $120 - $84

                     = $36

For Model C124:

Unit contribution margin = Selling price - Unit variable cost

                     = $480 - $360

                     = $120

Next, we multiply each unit contribution margin by its respective sales mix percentage:

Weighted contribution margin for Model A12 = 60% * $18 = $10.80

Weighted contribution margin for Model B22 = 15% * $36 = $5.40

Weighted contribution margin for Model C124 = 25% * $120 = $30.00

Finally, we sum up the weighted contribution margins:

Weighted-average unit contribution margin = $10.80 + $5.40 + $30.00 = $46.20. Therefore, the weighted-average unit contribution margin is $46.20.

The area of the field is:

A = (x + 20)y

The length of fence needed is:

x + y + x + 20

(remember that 20 ft are not needed because the building, and y ft are not needed because the river)

We have 1000 ft of fencing, then:

1000 = x + y + x + 20

1000 - 20 = 2x + y

980 = 2x + y

Isolating y from the preceding equation:

y = 980 - 2x

Substituting this into the area equation:

A = (x + 20)(980 - 2x)

Distributing:

At the maximum, the derivative of A with respect to x is zero, then:

Recalling the equation of y and substituting this result:

y = 980 - 2x

y = 980 - 2*235

y = 510

The dimensions are:

length: 255 ft (on the side without the building)

width: 510 ft

Answer:

See below

Step-by-step explanation:

Long side = x

         Other long side = x - 20

short side = y  

Area enclosed = xy

x  +   x -20   + y    = 1000    or y = 1020 -2x    <=====sub into first equation

area = x * ( 1020-2x) =  -2x^2 + 1020x  

         this is a dome shaped parabola  

           max will occur at x = -b/2a = - 1020/ (2 * -2) = 255 ft

  then y =   1020 -2x = 510 ft

(area = xy = 130 050 ft^2 )
