10. The perimeter of the table shown is 16 feet. Write an equation in
the form px + q=r to solve for x.

The required values of x and y are x = 2 and y = 11.

We have been given that parallelogram PQRS which has:

PT = ​y, TR = 5x+​1, QT = 2​y, TS = 6x+10

We know that the diagonals of a parallelogram bisect each other.

So, PT = TR and QT = TS

Substitute the values and we have a system of equations:

y = 5x + ​1    ....(i)

2y = 6x + 10 ....(ii)

Substitute the value of the equation y = 5x + ​1 in equation (ii), and solve for x

2(5x + ​1) = 6x + 10

10x + 2 = 6x + 10

10x - 6x = 10 - 2

4x = 8

x = 8/4

x = 2

Substitute the value of x = 2 in equation (i), and solve for y

y = 5(2) + ​1

y = 10 + 1

y = 11

Therefore, the required values of x and y are x = 2 and y = 11.

To evaluate the integral, you will need to define the limits of integration and use appropriate coordinate systems for the given area.

And the area is given as   [tex]I_{xy} =\int \limits \int \limits {(y^2 - x^2)} \,dm[/tex]

What is direct integration?

Direct integration is a method of finding the moment of inertia of a body or a region about a given axis by directly integrating the product of the mass of each infinitesimal element of the body or region and the square of its distance from the axis.

To determine the product of inertia of a given area with respect to the x and y axes, you will need to first define the area and its mass distribution. Then, you can use the following formula for the product of inertia:

[tex]I_{xy} =\int \limits \int \limits {(y^2 - x^2)} \,dm[/tex]

Where Ixy is the product of inertia, y is the distance from the y-axis, x is the distance from the x-axis, and dm is the mass of an infinitesimal element of the area.

Hence, To evaluate this integral, you will need to define the limits of integration and use appropriate coordinate systems for the given area.

The population of the city after eight years is 35,125,731,743

Population growth is the increase in the number of people in a population or dispersed group. The expression P(t) = P(o)(1+r)^t can be used to determine the growth rate of a population.

Where P(t) is the population at a particular time

P(o) is the initial population , t is the time and r is the growth rate.

Here the growth rate has been given, but we are to find p(t).

P(t) = 330,000(1+3.25)⁸

P(t) = 330,000(4.25)⁸

P(t) = 330,000× 106441.61

P(t) = 35,125,731,743( nearest billion)

Using mathematical operations, we can say that total of 69 ft of lights is needed to cover all 8 windows.

An operation is a function in mathematics that converts zero or more input values into a clearly defined output value.

The operation's arity is influenced by the number of operands.

The rules that define the order in which we should solve an expression involving many procedures are known as the operation order.

PEMDAS stands for Parentheses, Exponentiation, Multiplication, Division, and Addition and Subtraction (from left to right).

So, we know the dimensions of the window:

3 ½ feet wide and 5 feet long.

And there is a total of 8 windows.

The perimeter of the rectangle: 2(l+w)

Now, the feet of light needed will be:

2(l+w) * 8

2(3 ½+5) * 8

2(7/2+5) * 8

7+5 * 8

12 * 8

96 ft

Therefore, using mathematical operations, we can say that total of 69 ft of lights is needed to cover all 8 windows.

By using determinant, it can be calculated that-

det(C) = 8

det(D) = 9

What is a determinant?

Determinant of a square matrix is equal to the product of the elements of a square matrix and their cofactors.

Here,

det(A) = -8

The matrix C is obtained from A by swapping the second and third rows

We know if the rows and columns of a matrix are swapped then the value of the determinant of the new matrix changes in sign only

So det(C) = 8

Now,

det(A) = 9

We know that the value of determinant remain unchanged on adding any combination row or column

Matrix D is obtained from A by adding 2 times the fourth row to the first

det(D) = 9

After solving the equation, we can conclude that Callie should rent the bicycle for a maximum of 3 hours.

The equals sign is indeed a symbol used in mathematical formulas to denote the equality of two reactions.

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

For example, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

So, according to the given information, form the equation as follows:

12x + 10 = 45

Where x is the number of hours Callie rents the cycle.

Now, calculate for x as follows:

12x + 10 = 45

12x = 45 - 10

12x = 35

x = 35/12

x = 2.91

Answer:

The future value of an investment is calculated by using the formula:

$FV = PV(1 + r/n)^{nt}$

where $FV$ is the future value, $PV$ is the present value (the initial investment), $r$ is the interest rate, $n$ is the number of times the interest is compounded per year, and $t$ is the number of years the investment is held.

In this case, we have $PV = 1743$, $r = 5.45% = 0.0545$, $n = 2$, and $t = 2$. Plugging these values into the formula, we get:

$FV = 1743(1 + 0.0545/2)^{2 \cdot 2} = 1743(1 + 0.0273)^{4}$

Now we can calculate the future value by raising $1 + 0.0273$ to the power of 4:

$FV = 1743(1.0273)^{4} \approx \boxed{1956}$

Note that we rounded the result to the nearest cent.

The ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane is known as slope of line.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph, we can take two points (4, 3) and (8, 6) to find the slope.

What is system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.

Let

Price of shirts = x

Price of slacks = y

Price of sports = z

From the given information,

3x + y = $13.46         ..(1)

7x + 3y + z = $43.39         ..(2)

5x + 2z = $28.43        ..(3)

From equation (1), y = 13.46 - 3x

From equation (3),  z = (28.43 - 5x) / 2

Plug the value of x and z in equation (2)

7x + 3(13.46 - 3x) +(28.43 - 5x)/2 = 43.39

7x + 40.38 - 9x + 14.22 - 2.5x = 43.39

-4.5x +54.6 = 43.39

4.5x = 54.6 - 43.39

4.5x = 11.21

x = 2.49

Plug x = 2.49 in equation (1)

3(2.49) + y = 13.46

2.47 + y = 13.46

y = 5.99

Plug x = 2.49 in equation (3),

5(2.49) + 2z = 28.43

12.45 + 2z = 28.43

2z = 15.98

z = 7.99
