The design using three equilateral triangles and two isosceles triangles is shown using the vertices.

Any triangle with three equal sides is said to be equilateral. The third side of this particular isosceles triangle is also equal. ABC has the formula AB = BC = CA. An equilateral triangle has the following qualities:

It has three equal sides. The three angles are equal. Every angle of an equilateral triangle is 60 degrees since the sum of the interior angles is 180 degrees.

It has three regular sides and is a polygon.

Regardless of which way the triangle's apex points, an isosceles triangle is one that has two equal sides. Angle determination can be done using isosceles triangles. AB Equals AC in the isosceles triangle ABC. Likewise, PQ Equals PR in the triangle PQR. The isosceles triangle's base is represented by the uneven sides BC and QR, while vertices A and P are regarded as the triangle's peaks. Among its attributes are:

There are equal sides on it. The basis angles are two equal angles that make up the object. A triangle is referred to as a right isosceles triangle when the third angle is 90 degrees.

The length of segment AB is determined as 13 units.

The distance between two points is the length of the line segment that connects the two points in a plane.

here, we have,

The length of segment AB is the distance between point A and point B, which is calculated as follows;

|AB| = √[(x₂ - x₁)² + (y₂ - y₁)²]

where;

x₁ is the x - component of point A

x₂ is the x - component of point B

y₁ is the y - component of point A

y₂ is the y- component of the point B

|AB| = √[(x₂ - x₁)² + (y₂ - y₁)²]

|AB| = √[(-5 - 7)² + (5 - 10)²]

|AB| = √[144+25]

|AB| = 13 units

Thus, the length of segment AB is the distance between point A and B.

In mathematics, differentiation is the process of determining the derivative, or rate of change, of a function. Differentiation is a technique for determining a function's derivative. Differentiation is a mathematical procedure that determines the instantaneous rate of change of a function based on one of its variables. The process of finding the derivative of dependent variable in an implicit function by differentiating each term separately

Given data ,

Let the function be represented as f ( x )

Answer:

3 millimeters

Step-by-step explanation:

The formula for finding perimeter: 2W+2L=P

W= width

L= length

P= Permiter

So just substitute the numbers in the equation

4 millimeters is the width

14 millimeters is the perimeter

So this is your equation

2*4+2L=14

8+2L=14

Subtract 8 from both sides

2L=6

Divide both sides by 2

L=3

So your length is 3 millimeters

To check:

(2*4)+(2*3)=14

8+6=14

Step-by-step explanation:

Because, your y axis travels from 34 to 22, in that case you have to take away 22 from 34 which you get 12.

The set {10,17,27} does not represent the three sides of a triangle,

Having three edges and three vertices, a triangle is a three-sided polygon. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.

Given  the sets for the triangles,

property of triangles says that,

The length of a triangle's two longest sides added together is longer than the third side.

Similarly to this, the length of the third side of a triangle third side is shorter than the difference between its two sides.

1: given sides are 10, 17, 27

according to the property sum of 10 and 17 should be greater than  27 but sum  is equal to 27,

10 + 17 = 27,

so the sides do not represent the triangle

2: sides are 9, 22, 30

here 9 + 22 > 30

the set represents the triangle.

3: sides 6, 16, 19

6 + 16 > 19

the set represents the triangle.

4: sides 4, 7, 9

4 + 7 > 9

set represents the triangle.

The required number of Barnes & Noble stores in 2009 is 725.28.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

To determine the number of Barnes & Noble stores in 2009, we need to evaluate the piecewise function for t = 2009.

Since 2009 is between the interval 6 ≤ t < 12, the number of stores is given by the first piece of the function:

y = -3.692 × x² + 65.28 × x + 437.30

put x = 9 for the year 2009

y = -3.692 × 9² + 65.28 × 9 + 437.30 = 725.28

So, there were 725.28 Barnes & Noble stores in 2009.

A linear equation is an equation in which each term has at max one degree. The table that represents a linear function is Table 1. Thus, the correct option is A.

A linear equation is an equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on a cartesian plane with axes of those variables, give a straight line.

For the table to represent a linear function, the function must have a constant slope between any two points.

For the first table, the slope between the first two points is,

m = (7-3)/(2-1) = 4

The slope between the last two points is,

m = (15-11)/(4-3)

Answer:

x = - 3.5 , y = - 5.5

Step-by-step explanation:

y = x - 2 → (1)

y = 3x + 5 → (2)

substitute y = 3x + 5 into (1)

3x + 5 = x - 2 ( subtract x from both sides )

2x + 5 = - 2 ( subtract 5 from both sides )

2x = - 7 ( divide both sides by 2 )

x = - 3.5

substitute x = - 3.5 into either of the 2 equations for y

substituting into (1)

y = x - 2 = - 3.5 - 2 = - 5.5

then x = - 3.5 and y = - 5.5

The division expression is (5x³ - 22x² - 17x + 11)/(x - 5) = 5x² + 3x -  2 + (2/(x - 5))

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

(5x³ - 22x² - 17x + 11)/(x - 5)

Using a synthetic setup, we have

x - 5 = 0

This gives

x = 5

So, the set up becomes

5 | 5   -22   -17   11

The synthetic division is then carried out as follows

5 | 5   -22   -17   11

           25   15   -10

     5     3     -2   1

So, we have

Quotient = 5   3   -2

When the principal is $ 34000, the rate is 7.5%, and the time period is 100 days, the simple interest is $ 698.63.

Increase the investment by the lending rates, the length of time, and other factors to arrive at simple interest. Simple return = money + interest + hours is the selling formula. This method makes it easiest to calculate interest. The most conventional technique to figure out interest is as a portion of the principal sum. He will indeed pay his share of the 100percent interest, for example, if he buys $100 from just a friend and offers to pay it back with 5% interest. $100 (0.05) = $5. When you borrow more money, you should pay interest, then when you give it out, you must charge interest. Interest is often determined as an extra component of the loan total. The interest on the loan is this percentage.

given

r = R/100 = 7.5%/100 = 0.075 per year,

putting time into years for simplicity,

100 days ÷ 365 days/year = 0.273973 years,

then, solving our equation

I = 34000 × 0.075 × 0.273973 = 698.63115

I = $ 698.63

When the principal is $ 34000, the rate is 7.5%, and the time period is 100 days, the simple interest is $ 698.63.
