Explanation:

The equation y - b = m(x - a) is a mathematical formula that describes the relationship between the x and y coordinates of a point on a line. The equation is called "point-slope form" because it uses the coordinates of a point on the line (point a) and the slope of the line (m) to describe the line.

The equation has three parts: y, b, and m(x - a).

The y part of the equation represents the y-coordinate of a point on the line. This value can change depending on the x-coordinate of the point.

The b part of the equation is the y-coordinate of a known point on the line. This value is fixed and does not change.

The m(x - a) part of the equation represents the slope of the line and the x-coordinate of the known point on the line. The slope is represented by m, and the x-coordinate of the known point is represented by a.

To use the equation to find the y-coordinate of a point on the line, you first need to know the x-coordinate of the point and the values of b, m, and a. Then, you can substitute these values into the equation and solve for y.

For example, if the x-coordinate of a point on the line is 5, the y-coordinate of a known point on the line is 2, the slope of the line is 3, and the x-coordinate of the known point is 1, then the y-coordinate of the point can be calculated as follows:

y - 2 = 3(x - 1)

y = 3x - 3 + 2

y = 3(5) - 3 + 2

y = 15 - 3 + 2

y = 14

Therefore, the y-coordinate of the point with x-coordinate 5 is 14.

In summary, the equation y - b = m(x - a) is a mathematical formula that describes the relationship between the x and y coordinates of a point on a line. The equation uses the coordinates of a known point on the line and the slope of the line to describe the line, and you can use it to find the y-coordinate of a point on the line if you know the x-coordinate of the point and the values of b, m, and a.

The best estimate to get the  total number of times to get a "3" will be 24 times.

This is an expression that simply refers to mathematical statements that have at least two terms which are related by an operator and contain either numbers, variables

In this case, Jimm tossed a die several times and he got the number "3" on 8 of the tosses.

Therefore, when there are 64 tosses, the estimate will be:

= 3/8 × 64

= 3 × 8

Option a) The similar triangles are ⇒ ΔADE ≅ ΔABC

Option b) ∠ADE = ∠ABC

According to the figure given in the question,

We can observe that there are two right-angled triangles present and we have to derive the similarities between them

Let one triangle be = ΔADE

Another triangle be = ΔABC

Let us consider the angle arc at point A,

We can conclude that ⇒ ∠BAC = ∠DAE ( according to the property of similar angles )

⇒ ∠ADE = ∠ABC ( by the similar 90° angles )

and both angles are making a total of 180°

So, from the above expressions, we can say that,

⇒ ∠AED = 180° - ∠A - ∠ABC

⇒ ∠ACB = 180° - ∠A - ∠ABC

Hence, ∠AED = ACB ⇒ ΔADE ≅ ΔABC

Therefore,

The hypotenuses(x) of the triangle whose legs are 12 cm and 16 cm is 20 cm.

As we know that in a right angled triangle there are base, perpendicular and hypotenuse. a hypotenuse is the longest side of a right triangle. In other words, the side opposite to the right angle is called the hypotenuse.

Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

By Pythagoras theorem, hypotenuse (x)  = √(a² + b²)

                                                                        =  √(16² + 12²)

The statements which must be true is statement 4 which is  :-

  Point a is not necessarily the center of the circle that passes through points e, f, and g or the center of the circle that passes through points x, y, and z.

3 points uniquely define a circle. so points e,f and g uniquely defines a circle C1 and point x,y and z uniquely defines a circle C2.

The below figure shows the condition that 2 different circle C1 and C2  can have same center , point a and this conditon occurs when they are concentric circle so statement 1,2 is false as in these statement it is told that point a can be center of only one circle but point a can be center of more than 1 circles.

and it is also possible that these 2 different cirlce C1 and C2 can have different center which is 2 different circle ,so statement 3 is also false.

Answer:

0.262 hectares

Step-by-step explanation:

To find the size of each property, you need to divide the total area of the land by the number of properties. In this case, the total area of the land is 1.31 hectares, and it is being divided into 5 properties, so the size of each property is:

Property size = 1.31 hectares / 5 properties = 0.262 hectares/property

Therefore, each property will be 0.262 hectares in size.

the percent increase in enrollment, and round to the nearest percent is 40%

Given that number of students enrolled in 2010= 2000

Given that number of students enrolled in 2018 = 2800

2800is more than 2000 so that means number of students enrollment is increasing.

increase = 2800-2000= 800

Percent increase is given by formula:

% increase = 800/2000*100= 40

A polynomial function is a mathematical function defined by an expression that is a sum of terms, each of which is a product of a constant and a non-negative integer power of a variable. The term "polynomial" comes from the Greek word "polys," which means "many," and "nomos," which means "terms." Polynomial functions are distinguished by the degree of their highest-degree term, which is the largest exponent of the variable. For example, the polynomial function f(x) = x3 + 2x2 + x - 1 has a degree of 3 because the highest-degree term is x3.

Out of the four given options, only the functions f(x) = x3 + 2x2 + x - 1 and f(x) = x3 +1 are polynomial functions. The other two options, y = -2x3 + 5x – 4 - 4 and f(x) = V2x3 + 5, are not polynomial functions because they contain terms that are not of the form "constant times a non-negative integer power of a variable." The function y = -2x3 + 5x – 4 - 4 contains the term -4, which is not a product of a constant and a non-negative integer power of a variable, and the function f(x) = V2x3 + 5 contains the term V2x3, which is not a product of a constant and a non-negative integer power of a variable. Therefore, the correct answer is A and D.

The three rational numbers are 7, 2 and 15

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

First Number= x

Second Number= x- 5

Third Number = 2x+ 1

so, the product of the three number be 210

x(x-5 )(2x+ 1)= 210

(x² -5x )(2x+ 1)= 210

2x³ + x² - 10x² - 5x= 210

2x³ -9x² -5x -210=0

On solving the equation we get only one real value 7 and other values are imaginary.
