A 4 polygon is a two-dimensional shape with four sides and four angles.

Polygon is a closed figure in a plane made up of straight lines or curved lines that intersect in pairs. A polygon has at least three sides and angles. The sides can be of any length and the angles can be of any measure. Polygons are classified according to the number of sides they have, such as triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), etc. Polygons are used in many fields, from mathematics to engineering.

It is a type of quadrilateral, which is a polygon with four sides. Examples of 4 polygons include squares, rectangles, rhombuses, and trapezoids. All 4 polygons have four sides of equal length, and all their interior angles add up to 360 degrees.

After using the Pythagorean theorem, the hypotenuse of the length x is 14.14 cm

In this case, we are given that:

The isosceles right triangle has two legs with length 10 cm

Let’s assume leg 1 as “a” = 10 cm, and leg 2 as “b” = 10 cm

The length of hypotenuse is “c”

To find the value of the hypotenuse or the longest side of a right triangle, we can use Pythagorean theorem:

a² + b² = c²

10² + 10² = c²

200 = c²

c = √200 =  14.14 cm

Therefore, the length of the hypotenuse would be 14.14 cm

An element of one non-empty set and an element of another non-empty set are said to have a special relationship when they are connected by a function in mathematics.

An assignment of an element from set Y to each element of set X, where set X is the domain and set Y is the codomain, is what is meant when a function is applied from a set X to a set Y.

We have given that f(t) is given by the Sales of $10,000 increase by 65% each year, i.e.

As sales of $10,000 increase by 65% each year.

The situation is represented by an exponential growth function.

The initial amount a = 10,000

The rate of growth r = 65% = 0.65

Therefore, the function will be:

                                                   t = a(1 + r)ⁿ

Answer:

Isosceles triangle

Step-by-step explanation:

Isosceles triangle has more than 90 but less than 180, which means Isosceles triangle is equal to 120.

The point represents the number of small gloves is 16 and the number of large gloves is 2.

According to the mathematical definition of inequality, neither side is equal. When a relationship leads to a non-equal comparison between two expressions or numbers, it is known as an inequality in mathematics. The equal sign "=" in this statement can be replaced with any of the inequality symbols, such as greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), or not equal to (≠).

Given  Wanda sews small and large gloves,

time for small gloves = 45 minutes

time for large gloves = 120 minutes

total time = 16 hours = 960 minutes

let x be the number of small gloves and y be the number of large gloves,

inequality equation is 45x + 90y ≤ 960

and the cost of small gloves = $2

cost of large  gloves = $4

total amount = $40

equation 2x + 4y ≤ 40

let us assume the system of inequality in form of a linear equation,

45x + 90y = 960

2x + 4y = 40

by solving the equations

the equation is written as

x = 20 - y

45(20 -y) + 90y = 960

y = 2

and x = 16

so the minimum values for x and y are 16 and 2 to maximize the profit Wanda should not decrease the production of small gloves from 16 and large gloves to 2.

Hence the point of maximization is (16, 2).

Two steps in solving the inequality: simplify the algebraic expressions by combining like terms and isolating the target variable, then applying the mathematic operators.

-  Simplify the expression by: open the parentheses of algebraic expression, combine the terms like, and isolate the target variable.

- Use mathematic operators such as: addition, subtraction, multiplication, and division. All mathematic operations must be done on both sides. Addition and subtraction do not change the inequality. Multiplication and division with positive numbers will not change the inequality.

Multiplication and division with negative numbers will change the sign of the inequality.

Example:

Solve the inequality: 3x + 2 < 5x - 8

Step one: Subtract both sides with 5x and 2, this operation does not change the inequality sign

3x + 2 - 5x - 2 < 5x - 8 - 5x - 2

-2x < -10

Step two: Divide both sides with (-2). Since we divide with negative numbers, flip the inequality sign.

-2x/(-2) > -10/(-2)

x > 5

Hence, the solution is x> 5

Answer:

B.) An isosceles triangle has at least two sides with equal measures.

Step-by-step explanation:

There are two equal sides and two equal angles in an isosceles triangle. There should be at least 2 equal sides for an Isosceles triangle. This means, even an equilateral triangle is an Isosceles triangle. In this case, at least two equal sides are 8 inches each. This is why the correct answer is 'Yes; an isosceles triangle has at least two sides that have equal measures.'

Therefore , the solution of the given problem of triangle comes out to be x = 32.376 side of the hypotunse length.

Since a triangle has four or even more sections, it is a polygon. It has an easy geometric form. Triangle ABC refers to a square with angles A, B, & C. A singular plane and square are produced by Euclidean geometry whenever the sides are still not collinear. A triangle is a polygon if it has 3 components and three corners. Where a triangle's three sides come together are known as the corners. A triangle's angles add up to 180 degrees.

Here,

Given:

Triangle having :

=> Sin 78° =  h /30

=> 0.9781 = h /30

=> h = 30 * 0.9781

=>h =29.343

For x :

=> Sin 65° = 29.343 /x

=> 0.9063 = 29.343 /x

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math.

f = {(a, b)| for all a ∈ A, b ∈ B}.

Given, the function

f(x) = (3/2)ˣ

g(x) = (2/3)ˣ

We have to compare the graphs of the functions f(x) and g(x).

Exponential function is of the form: y = abˣ

Where a is the initial value and b is the growth factor.

a) If b > 1, then the function is an exponential growth function.

b) If 0 < b < 1, then the function is an exponential decay function.

f(x) = y = (3/2)ˣ

The function is an exponential growth function.

The rule of reflection over y-axis:

(x, y) → (-x, y)

Applying the rule, we get,

(3/2)ˣ = (3/2)⁻ˣ

= (2/3)ˣ

= g(x)

Therefore, g(x) is graph of f(x) reflected over y-axis
