Due to the lack of spatial thinking instruction in most math classes, people say geometry is hard. People should acquire geometrical ideas easily instead.

The father of geometry, Euclid was a brilliant mathematician. The terms "ge" and "metria," which both imply "measuring," are the origins of geometry. For more than 2000 years, the Greeks' method of approaching geometry has served as the foundation for geometry.

The study of various mathematical or actual-world forms, figures, and sizes is known as Geometry. We learn about various angles, transformations, and similarities between the forms in geometry. The point, line, and plane are the main building blocks of geometry.

Everyone finds it difficult to dive into the issue of proofs. Children must realize that this issue affects everyone, even the mathematically skilled. Because they have trouble seeing how 3D, and 2D, forms, angles, and lines connect from various viewpoints, most youngsters struggle with geometry issues. Even kids who are really good at solving sum problems in math might be utterly stumped by this.

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                                                  

Where,

t represents the final amount.

a represents the initial amount

r represents the rate of growth

1+r represents the growth factor

n represents the time.

⇒  t = a(1 + r)ⁿ      

⇒  t = 10,000(1 + 0.65)ⁿ    

⇒  t = 10,000(1.65)ⁿ

Isosceles triangle

Step-by-step explanation:

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

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

Answer:

Y=-[tex]\frac{1}{2}[/tex] + 4

Step-by-step explanation:

You will be using the equation of Y= Mx+B

First you must find the Y intercept, where the line crosses the Y axis, this is at positive four, this will be your B value. then you find the slope by picking 2 easily readable points on the graph, to do this i will choose (0,4) and (2,3), then you find the change in Y and put it in a fraction over the change in x, since this is going down the slope will have a negative infront of it, so your fraction is [tex]\frac{3-4}{2-0}[/tex] which equates to [tex]\frac{-1}{2}[/tex] so your slope is -1/2 (this is M value)

so lastly you plug it all in, Y= -1/2x+4

A statistical method called the sum of squares (SS) is used in regression analysis to determine how well the data can fit the model and how dispersed the data are. Since it is determined by adding up the squared differences, the sum of squares is how it is calculated.

A sum's square is equal to the product of its summands' squares and its double products' sums of summands in twos.

Step-by-step explanation:

3/10 ÷ 1/2

3/10 x 2 = 6/10 = 3/5

The derivatives of the functions are as follows:  y' = 4x^3+2x-3x^2-3 , s'(t) =[tex]2(2-t^2)/(2sqrt t) - 2t(sqrt t+3)/(2sqrt t)[/tex] ,  f'(x) = 4x^3sin x + x^4cos x

1. y' = (2x-3)(x^2+1) + (x^2-3x)(2x) = 4x^3+2x-3x^2-3

2. s'(t) = [tex](1/(2sqrt t))(4-t^2) + (sqrt t+3)(-2t) = 2(2-t^2)/(2sqrt t) - 2t(sqrt t+3)/(2sqrt t)[/tex]

3. f'(x) = 4x^3sin x + x^4cos x

1. Begin by applying the product rule to differentiate the function. The product rule states that the derivative of a product of two functions is equal to the product of the derivatives of the two functions.

y' = (2x-3)(x^2+1) + (x^2-3x)(2x)

2. Begin by applying the product rule to differentiate the function. The product rule states that the derivative of a product of two functions is equal to the product of the derivatives of the two functions.

[tex]s'(t) = (1/(2sqrt t))(4-t^2) + (sqrt t+3)(-2t)[/tex]

3. Begin by applying the quotient rule to differentiate the function. The quotient rule states that the derivative of the quotient of two functions is equal to the quotient of the derivatives of the two functions minus the product of the two functions divided by the square of the denominator.
