An exponential equation that passes through the points (2,1.8) and (5,14.4) is y = (0.6708)2ˣ

Exponential equation:

If you have two points, (x1, y1) and (x2, y2), you can define the exponential function that passes through these points by substituting them in the equation

y = abˣ

and solving for a and b.

In general, you have to solve this pair of equations:

y1 = abˣ¹ and y2 = abˣ²

Given,

The points (2,1.8) and (5,14.4).

Here we need to find the exponential equation that passes through the points.

This yields the following pair of equations:

1.8 = ab²

14.4 = ab⁵

If you divide the second equation by the first, you get

b³ = 14.4/1.8

b³ = 8

b = ∛8

b = 2

so b = 2. It's possible for b to also be equal to -2, but in this case, assume it's positive.

Now, we can substitute this value for b in either equation to get a. It's easier to use the first equation, so:

1.8 = a² x (2)²

1.8 = a²  x 4

a²  = 1.8/4

a²  = 0.45

a = √0.45

a = 0.6708

Therefore, the exponential form of the equation is,

y = (0.6708)2ˣ

Use the pythagorean theorem to find side C

The right answer is 6.4

The left side of the two-column proof should be filled as follows:

Statements                                             Reasons_______________

32 = 2x + 4y; x = 2          ⇒                       Given

32 = 2(2) + 4y                ⇒                     Substitution Property

32 - 4 = 4 + 4y - 4        ⇒                   Subtraction Property of Equality

28/4 = 4y/4                  ⇒                  Division Property of Equality

7 = y, y = 7                    ⇒                  Symmetric Property of Equality

The division property of equality states that when both sides (left and right) of an algebraic expression or equation are divided by the same (common) real number that isn't equal to zero (0), the quotients would always remain equal.

The subtraction property of equality states that the two (2) sides of an algebraic expression or equation would still remain equal even when the same number has been subtracted from both sides of an equality.

In conclusion, it has been proven that y is equal to 7 by using the two-column proof.

Take the prime factorization of both numbers to find the GCF. Then list the characteristics that they share. If they have more than one of the same factor (for example, two 2's), write them both down. Then multiply the factors they share.

A positive integer's prime factors are the prime numbers that divide it exactly. Finding these numbers is known as integer factorization or prime factorization. According to the fundamental theorem of arithmetic, every positive integer has a unique prime factorization.

The GCF (Greatest Common Factor) of two or more numbers is the greatest number among the given numbers' common factors. The greatest common factor (GCF) of two natural numbers x and y is the largest possible number that divides both x and y without leaving any remainder. GCF can be calculated in three ways: division, multiplication, and prime factorization.

[tex]\large\text{$y& = e^{\frac{1}{3}x^3+x+\text{C}}$}[/tex]

Step-by-step explanation:

Given differential equation:

[tex]\dfrac{\text{d}x}{\text{d}y}=\dfrac{1}{y(x^2+1)}[/tex]

Rearrange the equation so that all the terms containing y are on the left side, and all the terms containing x are on the right side:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}y}&=\dfrac{1}{y(x^2+1)}\\\\(x^2+1)\;\dfrac{\text{d}x}{\text{d}y}&=\dfrac{1}{y}\\\\(x^2+1)\;\text{d}x}&=\dfrac{1}{y}\;\text{d}y\\\\\dfrac{1}{y}\;\text{d}y&=(x^2+1)\;\text{d}x}\end{aligned}[/tex]

Integrate both sides:

[tex]\begin{aligned}\implies \displaystyle \int \dfrac{1}{y}\;\text{d}y &= \int (x^2+1)\;\text{d}x}\\\\\int \dfrac{1}{y}\;\text{d}y &= \int x^2\;\text{d}x}+\int 1\;\text{d}x}\\\\\ln y & = \dfrac{1}{3}x^3+x+\text{C}\\\\e^{\ln y} & = e^{\frac{1}{3}x^3+x+\text{C}}\\\\y& = e^{\frac{1}{3}x^3+x+\text{C}}\\\\\end{aligned}[/tex]

Therefore, the solution to the given differential equation is:

The length and width of the rectangular box are 13 ft and 6 ft respectively.

The length of the batter's box on a softball field is 1 ft more than twice the width.

The area of the batter's box is 78 ft².

The length and width of the rectangular batter's box can be found as follows:

Therefore,

area of a rectangle = lw

where

Therefore,

area of the rectangular box = 78 ft²

l = 1 + 2w

Hence,

78 = (1 + 2w)w

78 = w + 2w²

2w² + w - 78 = 0

Hence,

w = 6  and w =  -13  /2

we can only use positive values.

Therefore,

width = 6 ft

(b) The area of the whole shape = 76 cm squares

The shape given is formed by a triangle and a rectangle.

First we need to find the area of the triangle.

Height of the triangle = 3 cm

Base of the triangle = 4 cm

Area of the triangle = 1/2 x base x height

                                 = 1/2 x 4 x 3

                                 = 6 cm squares

Area of the whole shape = Area of the triangle + Area of the rectangle

Length of the rectangle = 10 cm

Width of the rectangle = 7 cm

Area of the rectangle = length x width

                                    = 10 x 7

                                    = 70 cm squares

Therefore, area of the whole shape = 6 + 70

We construct  an equation and calculate that number as 7 .

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions. The word equation and its cognates can have slightly different meanings in different languages. For instance, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign, whereas in French, an equation is defined as containing one or more variables.

The equation's solutions are the values of the unknown variables that satisfy the equality, which are often referred to as the variables for which the equation must be solved.

let the number be x .

9 times the number is = 9x

5 times the number added to 3 is

(x + 3) × 5

Now let us set up an equation and find that number :

(x + 3) × 5 = 9x - 13

Simplifying the given equation we get :

5 (x + 3) = 9x - 13

5x + 15 = 9x - 13

5x - 9x = - 13 - 15

- 4x = - 28

x = - 28/-4

x = 7
