An appropriate answer of a indefinite integral must include the original integral, the solution of that integral including its integration constant.

A definite integral is an infinitesimal sum derived from a integrable function, that is, a function that exist for all value x within the range of integration.

[tex]\int {f(x)} \, dx = \lim_{n \to \infty} \sum\limits_{i=0}^{n} f(x) \Delta x + C[/tex]     (1)

The exponential function that gives the value of the car in t years after 2008 is:

[tex]A(t) = 27500(0.88)^t[/tex].

Using the function, the estimate for the value of the car in 2016 is of $9,900.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem:

Hence, the equation is:

[tex]A(t) = 27500(0.88)^t[/tex]

2016 is 8 years after 2008, hence the value of the car will be given by:

[tex]A(8) = 27500(0.88)^8 = 9900[/tex]

The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the value of the car after x years after 2008, hence:

at x = 0, y = 27500

27500 = ab⁰

a = 27500

At x = 1, y = 24200, hence:

24200 = 27500b¹

b = 0.88

y = 27500(0.88)ˣ

In 2016, x = 8, hence:

y = 27500(0.88)⁸ = 9890

The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890

The age of Cayden is given by the equation C = 32 years old

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the age of Cayden be C

Let the age of Barret be B = 11 years old

And , Barrett is 5 years less than half Cayden’s age

B = ( C / 2 ) - 5

On simplifying the equation , we get

11 = ( C / 2 ) - 5

Adding 5 on both sides , we get

16 = C / 2

Multiply by 2 on both sides , we getr

C = 32 years old

Therefore , the value of C is 32 years

Hence , age of Cayden is 32 years

The apples and oranges cost .49 cents each

Step-by-step explanation:

Next we do 3.45 divided by 7 and get .49

When we do the same for thursday, we get the same answer which confirms our answer.

Answer:true

Step-by-step explanation:

The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12.

In this question we must apply all Euclidean theorems of angles between two parallel lines cut by a third diagonal line. The internal angle between avenues B and C equals 6 · x - 18 and the external angle between avenues A and C equals 10 · x + 6.

By alternate internal angles between parallel lines we infer the measure of the internal angle between the avenues A and C equals 6 · x - 18, and definition of supplementary angles we have the following expression:

(6 · x - 18) + (10 · x + 6) = 180

16 · x - 12 = 180

16 · x = 192

x = 12

The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12. [tex]\blacksquare[/tex]

Given the information in the question, in three years, the age of Alica would be  53.

A fraction is a non-integer. It is made up of numerators and denominators. An improper fraction is a fraction where the numerator is larger than the denominator. An example is 5/2/

The first step is to determine Jessica's age in 5 years : 17 + 5 = 22

The second step is to determine Alica's age in 5 years : 5/2 x 22 = 55

Now, subtract 2 from 55: 55 - 2 = 53

Answer: 3) [tex]\frac{x+3}{x}[/tex]

Step-by-step explanation:

Start by factoring the numerator by grouping

[tex]\frac{x^3+2x^2-9x-18}{x^3-x^2-6x} \\\frac{(x^3+2x^2)+(-9x-18)}{x^3-x^2-6x} \\\frac{x^2(x+2)-9(x+2)}{x^3-x^2-6x} \\\frac{(x^2-9)(x+2)}{x^3-x^2-6x} \\\frac{(x-3)(x+3)(x+2)}{x^3-x^2-6x}[/tex]

Now factor the denominator

[tex]\\\frac{(x-3)(x+3)(x+2)}{x^3-x^2-6x}\\ \\\frac{(x-3)(x+3)(x+2)}{x(x^2-x-6)}\\[/tex]

Factor the trinomials by finding two numbers that add to get -1 and multiply to get -6. In this case the numbers are -3 and 2

[tex]\\\frac{(x-3)(x+3)(x+2)}{x(x^2-x-6)}\\\\\\\frac{(x-3)(x+3)(x+2)}{x(x-3)(x+2)}\\[/tex]

Cancel out the terms that are both in the numerator and denominator. In this case they are (x-3) and (x+2)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using Reflection, ADP and BCP are the same.

If line PD is equal to line PC, angle 1 is equal to angle 2 and angle 3 is equal to angle 4, then line AP is equal and a reflection of line BP, line AD is also equal and a reflection of line BC

In reflected angles, the sides and angles of the shape are not altered.

The original image and reflected shape above are same size and shape therefore triangle ADP and BCP are the same.
