Can someone help me with this ONE question? Write an equation.. and solve for X

Answers

Answer:

Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

x=17

Step-by-step explanation:

A 6 sided polygon is 720° degrees

so

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

flip equation:

26x+278=720

subtract 278 from both sides

26x=442

divide by 26 both sides:

x=17

Hope this helps.

Solve as a difference equation.

After caffeine is absorbed into the body, 1% is eliminated from the body each hour. Assume a person drinks an 8-oz cup of brewed coffee
containing 130 mg of caffeine, and the caffeine is absorbed immediately into the body. Find the difference equation for Yn, the amount of caffeine in
the body after n hours. Solve the difference equation. After how many hours will 65 mg (one-half the original amount) remain in the body? How
much caffeine will be in the body 24 hours after the person drank the coffee?

Answers

Solution :

Let y = amount of caffeine at a given time in body.

n = number of hours

So [tex]$\frac{dy}{dn}= - \ Y$[/tex]

[tex]$\Rightarrow \frac{dY}{Y}=- 0.01 \ dn[/tex]

ln Y = -0.01 n + C

At n = 0, Y = 130 mg

ln 130 = -0.01 x 0 + C

C = ln 130

[tex]$ \ln \frac{Y}{130} =- 0.01 \ n$[/tex]

[tex]$Y = 130 \ e^{-0.01n}$[/tex]

When Y = 65

[tex]$65 = 130 \ e^{-0.01 n }$[/tex]

[tex]$\frac{65}{130}=e^{-0.01n}$[/tex]

[tex]$\ln \frac{1}{2} = -0.01 \ n$[/tex]

n = 69.315 hours

At n = 24 hours

[tex]$Y = 130 \ e^{-0.01 \times 24}$[/tex]

Y = 102.26 mg

A number with no variable attached is called a what

Answers

Answer:

constants

Step-by-step explanation:

That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.

The term or number with no variable attached is called a constant as in the polynomial or expression.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

A number consists of the expression with no variable.

As we know, the expression is a combination of numbers, variables, and operators.

If we take an example of the polynomial.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm p(x) = a_0+a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

Here a₀ is a constant because the term a₀ has no variables.

Thus, the term or number with no variable attached is called a constant as in the polynomial or expression and the constant value does not change.

What is the degree of the simplest polynomial function with zeros at the square root of 3, 4i, and -2.

Answers

Answer:

Degree of polynomial → 4

Step-by-step explanation:

Conjugate roots theorem states that if a polynomial has a root (a + ib), then (a - ib) will be the other root.

In this question it has been given that a polynomial function has the zeros (roots) as x = [tex]\sqrt{3}[/tex], 4i and -2.

Therefore, the given polynomial will have four roots, [tex]\sqrt{3}[/tex], 4i, -4i and -2.

Function will be f(x) = (x - [tex]\sqrt{3}[/tex])(x + 4i)(x - 4i)(x + 2)

Degree of the polynomial → 4
