La funcion que representa el beneficio obtenido por una empresa si vende x unidades de uno de sus productos es f(x)= -70x^2+2800x-45000. ¿cuantas unidades tiene que vender para maximizar sus beneficios?

Answers

Answer 1

Answer:

[tex]20[/tex]

Step-by-step explanation:

La función es

[tex]f(x)=-70x^2+2800x-45000[/tex]

Diferenciando con respecto a [tex]x[/tex] obtenemos

[tex]f'(x)=-140x+2800[/tex]

Igualar con cero

[tex]0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20[/tex]

Doble derivada de la función

[tex]f''(x)=-140<0[/tex]

Entonces, la función es máxima cuando el número de unidades vendidas,  [tex]x=20[/tex],

A sequence of numbers is given by the formula an= 2(-1.2)^n, where n is a positive integer. What is the probability that a randomly chosen term from the first 3 terms will be negative?

A. 1/3

b. 1/2 C. 2/3 D. 0

Answers

Answer:

2 / 3

Step-by-step explanation:

Given the formula :

an= 2(-1.2)^n

At n = 1

a(1) = 2(-1.2)^1 = 2(-1.2) = - 2.4

At n = 2

a(2) = 2(-1.2)^2 = 2(-1.2)^2 ; 2 * 1.44 = 2.88

At n = 3

a(3) = 2(-1.2)^3 = 2(−1.728) ; 2 * - 1.728 = - 3.456

Number of negative numbers from first three term = 2

P(choosing a negative term) =

Number of negative numbers from first three term / total number of terms

= 2/3

Answer:

RQ = RS = 3

Step-by-step explanation:

Since RQ and RS are radii of the circle then they are congruent

let RQ and RS be x , then

Using Pythagoras' identity in right triangle QRS

x² + x² = (3[tex]\sqrt{2}[/tex] )²

2x² = 18 ( divide both sides by 2 )

x² = 9 ( take the square root of both sides )

x = [tex]\sqrt{9}[/tex] = 3

Thus RQ = RS = 3

The number 1001 is a composite number because 1001 can be divided by one, by itself and at least by 7, 11 and 13. A composite number is an integer that can be divided by at least another natural number, besides itself and 1, without leaving a remainder (divided exactly).

The factorization or decomposition of 1001 = 7•11•13. Notice that here, it is written in exponential form.

The prime factors of 1001 are 7, 11 and 13. It is the list of the integer's prime factors.

The number of prime factors of 1001 is 3.

Find the product
(3c-5)(c+3)

Answers

Answer:

3c2  + 4c − 15

Step-by-step explanation:

I tried my best if this is correct please sub to m YT I am a aspiring small creator

my YT is YoungGodlyFN.

Applying distributive property, the product of the given expression,

(3c-5)(c+3) is  3c² + 4c - 15.

In mathematics, the outcome of multiplying two integers is their product.

The given expression is,

(3c-5)(c+3)

Expanding this expression as,

3c(c+3) - 5(c+3)

Distribute the number inside the bracket we get,

3c² + 3x3c - 5c - 5x3

⇒ 3c² + 9c - 5c - 15

Combine like terms,

3c² + (9 - 5)c - 15

⇒ 3c² + 4c - 15

Thus,

(3c-5)(c+3) = 3c² + 4c - 15

Hence,

The product of the given expression is  3c² + 4c - 15.

Given the definitions of f(x)f(x) and g(x)g(x) below, find the value of (f\circ g)(-4).(f∘g)(−4). f(x)= f(x)= \,\,3x^2+4x-3 3x 2 +4x−3 g(x)= g(x)= \,\,-2x-11 −2x−11

Answers

Answer:

(f∘g)(−4) = 12

Step-by-step explanation:

Given the functions

f(x)= 3x^2 + 4x - 3

g(x) = -2x-11

Required

(f∘g)(−4)

(f∘g)(x) = f(g(x))

f(g(x)) = f(-2x-11)

f(-2x-11) = 3(-2x-11)^2 + 4(-2x-11) - 3

f(g(x)) = 3(-2x-11)^2 + 4(-2x-11) - 3

f(g(-4)) = 3(-2(-4)-11)^2 + 4(-2(-4)-11) -3

f(g(-4)) = 3(8-11)^2 + 4(8-11) - 3

f(g(-4)) = 3(-3)^2 + 4(-3) - 3

f(g(-4))  = 3(9) - 12 - 3

f(g(-4))  = 27 - 15

f(g(-4)) = 12

Hence (f∘g)(−4) = 12
