Answer:

9-2 is7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

1.) Let's substitute 4 for [tex]S[/tex].
[tex]9 - \frac{8}{S}[/tex]
[tex]= 9 - \frac{8}{4}[/tex]
[tex]= 9 - 2[/tex]
[tex]= 7[/tex]

Answer:

-1/4

Step-by-step explanation:

We use the formula:

[tex] \frac{y₂ -y₁}{x₂ -x₁} [/tex]

plugging in we have

[tex]\frac{ (- 1)-(1)}{(6) -( - 2)} = \frac{ - 2}{8} = - \frac{1}{4} [/tex]

Therefore our slope is -1/4

Answer:

no solutions exist

Step-by-step explanation:

You can rewrite the denominator as:

-2(2x-6) so the equation becomes:

[tex]-\frac12 \cdot \frac{2x-6}{2x-6} > 0[/tex]

from which you can see that not only should x ≠ 3, but for all values of x≠3 the equation is false.

Usando un sistema de ecuaciones vamos a ver que entran 24 libros de letras en el estante.

Vamos a usar las variables:

Por el texto, podemos saber que el peso maximo que tolera el estante esta dado por el sistema de ecuaciones.

30*x + 6*y = P

10*x + 18*y = P

Podemos igualar esas dos ecuaciones para obtener:

30x + 6y = 10x + 18y

30x - 10x = 18y - 6y

20x = 12y

x = (12/20)*y

Ahora, podemos reemplazar esto en una de las dos ecuaciones, por ejemplo la primera:

30x + 6y = P

30*(12/20)y + 6y = P

(3/2)*12*y + 6y = P

18y + 6y = P

24y = P

Así concluimos que entran 24 libros de letras en el estante.

Step-by-step explanation:

Answer:

77.4 degrees and 12.6 degrees

Step-by-step explanation:

Let the angles be x and x - 64.8.

Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :

x + x - 64.8 = 90

2x = 154.8

x =  77.4 degrees

x - 64.8 = 77.4 - 64.8 = 12.6 degrees

At x = 1000 we get the c(1000) = 2000,000. Second statement 'one thousand units have the maximum cost of $200,000' is true.

It is given that the function [tex]\rm c(x)=400x-0.2x^2[/tex] represents the total costs for a company to produce a product, where c is the total cost in dollars and x is the number of units sold.

It is required to find which statement is true, mentioned in the question.

Maxima and minima of a function are the extrema within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.

We have a function:

[tex]\rm c(x)=400x-0.2x^2[/tex]

To find the maxima and minima of any function we differentiate the function with respect to [tex]\rm x[/tex] and equate to zero.

[tex]\rm \frac{d \ c(x)}{dx} =\frac{d}{dx} (400x-0.2x^2)[/tex]

[tex]\rm \frac{d \ c(x)}{dx} =\frac{d}{dx} (400x)-\frac{d}{dx} (0.2x^2)\\\rm \frac{d \ c(x)}{dx} =400-(0.2\times2x)\\\rm \frac{d \ c(x)}{dx} =400-0.4x[/tex]

For maxima and minima [tex]\rm \frac{d \ c(x)}{dx} =0[/tex]

[tex]\rm 400-0.4x=0\\\rm x=\frac{400}{0.4} \\\rm x=1000[/tex]

If we find the seconnd differentiate, we get

c''(x) = -0.4 < 0

It means at x = 1000 we will get the maximum value of a function.

[tex]\\\\\rm c(1000) = 400(1000) - 0.2(1000)^2\\\rm c(1000)= 200,000[/tex]

Thus, at x = 1000 we get the c(1000) = 2000,000. Second statement is true.

Answer:

B

Step-by-step explanation:

To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0.                                   C(x) = 400x - 0.2x²                               dC(x) / dt = 400 - 0.4 x = 0 The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation,                               C(x) = (400)(1000) - 0.2(1000²) = $ 200,000Thus, the answer is letter B.
