Hello!

r - pi = pi

Explanation:

↓↓↓↓↓↓↓↓↓↓

First you had to add by \pi from both sides of the equation.

r-\pi+\pi=\pi+\pi

Simplify it should be the correct answer.

r=2\pi

Answer⇒⇒⇒⇒⇒r=2\pi

Hope this helps!

If you were to draw three different parallelograms, each with a base of 6 units and a height of 4 units how would the areas comp
erma4kov [3.2K]
The areas would all be the same because they have the same side measurements.

Area = base x height

6 x 4 = 24 and will always be 24, so the area will always be 24.

GET 95 POINTS Let f(x) = 1/x and g(x)=x² + 6x. What
Dimas [21]

Answer:

hey there hope this answer helps you out

Step-by-step explanation:

we have two functions f(x) and g(x) such that

f(x) =  \frac{1}{x}

and

g(x) =  {x}^{2}  + 6x

solving for f ° g, we'll substitute the x in f(x) by the value of g(x)

fog =  \frac{1}{g(x)}

fog \:  = \frac{1}{ {x}^{2} + 6x }

taking x common in denominator

fog =   \frac{1}{x(x + 6)}

for a function to exist it should not have 0 in its denominator

checking the values of x for which the denominator of f ° g becomes 0 :-

  • x = 0 and
  • x = -6

so the function doesn't exist at values x = 0, -6

<h3>So, <u>0, -6</u> cannot be in the domain of f°g</h3>

3.-Las 80 habitaciones de un motel se podrían alquilar todas las noches si el director cobrará
BabaBlast [244]

3) Para maximizar su beneficio diario el director debería cobrar cada habitación a €56.

4) El fabricante debería ofrecer un descuento de 150€ para maximizar su beneficio mensual.

3- Dado que las 80 habitaciones de un motel se podrían alquilar todas las noches si el director cobrara 40€ o menos por habitación, y si se cobra (40+x) € por habitación, entonces 2x habitaciones permanecerán vacantes, para determinar, si cada habitación alquilada le cuesta al director 10 € al día y cada habitación no alquilada 2 € al día, qué precio debería cobrar el director por habitación para maximizar su beneficio diario, se deben realizar los siguientes cálculos:

  • 80 x 40 - 80 x 2 = 3040
  • 70 x 50 - 10 x 10 - 70 x 2 = 3260
  • 60 x 60 - 20 x 10 - 60 x 2 = 3280
  • 65 x 55 - 15 x 10 - 65 x 2 = 3295
  • 66 x 54 - 14 x 10 - 66 x 2 = 3292
  • 64 x 56 - 16 x 10 - 64 x 2 = 3296
  • 63 x 57 - 17 x 10 - 63 x 2 = 3295

Por lo tanto, para maximizar su beneficio diario el director debería cobrar cada habitación a €56.

3) Dado que un fabricante de automóviles vende 2000 coches al mes, con un beneficio medio de 1000 € por coche, y las prospectivas de mercado indican que por cada 50 € de descuento que el fabricante ofrezca a los compradores podría vender 200 coches más al mes, para determinar cuánto descuento debería ofrecer para maximizar el beneficio mensual se debe realizar el siguiente cálculo:

  • 1000 x 2000 = 2.000.000
  • 900 x 2400 = 2.160.000
  • 800 x 2800 = 2.240.000
  • 700 x 3200 = 2.240.000
  • 600 x 3600 = 2.160.000
  • 850 x 3000 = 2.550.000

Por lo tanto, el fabricante debería ofrecer un descuento de 150€ para maximizar su beneficio mensual.
