D-cannot be determined. g(x) is a vertical function, which is not a function. You cannot have the same x-value repeated. Because of this, g(x) has no y-intercept, and the relationship cannot be determined

Answer:

\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]

Step-by-step explanation:

Given

y = 4x - 1

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

y = 4*-2 - 1 = -9

When x = 0

y = 4*0 - 1 = -1

When x = 2

y = 4*2 - 1 = 7

When x = 4

y = 4*4 - 1 = 15

So, the table is:

\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]

Find the acute angle between the sides of a rhombus whose diagonals are 8cm and 12cm long
Sergeu [11.5K]

Answer:

67.38°

Step-by-step explanation:

The diagonals of a rhombus intersect at their midpoints and make a right angle. They also divide the angles of the rhombus in two equal angles.

So, to find the acute angle of the rhombus, we can use the tangent relation of half this angle in the small triangle made when drawing the diagonals:

tan(angle/2) = 4 / 6

tan(angle/2) = 0.666

angle/2 = 33.69

angle = 67.38°

So the acute angle of the rhombus is 67.38 degrees.

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.
