La utilidad máxima esperada por la venta de televisores en una tienda departamental para el primer mes se representa por la sigu
finlep [7]

Explicación paso a paso:

La ganancia máxima esperada ocurre cuando dU / dx = 0

Dada la función U = - x2 + 500x + 100,000

dU / dx = -2x + 500

Dado que dU / dx = 0

Por lo tanto -2x + 500 = 0

Solución para x;

-2x = -500

x = 500/2

x = 250

Sustituya x = 250 en la función para obtener la máxima ganancia esperada como se muestra;

U = - (250) ^ 2 + 500 (250) + 100.000

U = -62500 + 125000 + 100000

U = 162,500 '

Por lo tanto, la ganancia máxima esperada por las ventas es de 162,500

PLEASE HELP ASAP!! Complete the square to rewrite the following equation. Identify the center and radius of the circle. You must
r-ruslan [8.4K]

Answer:

(i) Center = (-1, -2)

(ii) Radius = 5 units

General Circle Equation:

  • (x - h)² + (y - k)² = r²

<u>Where</u>:

  • (h, k) is the center points
  • r denotes the radius

<u>Rewriting the equation</u>:

\sf x^2 + 2x + y^2+ 4y = 20

\sf x^2 + 2x + 1^2 - 1^2 + y^2 + 4y + 2^2 - 2^2 = 20

\sf (x + 1)^2 - 1 + (y + 2)^2 -4 = 20

\sf (x + 1)^2 + (y + 2)^2 = 20 + 5

\sf (x + 1)^2 + (y + 2)^2 = 25

\sf (x -(- 1))^2 + (y -(- 2))^2 = 5^2 \quad \leftarrow  \ \bf General \ Circle \ Equation

<u>Identify the following</u>:

  • (h, k) = (-1, -2), radius = 5 units

Find the x intercepts of the parabola with vertex (-1,-16) and y intercept (0,-15)
balandron [24]
<span> first, write the equation of the parabola in the required form: </span>
<span>(y - k) = a·(x - h)² </span>

<span>Here, (h, k) is given as (-1, -16). </span>
<span>So you have: </span>
<span>(y + 16) = a · (x + 1)² </span>

<span>Unfortunately, a is not given. However, you do know one additional point on the parabola: (0, -15): </span>

<span>-15 + 16 = a· (0 + 1)² </span>
<span>.·. a = 1 </span>

<span>.·. the equation of the parabola in vertex form is </span>
<span>y + 16 = (x + 1)² </span>

<span>The x-intercepts are the values of x that make y = 0. So, let y = 0: </span>

<span>0 + 16 = (x + 1)² </span>
<span>16 = (x + 1)² </span>

<span>We are trying to solve for x, so take the square root of both sides - but be CAREFUL! </span>

<span>± 4 = x + 1 ...... remember both the positive and negative roots of 16...... </span>

<span>Solving for x: </span>
<span>x = -1 + 4, x = -1 - 4 </span>
<span>x = 3, x = -5. </span>

<span>Or, if you prefer, (3, 0), (-5, 0). </span>
