PLEASE HELP. <br><br> There is a 40% chance that you will lose $25,000 if you invest...
dedylja [7]
This is a weighted average basically take the percentages and multiply them by the amount.  The total sum is the amount you will make.

0.4(-25000) + 0.25(0) + 0.35(40000)
-10000 + 0 + 14000
4000 is the expected value

Complete the square<br> to find the vertex<br> of this parabola.<br> x?+8y+2x - 23=0
trapecia [35]

Answer:

The vertex of the parabola is;

([-1], [3])

Step-by-step explanation:

The given quadratic equation is presented as follows;

x² + 8·y + 2·x - 23 = 0

The equation of the parabola in vertex form is presented as follows;

y = a·(x - h)² + k

Where;

(h, k) = The vertex of the parabola

Therefore, we have;

x² + 8·y + 2·x - 23 = 0

8·y = -x² - 2·x + 23

y = 1/8·(-x² - 2·x + 23)

y = -1/8·(x² + 2·x - 23)

y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)

y =  -1/8·((x + 1)² - 24) =  -1/8·(x + 1)² + 3

Therefore, the equation of the parabola in vertex form is y =  -1/8·(x + 1)² + 3

Comparing with y = a·(x - h)² + k, we have;

a = -1/8, h = -1, and k = 3

Therefore, the vertex of the parabola, (h, k) = (-1, 3).
