Completing the Square

Step-by-step explanation:

Step 1: Define

x² = 6x + 1

Step 2: Rewrite

Subtract 6x on both sides: x² - 6x = 1

anastassius [24]

Answer:

120 MW/hour

Step-by-step explanation:

The formula of the average rate of change between two points in a function is:

Average rate of change (ARC) = f(x2) -f(x1)/(x2-x1)

Let's think the power demad as a function d(x) depending of the hour of the day, so the variable x= hour of the day.

Now we have:

d(5)= 1600

d(8)= 1960

If we apply the mentioned ARC formula = [d(8)-d(5)] MW/(8-5)hour= (1960-1600)MW/3hour= 360/3=120 MW/Hour

The correct answer is: AB = 3.11

Explanation:
Since

$cos(\theta) = \frac{base}{hypotenuse}$ --- (1)
$\theta$ = 50°
base = 2

And hypotenuse = AB

Plug in the values in (1):
(1) => cos(50°) = 2/AB

=> AB = 2/0.643
=> AB = 3.11
