What number must you add to the polynomial below to complete the square? x2 - 3x
USPshnik [31]
The coefficient of the x-term is -3. Add the square of half of that.
.. (-3/2)² = 9/4 . . . . . . the number you need to add.

x² -3x +9/4 = (x -3/2)²

_____
If the x² term has a coefficient other than 1, you need to factor that out first and deal with the remaining binomial. For example,
.. 2x² -6x = 2(x² -3x)
For this you would need to add 9/4 inside parentheses to get
.. 2(x² -3x +9/4) = 2(x -3/2)²
Of course, to keep the original value, you would need to subtract 2*(9/4) outside parentheses.
.. 2x² -6x = 2(x -3/2)² -9/2

During an experiment the following times (in seconds) were recorded. Find the median.
Debora [2.8K]

Answer:

The median is 2.65 seconds

Step-by-step explanation:

So the median is the middle number. First of all, we have to sort them into ascending order.

2.35, 2.38, 2.43, 2.65, 2.69, 2.78, 10,91.

Since this is median and not mean, we don't need to get rid of outliers / anomalies.

The middle number in that would be 2.65.

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 6) and (2, 0). a. Negative one-third c. 3 b.
statuscvo [17]

The slope of the line that passes through between (0, -6) and (2, 0) is: C. 3.

<h3>What is the Slope of a Line?</h3>

The slope of a line can be defined as the measure of the ratio of the vertical distance to the horizontal distance that exists between two points on a coordinate plane.

<h3>How to Find the Slope of a Line?</h3>

If we are given two points on a line, (x1, y1) and (x2, y2), the slope (m) is the rise/run = change in y / change in x = (y2 - y1)/(x2 - x1).

Given the following coordinates of two points as follows, (0, -6) and (2, 0), let:

(0, -6) = (x1, y1)

(2, 0) = (x2, y2)

Plug in the values into the slope formula to find the slope:

Slope (m) = (0 - (-6)) / (2 - 0)

Slope (m) = (0 + 6) / (2 - 0) [minus multiplied by minus is plus]

Slope (m) = (6) / (2)

Slope (m) = 3

Thus, the slope of the line that passes through between (0, negative 6) and (2, 0) is calculated as: C. 3.
