A line segment with endpoints (5,8) and (-6,8) is rotated around the origin 270 clockwise how long will the new segment be?
aliina [53]

A rotation doesn't change the length of anything.

The length of the rotated line segment would be the same as the original line segment.

Because both Y values are the same, you just need to calculate the length of the X values.

5 to 0 = 5

0 to -6 = 6

Total length = 5 +6 = 11 units long.

2-sin^2x=2cos^2(x/2)
nadezda [96]
2-\sin^2x=2\cos^2\dfrac x2
1+\cos^2x=1+\cos x
\cos^2x-\cos x=0
\cos x(\cos x-1)=0

and this has solutions of x=\dfrac{n\pi}2=\dfrac{(2k+1)\pi}2 and x=n\pi=2k\pi where k\in\mathbb Z.

What is 6x-3y equivalent to?
Lemur [1.5K]

Answer

3x=y

Describe the trend/correlation<br> shown in the scatter plot below
Mkey [24]

Answer:

Negative correlation.

Step-by-step explanation:

Negative correlation means that as x increases, y decreases

Positive correlation means that as x increases, y also increases.

No correlation means that neither of the two above cases happens.

In the graph, we can see that on the right (when x is negative) the general y values are larger.

As x increases, the y-values decrease.

(Particularly, we could adjust these data with a linear equation with a negative slope)

Then this is a negative correlation.
