2sin^2 2x=2<br><br> In the domain [0, 2pi)
djverab [1.8K]
Please type this as 2(sin 2x)^2=2      <span>2sin^2 2x=2 is confusing.

Reducing this expression:  (sin 2x)^2 = 1

Taking the sqrt of both sides, sin 2x = plus or minus 1

If sin 2x = 1, then 2x must be pi/2 or 3pi/2, and so x must be pi/4 or 3pi/4.

Now you do this for sin 2x = -1.</span>

What is the simplified form of 12z^2-7z-12/3z^2+2z-8? ...?
gavmur [86]
It should go like this:

(4z + 3) (3z - 4) / (3z - 4) (z + 2)

Then you just cancel out (3z -4) and (3z -4), and the final simplified form of this polynomial is:

(4z +3) / (z + 2)

The length of the red line segment is 8 and the length of the blue line segment is 4. How long is the major axis of the eclipse?
liraira [26]

The major axis of the eclipse is 12 units long

The given parameters can be represented as:

Red = 8

Blue = 4

See attachment for illustration

To solve this question, we make use of the following theorem

The distance between a point and the foci sums up to the major axis

This translates to:

Major\ axis = Red + Blue

Major\ axis = 8 + 4

Major\ axis = 12

A model is going to be built of a sports car that is 132 inches long and 66 inches high. If the scale is 1:12, what will be the
taurus [48]
Scale Factor = 1:12

It means, for every in in the model, it is equivalent to 12 inches in the real.

Dimensions of the real Car = 132 * 66

So, Dimensions of the model = 132/12 * 66/12 = 11 * 5.5

In short, Your Answer would be: 11 * 5.5 cm

Hope this helps!
