Find all solutions to the equation in the interval [0, 2π). cos 2x - cos x = 0

Jlenok [28]

This is the concept of algebra, to solve the expression we proceed as follows;
cos 2x-cosx=0
cos 2x=cosx
but:
cos 2x+1=2(cos^2x)
thereore;
from:
cos 2x=cos x
adding 1 on both sides we get:
cos 2x+1=cos x+1
2(cos^2x)=cosx+1
suppose;
cos x=a
thus;
2a^2=a+1
a^2-1/2a-1/2=0
solving the above quadratic we get:
a=-0.5 and a=1
when a=-0.5
cosx=-0.5
x=120=2/3π
when x=1
cos x=1
x=0
the answer is:
x=0 or x=2/3π

In circle P diameter QS measures 30 cm.

kow [346]

<u>Given</u>:

The diameter of the circle P is 30 cm.

The radius of the circle P is 15 cm.

The measure of ∠RPS is 125°

We need to determine the arc length of QR.

<u>Measure of ∠QPR:</u>

The angles QPR and RPS are linear pairs.

Thus, we have;

$\angle QPR + \angle RPS=180^{\circ}$

Substituting the values, we have;

$\angle QPR + 125^{\circ}=180^{\circ}$

$\angle QPR =55^{\circ}$

Thus, the measure of ∠QPR is 55°

<u>Arc length of QR:</u>

The arc length of QR can be determined using the formula,

$Arc \ length =(\frac{\theta}{360})2 \pi r$

Substituting $\theta=55$ and r =15, we get;

$Arc \ length =(\frac{55}{360})2 (3.14)(15)$

$Arc\ length = \frac{5181}{360}$

$Arc \ length =14.4 \ cm$

Thus, the arc length of QR is 14.4 cm.

Hence, Option d is the correct answer.
