Answer:

[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]

Step-by-step explanation:

given interval [0, 2π) = 0 ≤ x < 2π

[tex]2\sin^2(x)=\sin(x)[/tex]

subtract sin(x) from both sides:

[tex]\implies 2\sin^2(x)-\sin(x)=0[/tex]

factor:

[tex]\implies \sin(x)[2\sin(x)-1]=0[/tex]

[tex]\sin(x)=0[/tex]

[tex]\implies x=0 \pm2 \pi n, \pi \pm2 \pi n[/tex]

[tex]\implies x=0, \pi \:\sf(for\:the\:given\:interval)[/tex]

[tex]2\sin(x)-1=0[/tex]

[tex]\implies \sin(x)=\dfrac12[/tex]

[tex]\implies x=\dfrac{\pi}{6} \pm2 \pi n, \dfrac{5\pi}{6} \pm2 \pi n[/tex]

[tex]\implies x=\dfrac{\pi}{6},\dfrac{5\pi}{6}\:\sf(for\:the\:given\:interval)[/tex]

Final solution:

[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]

Hello Brainly user,

A. Multiply by 2 three times if you want to multiply by 8.

Proof:

For example, if you want to multiply 2 by 8 --> 2x8  then you can just do 2x2 = 4  4x2 = 8  8x2 = 16.

TO CHECK:

You can do 8x2 = 16.

Hence, this answer is 100% correct.

Answer:

5:2

Step-by-step explanation:

ON = OA + AN

AN = 2/5AB

AB = 5b-4a

AN = 2b - 8/5a

ON = 4a - 8/5a +2b

ON = 12/5a+2b

OP = k(12/5a+2b)

OP = OA + AP

AP = x(AM)

AM = 5/2b-4a

OP=4a-4ax+5/2bx

OP=4a-4ax+5/2bx and OP=12/5ak+2bk

Coefficients of A

4-4x=12/5k

k=(20-20x)/12

Coefficients of B

5/2x=2k

k=5/4x

(20-20x)/12 =5/4x

20=35x

x=4/7

k=5/4 * 4/7 = 5/7

OP=k(ON)

OP = 5/7

PN = 2/7

OP:PN = 5:2

I figured it out after posting the question, typing from a different account. I hope this helps somebody.

Answer:

  ? = 1000

Step-by-step explanation:

Zarea is making use of the fact that the cube root of a product is the product of the cube roots. She is factoring out the largest perfect cube in the number 6000.

  [tex]\displaystyle \sqrt[3]{6000}=\sqrt[3]{1000\cdot6}=\sqrt[3]{\boxed{1000}}\cdot\sqrt[3]{6}=10\sqrt[3]{6}[/tex]

The missing value in Zarea's work is 1000.

Answer:

Step-by-step explanation:

You have:

[tex](x+5)^2+(y-1)^2=16[/tex]

[tex](x+5)^2+(y-1)^2=4^2[/tex]

To find the center of the circle, you want to find the 'x' and 'y' values which make their respective term equal zero:

[tex](x+5)^2=0[/tex]

[tex](y-1)^2=0[/tex]

[tex]x=-5[/tex]

[tex]y=1[/tex]

The radius of the circle would be 4 due to the right side of the circle equation. Our circle is centered at (-5, 1) and has a radius of 4 units.

Answer:Susan is eight years now

Step-by-step explanation:

The area of the rectangle is the product of its base and height

The height of the rectangle is 4x - 2 units

The given parameters are:

Area = 4x^2 - 2x

Base = x

The area of the rectangle is:

Area = Base * Height

This gives

4x^2 - 2x = x * Height

Divide through by x

4x - 2 = Height

Rewrite as:

Height = 4x - 2

Hence, the height of the rectangle is 4x - 2 units

Answer: B

Step-by-step explanation:

In order to isolate 'x', we can use the number 'e' to cancel the natural log. The 'e' will cancel the natural log because they are inverse to each other:

[tex]e^l^n^(^x^)=e^-^3[/tex]

[tex]x=e^-^3=\frac{1}{e^3} =0.049787[/tex]

Answer:

If the candy was in whole of in peices

Step-by-step explanation:

A dependant variable is something you do to change a result, so breaking tha candy would be the dependant variable because they werre trying to see if breaking the candy would lead to diffrent results.

Just so you remember for next time:

an Indipendent variable is something that is constant that we can not change

and a dependent variable is something that we change to get a diffrent response.

Answer:

60,60,60

Step-by-step explanation:

The angle measures for the triangle is 60, 60 and 60.

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

We have,

The measure of three sides are 6 ,6 and 6.

Now, we know a triangle whose three sides are equal is called as Equilateral Triangle.

Also, three angles are Equal.

Using Angle Sum property

x + x + x = 180

3x= 180

x= 60

Thus, the measure of three angles are 60, 60 and 60.
