Answer:

The answer is (π/4)*r

Step-by-step explanation:

Formula length of arc when the angle given is in radian as the case given

s = r*θ

s = arc length (in radians)

r = radius

θ = central angle in radians

But when the angle given is in degrees the length is expressed as

s= 2πr*(θ/360)

Factorise fully the following:<br>a) x² + 2x<br>b) 2x² - 6x<br>c) 15x - 10x³<br>d) 9x² + 3x³​
Lostsunrise [7]

Answer:

a) x(x+2)

b) 2x(x-3)

c) 5x(3-2x^2)

d) 3x^2(3+x)

Step-by-step explanation:

a) x^2+2x

When factoring a binomial (a polynomial with two terms), what we will be looking for are the terms that are shared between them.

In this problem, it can be seen that both of these terms have and x. This means that we can factor it out to get

x(x+2)

b) 2x^2-6x

What are the common terms here?

It can be seen that each of these share a 2x, so our factored form would be

2x(x-3)

c) 15x-10x^3

What about this one?

The common factor of this one is 5x, so our factored form would be

5x(3-2x^2)

d) 9x^2+3x^3

The common factor of this one is 3x^2, so our factored form would be

3x^2(3+x)

Divide: –65.86 ÷ (–7.4)
Rina8888 [55]

Answer:

8.9


Step-by-step explanation:

The answer is 8.9 because two negatives divided by each other equals a positive. In this case, there are two negatives so you know the answer will be a positive. In the end when you divided –65.86 ÷ (–7.4), you get 8.9!

Hope this helps, have a good day. c;

(You can also type it into your calculator if you have one, and you should hopefully get the same answer.)

8x - 4y = -12 solve for y
son4ous [18]
Solving an equation means finding a value of a variable that make the equation true. This value is called the solution of the equation. A mathematical equation is just like a balanced equation. Both sides of the equation should be equal at all times. Whatever we do to one side, has to be done on the opposite side. 

8x - 4y = -12 

4(2x-y)=-12&#10;&#10; &#10;   Factor \ out \ the \ common \ term \ 4

2x-y=- \dfrac{12}{4}    Divide \ both \ sides \ by \ 4

2x-y=-3&#10;&#10; &#10;&#10; 

-y=-3-2x       Subtract \ 2x \ from \ both \ sides

y=3+2x        Multiply \ both \ sides \ by \ -1
