Mathematics

Answer:

The segment area = 113.09\ unit^2

Step-by-step explanation:

Area of the segment = \frac{(\theta)}{360} \times \pi r^2,where \theta is the angle.

We can also say that 90\ degrees is covered with one segment and we have total 4 segments (quadrants),so area of the circle divided by 4 will give us the segement area of the arc.

So area \frac{\pi r^2 }{4} =\frac{\pi(12)^2}{4} = 113.09\ units^2

So the area of the segment = 113.09 \ units^2

Describe a relationship where one quantity increases as another quantity increases
makkiz [27]

Answer:

Direct variation is the relationship between two variables, whereby if one variable increases, the other also increases and vice versa. If one variable increases if the other decreases, it is called inverse variation.

If a fraction is a negative should the negative sign be in the numerator denominator both or it doesn't matter
Angelina_Jolie [31]
Here's the rule for working with these things:

There are 3 signs associated with a fraction:
=> the sign of the numerator
=> the sign of the denominator
=> the sign of the whole fraction; (if the fraction were in
     parentheses, this sign would be written outside).

-- You can change any 2 of them without changing the value of the fraction.

-- Changing any 1 of them changes the effective sign.
___________________________________

Now, you said the fraction is negative.
So, let's start with the positive fraction, and see the different ways
that we could make it a negative fraction:

=> mark only the numerator negative
=> mark only the denominator negative
=> put parentheses around the fraction, and mark it negative outside

If you do any one of these things to a normal positive fraction,
it turns into a negative fraction.

Look at the choices you listed in the question:

-- in the numerator only ?  Yes.  That makes it a negative fraction.

-- in the denominator only ?  Yes. That makes it a negative fraction.

-- both ?  No.  That makes it the same as a positive fraction. 

-- put parentheses around the fraction, and a negative sign outside ?
   Yes.  This makes it a negative fraction.

-- it doesn't matter ?   No.  I hope you can see that it does matter.

Have I confused you ?
Is this more than you wanted to know ?
