Answer:

(-2, 1)

Step-by-step explanation:

Hi Juliadayx! How are you?

Well, maybe you already heard about the domain and the range of a function.  

The domain is the set of values that the independent variable can take (usually referred to as the letter "x"), while the range is the set of values that the dependent variable takes, which is called f(x) or function of x.

In this case, the exercise asks you to evaluate for which values of “x” (right column of the table), the function “f(x)” takes positive values (left column of the table), the positive values also include zero. And in this case you can see that the function f(x) is only positive for the values of "x": -2, -1, 0 and 1. Therefore, the answer is the entire interval (-2, 1).

I hope I've been helpful!

Regards!

How many laps of 400m can a athlete cover in a race of 3.2km
galina1969 [7]

Answer:

8 m

Step-by-step explanation:

1) Make sure that they both have the same unit which in this case I'll change Km to m.

3.2 Km x 1000 = 3200 m

2) In order to find how much laps of 400m the athlete can cover you need to understand that one lap is 400 m, thus to find how many laps you have to divide 3200 m by 400 m

3200 m / 400 m = 8 m

Amanda's sewing a flag for a competition. The dimensions of her flag are shown below. Approximately, how many square yards of bl
DedPeter [7]

To calculate the area of the black material on the flag, we need the shape and the dimensions of the black material itself.

<em>Since the question is incomplete, as the dimension of the flag and the dimension of the black material are not given, I will provide a general explanation</em>

<em />

Assume the shape of the black material is a rectangle.

The area will be calculated as:

Area = Length * Width

Take for instance;

Length = 4yd;\ Width = 5yd

The area is:

Area  = 4yd * 5yd

Area  = 20yd^2

Assume the shape of the black material is a square.

The area will be calculated as:

Area =Length^2

Take for instance;

Length = 4yd

The area is:

Area = (4yd)^2

Area = 16yd^2

Assume the shape of the black material is a triangle

The area will be calculated as:

Area = 0.5 * Base * Height

Take for instance;

Base = 4yd;\ Height = 5yd

The area is:

Area = 0.5 * 4yd * 5yd

Area =10yd^2

So, in general.

You need to first get the shape of the black segment on the flag, then calculate the area using the appropriate formula.
