What is the domain and range and when is it decreasing?

Alla [95]

The Domain is the left most part of the line to the right most part of the line (the most negative x, to the most positive x).

The Range is the bottom most part of the line to the top most part of the line (the most negative y, to the most positive y).

Domain - [0,12]
Range - [-2,4]
It starts decreasing at (0,4) and stops decreasing at (3,-2)

Hope I helped!

The equilateral triangles shown below are similar.

Drupady [299]

Answer:

Below in bold.

Step-by-step explanation:

The smaller one has side 2 and the corresponding side on the larger one is 5, so the answer is 2/5.

The individual sides and perimeter are one-dimensional, so:

The ratio of their perimeters is the same 2/5.

The ratio of their areas ( which is 2 dimensional) is 2^2/5^2 = 4/25.

Kara was making decorations for a school dance. She has a small figure to use for a pattern, but needs the actual

Sedbober [7]

Answer:

k = 5

Step-by-step explanation:

When a certain number $n$ is multiplied by a scale factor $k$ , the final number is given by

$n'=kn$

and the final number will be:

- Larger than the original number if $|n'|>|n|$

- Smaller than the original number if $|n'|$

In this problem, the number $n$ represents the size of the decoration.

If we apply the 4 scale factors given, we have:

- If $k=5$ , then $n'=5n$ : this means that the final decoration is larger than the original decoration --> this is the correct option

- If $k=1$ , then $n'=n$ : so the final decoration has same size as the original decoration

- If $k=1/5$ , then $n'=\frac{1}{5}n$ : so the final decoration is smaller than the original decoration

- If $k=-1/5$ , then $n'=-\frac{1}{5}n$ , so the final decoration is smaller and inverted

Answer:

(-5+√5)/2 and (-5-√5)/2

Step-by-step explanation:

For a general quadratic equation of the form ax²+bx+c = 0

The value of x can be gotten using the general formula expressed as:

x = -b±√b²-4ac/2a

Now given the function

f(x) = x² + 5x + 5

We can get the zeros of the function in its radical form by simply applying the formula above.

From the equation given;

a = 1, b = 5 and c = 5

Substituting this values in the formula we have:

x = -5±√5²-4(1)(5)/2(1)

x = -5±√25-20/2

x = -5±√5/2

x = (-5+√5)/2 and (-5-√5)/2

The zeros of the function in its simplest radical form are

(-5+√5)/2 and (-5-√5)/2
