Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one.

azamat

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.

2. Therefore, let's call

x: the smaller one.
y: the larger one.

3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:

x+y

4. So, the area of the room is:

(x+y)(x+y)
(x+y)</span>²

Therefore, the answer is: (x+y)²

What is the range of the function y = x 2?

Leno4ka [110]

Answer:

$\mathrm{Range\:of\:}x^2:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}$

The graph is also attached below.

Step-by-step explanation:

Given the function

$y=x^2$

We know that the range of a function is the set of values of the dependent variable for which a function is defined.

$\mathrm{For\:a\:parabola}\:ax^2+bx+c\:\mathrm{with\:Vertex}\:\left(x_v,\:y_v\right)$

$\mathrm{If}\:a$

$\mathrm{If}\:a>0\:\mathrm{the\:range\:is}\:f\left(x\right)\ge \:y_v$

$a=1,\:\mathrm{Vertex}\:\left(x_v,\:y_v\right)=\left(0,\:0\right)$

$f\left(x\right)\ge \:0$

Thus,

$\mathrm{Range\:of\:}x^2:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}$

The graph is also attached below.

LuckyWell [14K]

Answer:

Final grade: 93.9%

Step-by-step explanation:

The weights are as follows: 0.25, 0.10, 0.30 and 0.35. Note that these add up to the whole, that is, to 1.00.

Then the final grade is:

0.25(94) + 0.10(99) + 0.30(92) + 0.35(94) = 93.9
