Write a polynomial in standard form that represents the area of the shaded region.

Mathematics
1 answer:
Paladinen [302]2 years ago

Answer:

Area of the smaller square is x * x, which is x^2

Area of the larger square is (x + 7)(x + 7), which is x^2 + 14x + 49

The area of the shaded area = Area of the larger square - Area of the smaller square

Area of the shaded region = x^2 + 14x + 49 - x^2

Area of the shaded region is 14x + 49.

Someone help and plz make sure it’s right :)
Airida [17]

Answer:

A triangle‘s angles should add up to 180 and the given angles sum up to 130 so x + 58 = 50 so x = -8

Hope this helped and brainliest please

Which table shows a proportional relationship between x and y?<br> Plz Help
Nastasia [14]

Answer:

The proportional table in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

<em>Verify each table</em>

Find the value of the constant of proportionality k for each ordered pair of a table.

k=\frac{y}{x}

If all the values of k are the same, then the table represent a proportional relationship between x and y

Table 1

For x=1, y=2 ----> k=\frac{2}{1}=2

For x=2, y=4 ----> k=\frac{4}{2}=2

For x=3, y=8 ----> k=\frac{8}{3}=2.7

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 2

For x=0, y=4

The line not passes through the origin

so

This table not represent a proportional relationship between x and y

Table 3

For x=0, y=0 ----> is OK the line passes though the origin

For x=1, y=1 ----> k=\frac{1}{1}=1

For x=2, y=4 ----> k=\frac{4}{2}=2

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 4

For x=1, y=4 ----> k=\frac{4}{1}=4

For x=2, y=8 ----> k=\frac{8}{2}=4

For x=3, y=12 ----> k=\frac{12}{3}=4

The values of k are the same

so

This table represent a proportional relationship between x and y

What is the range of the function y= 2sinx​
Nana76 [90]
<h2>Hello!</h2>

The answer is: [-2,2]

<h2>Why?</h2>

The range of a function shows where the function can exist in the y-axis.

To know the range of the function, we have to isolate x,

So

y=2sinx\\\frac{y}{2}=sinx\\ Sin^{-1}(\frac{y}{2}) = x

The only possible values that y can take go from -2 to 2. Taking values out of these values will give as result a non-real number.

Therefore,

The range of  the function is [-2,2]

Have a nice day!
