{(3,7),(5,9),(6,2),(8,7),(5,11),(4,8)} what are the input, or x-values, of the ordered pairs?

Answer:

12.56 mm²

Step-by-step explanation:

[tex]A=\pi r^{2}[/tex]

Plug the given values into the area equation

[tex]A=3.14*2^{2}\\A=3.14*4\\A=12.56[/tex]

Therefore, the area of the circle is 12.56 mm².

Answer:

The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].

Step-by-step explanation:

According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.

We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:

[tex]a^{2}-b+c = 0[/tex] (2)

[tex]c = -2[/tex] (3)

[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)

The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:

[tex]y = (x-2)\cdot (x+1)[/tex] (5)

Answer:

5 yards

Step-by-step explanation:

1 yard = 36 inches

yard to inches = multiply by 36

inches to yard = divide by 36

180/36 = 5 yards

Answer:

7x² - 26x + 9

Step-by-step explanation:

(g(x)²) = (3x - 2) (3x - 2)

(g(x)²) = 9x² - 6x - 6x + 4

(g(x)²) = 9x² - 12x + 4

(9x² - 12x + 4) - (2x² + 14x - 5) = 7x² - 26x + 9

Answer and Step-by-step explanation:

For this triangle, to find x, we will use the cosine trigonometric function.

cosine functions look like this:

[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]

(The weird looking symbol is called theta, and represents an angle measurement)

Plug in the values into the equation.

cos(42) = [tex]\frac{x}{15}[/tex]

Multiply both sides by 15.

15(cos(42)) = x

Plug into a calculator.

Step-by-step explanation:

The value of x in the given similar triangles ADB and BCE is 4.5.

To solve for x in the given similar triangles ADB and BCE, we can set up the proportion of corresponding sides:

In triangle ADB, we have:

AB/BD = x/DE

Substitute the given values:

3/4 = x/6

Now, cross-multiply and solve for x:

3 * 6 = 4x

18 = 4x

x = 18/4

x = 4.5

So, the value of x is 4.5.

Answer: All Real Number

Step-by-step explanation:

This is a system of equation, and generally, there are three ways to solve:

Here, we are going to use elimination

------------------------------------------------------------------------------------

Given

-2x-y=1

-6x=3y+3

Put them in the same order

-2x-y=1

-6x-3y=3

Multiply 3 on both sides for the first equation

-6x-3y=3

-6x-3y=3

We subtract the first equation from the second equation

0=0

The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.
