Answer:

Step-by-step explanation:

Answer:

use pythag theorum you get 11.7 i thinkkk

Step-by-step explanation:

Try creating a triangle using the length of x and the length of y, so, you can tell the line goes from -5 to 5 on the x axis so that means its 10 long on x and 0 to 6 on y axis so its 6 long on y... then create a triangle and use the pythagorean theorem (the square root of (10 squared + 6 squared) which is around 11.7 .... i think, hope that helps! -prowl

SORRY THIS IS MY FIRST TIME ANSWERING A QUESTION ON HERE. I PUT IT IN THE WRONG PLACE THE FIRST TIME LOL

[tex]\\ \rm\hookrightarrow x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\\ \rm\hookrightarrow x=\dfrac{-5\pm\sqrt{25+32}}{4}[/tex]

[tex]\\ \rm\hookrightarrow x=\dfrac{-5\pm\sqrt{57}}{4}[/tex]

Problem 1

x = measure of angle N

2x = measure of angle M, twice as large as N

3(2x) = 6x = measure of angle O, three times as large as M

The three angles add to 180 which is true of any triangle.

M+N+O = 180

x+2x+6x = 180

9x = 180

x = 180/9

x = 20 is the measure of angle N

Use this x value to find that 2x = 2*20 = 40 and 6x = 6*20 = 120 to represent the measures of angles M and O in that order.

====================================================

Problem 2

n = number of sides

S = sum of the interior angles of a polygon with n sides

S = 180(n-2)

2700 = 180(n-2)

n-2 = 2700/180

n-2 = 15

n = 15+2

n = 17

====================================================

Problem 3

x = smaller acute angle

3x = larger acute angle, three times as large

For any right triangle, the two acute angles always add to 90.

x+3x = 90

4x = 90

x = 90/4

x = 22.5

This leads to 3x = 3*22.5 = 67.5

Answer:

First equation:  y = -2x

Second equation: y = 3 - x

Solution:  (1, -2)

Step-by-step explanation:

Assuming the ordered pairs of the tables are:

Table 1

(-5, 10)  (-1, 2)  (0, 0)  (11, -22)

Table 2

(-8, -11)  (-2, -5)  (1, -2)  (7, 4)

To create a linear equation, pick 2 ordered pairs. Calculate the slope by using the slope formula, then use the points-slope form of the linear equation to form the equation.

[tex]\textsf{slope }m=\dfrac{\textsf{change in }y}{\textsf{change in }x}[/tex]

[tex]\textsf{point-slope form : }y-y_1=m(x-x_1)[/tex]

Equation 1

[tex]\textsf{slope }m=\dfrac{2-10}{-1+5}=-2[/tex]

[tex]y-0=-2(x-0)\\\\\implies y=-2x[/tex]

Equation 2

[tex]\textsf{slope }m=\dfrac{-5+11}{-2+8}=1[/tex]

[tex]y+11=1(x+8)\\\\\implies y=x-3[/tex]

Solution to the System

Equate the equations and solve for x:

-2x = x - 3

⇒ 0 = 3x - 3

⇒ 3x = 3

⇒ x = 1

Substitute found value of x into one of the equations and solve for y:

y = 1 - 3 = -2

Therefore, the solution is (1, -2)

The equations are given as follows:

An equation is a combination of expressions that are equal to each other.

The ordered pairs of the tables are as follows:

Table 1:

(-5, 10), (-1, 2), (0, 0), (11, -22)

Table 2:

(-8, -11), (-2, -5), (1, -2), (7, 4)

To obtain the first equation, pick any two ordered pairs.

The slope of the equation is given as:

[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

Let's pick ordered pairs (-1, 2) and (0, 0) to find the slope of the equation.

Then,

[tex]m = \dfrac{0-2}{0-(-1)}\\m = \dfrac{-2}{1}\\\\m = -2[/tex]

So, the first equation in the point-slope form is given as follows:

[tex]y-y_1= m({x-x_1})[/tex]

Substitute [tex](x_1,\ y_1)[/tex] by (0, 0) and m by -2,

y - 0 = -2(x - 0)

y = -2x

Similarly, the slope of the second equation is obtained as follows:

[tex]m = \dfrac{-5-(-11)}{-2-(-8)}\\m = \dfrac{6}{6}\\\\m = 1[/tex]

So, the second equation in the point-slope form is given as follows:

y - (-11)  = 1(x - (-8))

y + 11 = x + 8

y = x - 3

To solve this system of equations, let's equate the right-hand sides of both equations:

-2x = x - 3

-2x -x = -3

-3x = -3

x = 1

Substitute this value of x in the first equation,

y = -2 × 1

y = -2

So, the solution is (1, -2).

Therefore, the blanks are filled in by the numbers -2 and 3. The solution of the system of equations is (1,-2).

The side of a regular hexagon is congruent with the radius of the circle the hexagon is inscribed with.  That makes the two triangles in red and green (lines are a bit offset for clarity) equilateral. At this point it's easy to compute the area of an equilateral triangle known the side length l, which is [tex]A = \frac12 l (l\frac{\sqrt3}2) = \frac{\sqrt3}4 l^2[/tex] At this point, the area of the shaded region of one triangle making up the hexagon is obtained by difference (area of the red triangle, minus area of the white:

[tex]A=A_r-A_w = \frac{\sqrt3}4 10^2 -\frac{\sqrt3}45^2 = \frac{\sqrt3}4(10^2-5^2)=\frac{\sqrt3}4\times 75\approx 32.47595[/tex]

The area of the whole shaded region, is 6 times that, or [tex]194.8557[/tex]

With tasselation:

Join the midpoint of the side of the external hexagon with the end points of the corresponding side of the inner hexagon. You have now created four equilateral squares which are congruent. (yes, my drawing skills are terrible)

The shaded region is made of 18 triangular tiles, each having an area of (see above formula) [tex]\frac{\sqrt3}4\times 5^2 = 18.8253[/tex], for a total of, again, 194.8557 square inch.
