Distance = \(\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\)

\(PQ = \sqrt{(2-[-6])^{2}+(-1-[-1])^{2}}\\\\ =\sqrt{(2+6)^{2}+(-1+1)^{2}} \\\\=\sqrt{(8)^{2}+0} \\\\= \sqrt{64}\\\\= 8 units\\\\\\QR = \sqrt{(-2-2)^{2}+(4-[-1])^{2}} \\\\=\sqrt{(-4)^{2}+(4+1)^{2}} \\\\=\sqrt{(-4)^{2}+(5)^{2}} = \sqrt{16+25}\\\\= \sqrt{41}\\\\\)

\(PR= \sqrt{(-2+6)^{2}+(4+1)^{2}} \\\\=\sqrt{(4)^{2}+(5)^{2}}\\\\= \sqrt{16+25}\\\\= \sqrt{41}\)

Perimeter = \(\sqrt{41} +\sqrt{41}+8\\\)

The product of the reciprocal of 2/3, 1/8, 5 is 2 2/5

Given: 2/3, 1/8, 5

Reciprocal of 2/3 = 3/2

Reciprocal of 1/8 = 8/1

Reciprocal of 5 = 1/5

Product = 3/2 * 8/1 * 1/5

= (3 * 8 * 1) / (2 * 1 * 5)

= 24/10

= 2 4/10

= 2 2/5

Here is an example of how to draw an isosceles trapezoid:

   _______

 /                 \

/_________\

In this trapezoid, the two parallel sides (the top and bottom sides) are of equal length, and the two non-parallel sides (the left and right sides) are also of equal length. The angles between the top and left sides and between the top and right sides are equal, as are the angles between the bottom and left sides and between the bottom and right sides.

An isosceles trapezoid is a type of trapezoid where the two non-parallel sides of the trapezoid are of equal length. This means that the trapezoid has a line of symmetry through its mid-point, which divides the trapezoid into two congruent triangles. The two parallel sides of an isosceles trapezoid are also referred to as bases, and the height of the trapezoid is the perpendicular distance between the two bases.

Because an isosceles trapezoid has two congruent triangles, the angles opposite these sides are also congruent. Therefore, an isosceles trapezoid has two pairs of congruent angles, with each pair containing one acute angle and one obtuse angle. The acute angles are located adjacent to the parallel sides, while the obtuse angles are located adjacent to the non-parallel sides.

Isosceles trapezoids have several interesting properties, including that the diagonals of an isosceles trapezoid are congruent, and that the diagonals bisect each other. Additionally, the length of each diagonal can be found using the Pythagorean theorem, and the area of an isosceles trapezoid can be determined using the formula:

Area = ((a + b) / 2) * h

Where "a" and "b" are the lengths of the two parallel sides (bases) and "h" is the height of the trapezoid.

PART B:

An isosceles trapezoid is a quadrilateral with two parallel sides (the bases) and two non-parallel sides of equal length. A parallelogram is also a quadrilateral with two pairs of parallel sides.

An isosceles trapezoid can be thought of as a special case of a parallelogram where one pair of opposite sides is shorter than the other pair. In fact, if you extend the non-parallel sides of an isosceles trapezoid until they intersect, you will get a parallelogram with the same base and height as the original trapezoid.

Conversely, if you take a parallelogram and draw a line segment parallel to one pair of opposite sides, you will get an isosceles trapezoid. This means that every isosceles trapezoid can be thought of as a parallelogram with a missing piece, and every parallelogram can be thought of as an isosceles trapezoid with extra pieces added on.

So, in summary, isosceles trapezoids and parallelograms are related in that isosceles trapezoids can be thought of as special cases of parallelograms, and parallelograms can be thought of as isosceles trapezoids with extra pieces added on.

PART C:

No, we cannot use the term "isosceles" to describe a rectangle because a rectangle, by definition, has four right angles and opposite sides that are parallel and congruent to each other. An isosceles trapezoid, on the other hand, has only one pair of parallel sides and two non-parallel sides that are congruent to each other.

The term "isosceles" is typically used to describe triangles or trapezoids where two sides are congruent to each other. In an isosceles triangle, two sides are equal in length, while in an isosceles trapezoid, two non-parallel sides are equal in length. However, in a rectangle, all four sides are equal in length, not just two.

Therefore, while we can describe a rectangle as having all sides congruent to each other, we cannot describe it as an isosceles rectangle because "isosceles" implies only two sides are congruent, which is not the case for a rectangle.

Answer:

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer: the perimeter of the garden is 38 units.

Step-by-step explanation:To find the perimeter of the garden, we need to add up the lengths of all four sides.

Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2). The distance formula tells us that the distance between these two points is:

d = √[(4 - (-7))^2 + (2 - 2)^2]

 = √[11^2 + 0^2]

 = √121

 = 11

So the bottom side has a length of 11.

Moving to the right side, we can use the coordinates (4, 2) and (4, 10). Again using the distance formula, we get:

d = √[(4 - 4)^2 + (10 - 2)^2]

 = √8^2

 = 8

So the right side has a length of 8.

For the top side, we can use the coordinates (4, 10) and (-7, 10):

d = √[(-7 - 4)^2 + (10 - 10)^2]

 = √11^2

 = 11

So the top side also has a length of 11.

Finally, for the left side, we can use the coordinates (-7, 10) and (-7, 2):

d = √[(-7 - (-7))^2 + (2 - 10)^2]

 = √8^2

 = 8

So the left side has a length of 8.

Adding all four side lengths together, we get:

Perimeter = 11 + 8 + 11 + 8

         = 38

Step-by-step explanation:

72.5%

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:
